Pounce (powder)
Pounce or sand is a fine powder, most often made from powdered cuttlefish bone or sandarac resin, that was used both to dry ink and to sprinkle on a rough writing surface to make it smooth enough for writing. This was especially needed if the paper came " unsized", that is, lacking the thin gelatinous material used to fill the surface of the paper and make it smooth enough for writing with a quill or a steel nib. It was also used to prepare the surface when drafting with Rapidograph pens on mylar, a common drafting medium in the late twentieth century. History In the 19th century the pounce pots or sanders often had a shallow dish round the top so that pounce or sand could be returned to the pot and reused. The process is very effective for quickly drying ink, and although blotting paper has been available since the Tudor period, pounce or sand continued to be used throughout the nineteenth century because it was often cheaper.

Mylar
BoPET (biaxially-oriented polyethylene terephthalate) is a polyester film made from stretched polyethylene terephthalate (PET) and is used for its high tensile strength, chemical and dimensional stability, transparency, reflectivity, gas and aroma barrier properties, and electrical insulation. A variety of companies manufacture boPET and other polyester films under different brand names. In the UK and US, the best-known trade names are Mylar, Melinex, and Hostaphan. History BoPET film was developed in the mid-1950s,Izard, Emmette Farr"Production of polyethylene terephthalate" U.S. patent no. 2,534,028 (filed: 1948 May 13; issued: 1950 December 12). originally by DuPont, Imperial Chemical Industries (ICI), and Hoechst. In 1955 Eastman Kodak used Mylar as a support for photographic film and called it "ESTAR Base". The very thin and tough film allowed reels to be exposed on long-range U-2 reconnaissance flights. In 1964, NASA launched Echo II, a diameter balloon constr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calligraphy
Calligraphy (from el, link=y, καλλιγραφία) is a visual art related to writing. It is the design and execution of lettering with a pen, ink brush, or other writing instrument. Contemporary calligraphic practice can be defined as "the art of giving form to signs in an expressive, harmonious, and skillful manner". Modern calligraphy ranges from functional inscriptions and designs to fine-art pieces where the letters may or may not be readable. Classical calligraphy differs from type design and non-classical hand-lettering, though a calligrapher may practice both. CD-ROM Calligraphy continues to flourish in the forms of wedding invitations and event invitations, font design and typography, original hand-lettered logo design, religious art, announcements, graphic design and commissioned calligraphic art, cut stone inscriptions, and memorial documents. It is also used for props and moving images for film and television, and also for testimonials, birth an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Tattooing
Tattooing has been practiced across the globe since at least Neolithic times, as evidenced by mummified preserved skin, ancient art and the archaeological record. Both ancient art and archaeological finds of possible tattoo tools suggest tattooing was practiced by the Upper Paleolithic period in Europe. However, direct evidence for tattooing on mummified human skin extends only to the 4th millennium BC. The oldest discovery of tattooed human skin to date is found on the body of Ötzi the Iceman, dating to between 3370 and 3100 BC. Other tattooed mummies have been recovered from at least 49 archaeological sites, including locations in Greenland, Alaska, Siberia, Mongolia, western China, Egypt, Sudan, the Philippines and the Andes. These include Amunet, Priestess of the Goddess Hathor from ancient Egypt (c. 2134–1991 BC), multiple mummies from Siberia including the Pazyryk culture of Russia and from several cultures throughout Pre-Columbian South America.

Cambric
Cambric or batiste, is a fine dense cloth. It is a lightweight plain-weave fabric, originally from the commune of Cambrai (in present-day northern France), woven greige (neither bleached nor dyed), then bleached, piece-dyed, and often glazed or calendered. Initially it was made of linen; from the 18th and 19th centuries the term came to apply to cotton fabrics as well. Chambray is the same type of fabric, with a coloured (often blue or grey) warp and white filling; the name "chambray" replaced "cambric" in the United States in the early 19th century. Cambric is used as fabric for linens, shirts, handkerchiefs, ruffs, lace, and in needlework. Description Cambric is a finely woven cloth with a plain weave and a smooth surface appearance, the result of the calendering process. It may be made of linen or cotton. The fabric may be dyed any of many colours. Batiste is a kind of cambric; it is "of similar texture, but differently finished, and made of cotton as w ...

Pounce Wheel
A tracing wheel, also known as a pattern wheel, pounce wheel, and dart wheel, is an instrument with multiple teeth on a wheel attached to a handle. The teeth can be either serrated or smooth. It is used to transfer markings from sewing patterns onto fabric with or without the use of tracing paper, and can be used to make slotted perforations. Such markings might include pleats, darts, buttonholes, notches or placement lines for appliques or pockets. The double tracing wheel has two parallel wheels that can be positioned a variable distance apart. This tool can be used to transfer parallel pattern lines onto fabric, such as both the cutting line and the sewing line, where the distance between them is the seam allowance. See also * Pattern notcher A pattern notcher is a common tool used in patternmaking and sewing that creates a notch in a paper pattern A pattern is a regularity in the world, in human-made design, or in abstract ideas. As such, the elements of a patte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stencil
Stencilling produces an image or pattern on a surface, by applying pigment to a surface through an intermediate object, with designed holes in the intermediate object, to create a pattern or image on a surface, by allowing the pigment to reach only some parts of the surface. The stencