Glossary of Terms
Edition 5.0[1-29]
Art Resource

Marie-Therese Wisniowski

Preamble
There are currently seven data bases on this blogspot, namely: Glossary of Terms; Timelines of Fabrics, Dyes and Other Stuff; A Fashion Data Base; Glossary of Colors, Dyes, Inks, Pigments and Resins; the Glossary of Fabrics, Fibers, Finishes, Garments and Yarns, the Glossary of Art, Artists, Art Motifs and Art Movements and lastly, the Glossary of Paper, Photography, Printing, Prints and Publication Terms.

The Glossary of Terms, Timelines of Fabrics, Dyes and Other Stuff, A Fashion Data Base, Glossary of Colors, Dyes, Inks, Pigments and Resins, the Glossary of Fabrics, Fibers, Finishes, Garments and Yarns,the Glossary of Art, Artists, Art Motifs and Art Movements and the Glossary of Paper, Photography, Printing, Prints and Publication Terms have been updated. These Glossaries will be updated in the future to incorporate more definitions that we should be aware of in our art practice.

If you find any post on this blog site useful, you can save it or copy and paste it into your own "Word" document etc. for your future reference. For example, Safari allows you to save a post (e.g. click on "File", click on "Print" and release, click on "PDF" and then click on "Save As" and release - and a PDF should appear where you have stored it). Safari also allows you to mail a post to a friend (click on "File", and then point cursor to "Mail Contents On This Page" and release). Either way, this or other posts on this site may be a useful Art Resource for you.

The Art Resource series will be the first post in each calendar month. Remember - these Art Resource posts span information that will be useful for a home hobbyist to that required by a final year University Fine-Art student and so undoubtedly, some parts of any Art Resource post may appear far too technical for your needs (skip over those mind boggling parts) and in other parts, it may be too simplistic with respect to your level of knowledge (ditto the skip). The trade-off between these two extremes will mean that Art Resource posts will hopefully be useful in parts to most, but unfortunately may not be satisfying to all!


Introduction
It used to begin with just a dictionary, then thesaurus, and before too long perhaps even an encyclopedia - all bound and proudly standing on your bookshelf. Sooner or later as you gathered technical tomes, with extensive glossaries, you always wished that you could combine the glossaries into one super compendium that reflected your interest. Unfortunately, Blogger have got size restrictions and so I had to create well focussed glossaries, rather than a single all-encompassing one.

I started my own glossary of terms several decades before Wikipedia. Initially, Wikipedia was only as technically correct as its contributors - and that, in some cases was found to be wanting. Then in its second incarnation, they required their editors to list sources, encouraged their readership to challenge incorrect entries, created dialogues in order to eventually move to agreed definition(s) or description(s). It has become a great resource – a one-stop shop for unpacking definitions. What is more - it is fast and efficient.



How good is it in defining terms used in dyeing, fabrics and textiles? Not bad at all! However, there are some terms you cannot find, some fabrics that are not listed and some dye processes poorly worded. For example, the difference between two natural dyes such as substantive and adjective dyes is that one does not require a mordant whereas the other does. Wikipedia does not even have an entry for “substantive dyes” and so it cannot make clear the difference between them.

What Wikipedia also does not let you do is - browse. Search algorithms are getting smarter on that score. Just Google a word or a phrase! However, when you look up "Kersey" in Wikipedia you do not see "Kasha" (which is defined as: “A type of flannel that has black and colored fibers in the filling yarns.”) Serendipity sometimes works wonders. “Ah, I have often wondered what was Kasha - thanks Kersey!” That is why some Emeritus Professors lament a digitized world - they see serendipity fast disappearing in a manically ordered information systems. A little bit of serendipity, they say, is the basis of some great discoveries.

The first week of every month will give an overview of some area which underpins the art practice of dyeing or printing on cloth. The intention is to present small parcels of knowledge, which will be understood by novices, who may wish to enter this new continent of art called ArtCloth or dabble in the traditional fine-art prints on paper.

Marie-Therese Wisniowski's ArtCloth Work Titled - Entropy (Detailed View).
Techniques: Multiple discharge processes, silkscreened, stenciled and mono printed employing gels, transparent, opaque and metallic paints on rayon.
Size: 110 cm (width) x 320 cm (length).

The references - that were invaluable in this compilation - are given at the end of the glossary. All errors are mine. Enjoy!

Glossary of Terms

Acetone: A solvent. One of its uses is to remove rosin from metal.

Acetylate: To introduce an acetyl group (CH3CO-) into an organic compound. In textile chemistry this may be due to the reaction between a hydroxyl group(s) (-OH) with acetic acid and/or acetic anhydride.

Acid: When dissolved in water, an acid is a proton donor; on the pH scale, it has a pH lower than 7. Rainwater, sourced from the ocean, is slightly acidic with a pH ca. 5.0 - 5.6.

Acid Free: Material and paper without acidity; also termed "pH neutral".

Aging: Variety of techniques for simulating the effect of time and wear on new paint, wood or plasterwork.

Aggregate: The coarse or inert ingredients which are mixed with cement in the making of concrete.

Alcohol: Organic compounds containing one or more -OH groups.

Alkali (Base): When dissolved in water, a base is a hydroxide anion (OH-) donor. On the pH scale, its pH is greater than 7. For example, the lilac plant prefers soil that is slightly basic (pH 7.1 - 8.0).

Altimeter: Instrument that measures the height of an aircraft above the ground.

Amide Group: It has the chemical formula -CONH-. When found in nylon polymers it is called an amide group; when found in wool polymers it is called the peptide group.

Amino Goup: A radical with the chemical formula -NH2. This group is found in amino acids.

Amino Acid: A building block of proteins. There are approximately 22 amino acids available for protein construction. Amino acids contain a basic amino group and a carboxylic acid group.

Ammonia: Ammonia is a colorless gas. However, the public has incorrectly associated the name with ammonium hydroxide (which is the aqueous solution of ammonia). Hence in the latter form, it is often used as a cleaning agent and also in natural dyes as an additive when fermenting orchil-yielding umbilicate lichens. An alkali, it used sparingly in dyebaths, otherwise copious use of it will impair the quality of the fiber. A small amount added to a yellow bath (such as goldenrod) will result in a yellow-green color.

Arcade: A series of arches carried on columns. When the columns and arches are fixed against a wall, this is known as blind arcade.

Aromatic: A compound containing a benzene ring system.

Atom: The smallest particle of an element.

ATSIC: Aboriginal and Torres Strait Islander Commission.

Auxochrome: A polar group or a negative atom, which intensifies the absorption of light by a dye. In some cases it will alter the hue of the dye.

Baume Scale (abbr. Be): A scale of specific gravity of liquids.

Biomorphic: Having the qualities of living form.

Bond: The linkage between atoms in a molecule and between molecules and atoms in a crystal. It is also referred to as a chemical bond.

B.P.: In chemistry it is an abbreviation for boiling point.

Buffer Solution: Any solution that is formulated to a specific pH and that has the ability to oppose any pH change by the small addition of acids or bases. For example, human blood is buffered at a neutral pH (i.e. pH 7).

Cantilever: The free part of a horizontal member that projects into space, seemingly without support, while its internal end is anchored in the main structure.

Carragheen: The seaweed carragheen, is commonly used as an emulsifier in food, can also be used to thicken the floating bath for marbling techniques.

Cartridge Paper: Cartridge paper comes in several weights (e.g. 130 - 150 g) and is often used to apply paint or dye to it. It is good for collaging or intercutting into other designs, as it is flat and untextured.

Cassone: (plural: cassoni). Italian meaning: “large chest”. Term generally used to refer to decorated Italian wedding chest.

Catalyst: A chemical that speeds up a reaction, without it being altered by the reaction. In time, side products usually poison its catalytic activity.

Cation: A positive charge carrier.

Cellulose: The main constituent of the cell wall of all plants. It is a polymer of glucose (a natural sugar).

Certosina: Geometric patterned inlay of wood, bone, mother of pearl, and metal favored in North Italian centers such as Venice.

Chemical Affinity: In chemical physics and physical chemistry chemical affinity is an electronic property by which dissimilar chemical species feel an attraction toward each other and so are capable of forming chemical compounds (e.g. electron deficient systems are attracted to electron rich systems). It can also refer to the tendency of an atom or compound to combine by a chemical reaction with atoms or compounds of unlike composition.

Chevet: French term for east end of church with chancel, ambulatory, and radiating chapels.

Clay Plaster: Versatile, natural “breathing” material.

Cloisonne: A means of setting cut stones or enamel between thin metal “walls” which have been fixed to a back-plate.

Dado: Lower part of the room wall when it is faced or colored differently from the upper part.

Degree of Polymerization: The average number of monomer units in a polymer chain. More specifically, it is the average molecular weight.

Density: Density is equal to mass divided by volume and so in the SI system has units of kg/m3 or g/cm3. The density of a substance varies at different temperatures (due to volume that changes as temperature changes) and so is quoted at particular temperatures. For the Imperial System - see Conversion Factors.

Dispersion Force: It is a force that is caused by an induced dipole – induce dipole contribution to more general force called the intermolecular force. That is, a dispersion force is when one neutral molecule (dye) can induce a dipole (negative and positive charges separated within it) in another neutral molecule (fiber) and vice-versa, thus causing a cohesive interaction between the two. It is the second strongest force between neutral molecules after the hydrogen bond.

Drywall: Plaster substitute such as plasterboard.

Exothermic: Describes a chemical process, such as a reaction, that releases heat in order for it to occur.

Flash Point: The flash point is the lowest temperature at which a flame above the solvent will cause the solvent's vapor to ignite. Obviously, the lower the flash point the more readily the solvent's vapor will ignite at room temperature. In general those solvents with a flash point below 21oC are considered the most dangerous, while any solvents with a flash point below 32oC are still considered dangerously flammable. For example, methanol and ethanol have flash points of 11oC and 12oC, respectively. On the other hand butanol has a flash point of 36oC.

Glass Transition Temperature of a Polymer: The glass transition temperature (Tg) of polymer is an accurate measure of its softness. A polymer that is too soft will lead to a cold flow in an adhesive and pick up dirt in a coating or fabric. A polymer, which is too hard, may crack when stressed or may not be able respond to movements in a fabric. Most polymers in fabrics have a glass transition temperature around room temperature.

Glucose (D form): A common sugar present in many plants and in human blood. It is a constituent of starch, cellulose and sucrose etc. and can be obtained from the latter in the hydrolysis with acids or enzymes.

Intermolecular Forces: Commonly known as van der Waals’ forces (named after a scientist who first investigated the phenomenon), intermolecular forces can be weakly attractive and repulsive and so they operate at close range to be effective. In the case of the attractive force, it arises principally from: ion-ion interactions; ion-dipole interactions; dipole-dipole interactions; dipole-induced dipole interactions etc. It is the principle force that binds a dye to a fiber in hydrophobic fibers.

Ion: A carrier (atom or molecule etc.) possessing charge(s).

Ionic: Possessing charge(s).

Ionic Bond: A bond between two ions due to a mutual electrostatic attraction (e.g. table salt is made from the attraction of a positive sodium ion to a negative chlorine ion within a crystal lattice). In the case of dyeing, the mutual attraction generally is between positive centers in the fiber and negative centers in the dye molecule and between negative fiber sites and positive centers in the dye molecule. The dyeing of wool provides a simple example of this.

Later examples also display enamel colors. They depict religious and secular subject-matter and were designed to be viewed at close quarters, often in domestic and other secular settings. They became popular in the last quarter of the fifteenth century, and the largest number were made in the Low Countries.

Salt: Sodium chloride is common table salt. There are several forms: sea salt (contains other salts in smaller amounts such as magnesium chloride); coarse pickling salt and ordinary iodized salts (contains potassium iodide etc.) The addition of a salt to dye bath softens the colors and slightly retards the rate at which the fiber absorbs the dye. It is used to “draw” the color from certain dyestuffs, namely flowers, barks, lichens and roots, and is sometimes added to these when they are soaking out. A final hot water and salt rinse is beneficial when rinsing out some colors after dyeing. This adds in the fastness of these shades and prevents too much color “rubbing off” after yarns are dry.

Santeria: An African Cuban religion derived from Yoruba beliefs and rituals.

Saturated Covalent Bond: A single covalent bond that does not take part in additional reactions. In textile chemistry, saturated covalent bonds occur most frequently between two carbon atoms, and or between one carbon (C) atom and an atom of hydrogen (H), oxygen (O) and/or nitrogen (N). Saturated covalent bonds are strong, stable and so not reactive.

Scoring: It is - in bottle cutting, scratching a fine clean line into the surface of the bottle to provide a break line.

Second: It is the duration of exactly 9192631770 periods of radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom.

Sign: In communication studies, any means whereby one human, animal or plant seeks to affect behavior or condition of another by means of communication; “sign types" are those universal (such as letters of the alphabet) which are drawn on to produce "sign events", physical embodiment of sign-types (such as speech, or a piece of writing).

Snow White: Same as white, chalky, lily white. The color of snow; the whitest of whites. Zinc white.

Sodium formaldehyde sulfoxylate (Reducing Agent): Commercial names: Formosul and Rongalite C. It is a general purpose reducing agent. It is easy to handle and produces a good white on cellulose, cellulose acetate, triacetate and 100% silk fabric. It is rarely used on wool because it may cause fiber damage and shrinkage problems, because it functions best in an alkaline pH range. With some finer fabrics the production of a “halo” effect may cause some problems.

Soft Water: The absence of mineral salts in the water (see hardness of water).

Solubility: The degree to which a substance will dissolve in a solvent such as water.

Solvent: (i) Usually toxic (but it can be non-toxic) chemical used to dissolve oily block out materials from the screen or used as a pressurized removing agent (e.g. water pressure); (ii) Part of oil-based paints that evaporates during drying.

Solvent Cement: Special adhesive to join sheet plastic. It works by dissolving a small amount of the plastic on each of the surfaces being joined. When the material re-hardens, the surfaces are permanently joined.

Specific Gravity: The density of substance, expressed as the ratio of density of water.

Standard International Units (SI Units): It is also known as the International System of Units (abbreviated SI from Systeme International D'unites). It is the modern variant of the metric system that is based on a power of ten between various categories of length (e.g. metre and centi-metre), mass(e.g. kilogram and gram), volume (litre and milli-litre), and temperature (the melting of ice - 0oC - and the creation of steam - 100oC).

Tingari: Commonly described as a group of Aboriginal ancestral beings, with one or more dominant men or women, who brought law and culture to the peoples of the Western desert region (Australia).

Threshold Limit Value (TLV): This is a limit value which gives the lower safety limit. Any solvent with a TVL less than 200 ppm should be avoided or treated with considerable caution. For example, the TVL of gasoline is ca. 300 ppm. In the case of solvents you need to prevent contact with eyes and skin for a TLV of 2 mg m-3 (2ppm). Note: Sometimes Occupational Exposure Limits (OEL) is used in lieu of TLV.

Time: Both the SI unit and the Imperial system have the same units for time.
1 Year = 3.16x107 seconds (s); 1 Month (31 Days) = 267.84 x 108 s; 1 Day = 8.64 x 104 s; 1 hour = 3.6 x 103 s; 1 minute = 60 s.

Tjukurpa: The "Tjukurpa" or "Dreamtime" or "Dreaming" as it is sometimes loosely translated into English, is fundamental to Central Australian Aboriginal life. It defines traditional aboriginal law and religion and encompasses the land and its creation and all that exists. Different language groups of Central Australia have different words and spellings for the same concepts, sometimes capitalized and sometimes not. Some of these are: Tjukurpa (Pitjantjatjara language), Altyerre (Arrernte), Jukurrpa (Warlpiri) and Tjukurrpa (Pintupi - Luritja). It is incorrect to assume that all aboriginal groups in Australia have "Dreamings" or even similar "Dreamings" to those in Central Australia.

Tog: A metric unit for insulation value equal to the thermal resistance that will allow heat flow of one watt per square meter from a temperature differential of 0.1oC.

Tongue-and-Groove: Joint made between two boards by means of a tongue projecting from the edge of one board that slots into a groove along the edge of the other.

Unsaturated Covalent Bond: A double or triple bond, which in general are more reactive than saturated covalent bonds and so can undergo addition reactions. Also used in connection with saturated fats (which contain saturated covalent bonds i.e. single bonds - not reactive) and unsaturated fats (which contain unsaturated covalent bonds - double or triple bonds - very reactive)

UPC: Initials of "Universal Product Code" (see "bar code").

Vajara (Chinese Term): A Buddhist symbol representing a thunderbolt.

van der Waals Forces: These forces are really due to intermolecular forces but on occasion have been named after the Dutch physicist who investigated their effects on the properties of gases. They are weak attractions or repulsions that operate at close range between all types of atoms and molecules and in the cases of attractions are the principal reason that dyes will bond in hydrophobic fibers. See intermolecular forces.

Vault: A masonry, brick or concrete arched structure forming a ceiling or roof over a hall; barrel vault, groin vault, ribbed vault.

Vertex: Plural - vertices. In geometry, meeting-point of lines that form an angle.

Vine Black: Made by calcining selected wood and other vegetable products. This pigment and the other blacks referred to it are members of a group of rather impure forms of carbon made by burning selected, but rather second-rate materials of vegetable, animal, and petroleum origins. They all have a bluish undertones and when mixed with whites will produce blue-greys. They are inferior to the lampblack group in intensity and pigment properties. While these materials are probably permanent enough for most practical uses, it is wiser to select one of the purer forms of carbon as listed under Black Pigments. The vine black group should not be used in fresco or to mix with cement, mortar etc. because of efflorescence from water-soluble impurities, which they always contain.

VOC: abbrev. Volatile organic compound.

Voussoir: A wedge-shaped block used in the construction of a masonry arch.

Wonderful Marie-Therese,
I will certainly let students know and will add your site/blog link to my blog when I make the next entry.
What a talented and generous artist you are. I am so glad to have had the honour of working with you. Sadhana xx

Dear Marie-Therese, I've just pinned a link to your incredible glossary to my Pinterest board entitled Stitching Inspiration. I hope every single one of my 200+ followers does the same! What an open, sharing heart you have! We met last summer at the Surface Design Association Conference in Minnesota. I was working/volunteering Hospitality and so was disappointed not to be able to study with you, but when our paths cross again, I plan to make it work! I will also share your Glossary as a PDF with my Fiber Artists Study Group at the Textile Center in Minneapolis. Blessings, Kristin Hoelscher-Schacker

What a fabulous resource! Thank you Marie-Therese. I love to know the names and meanings of things. Houndstooth, Huckback, Hue…it reads like poetry!

It is really important that when you blog, you reference the sources that you get your information from. I have always tried to give credit to those who have become before me. If I have failed I will correct it. This glossary is - as I have tried to acknowledge - a small effort on my behalf. I am so proud to name those who have become before me and worked so hard to keep you - the interested - so learned about the many terms and fabrics. I raise my glass to them.
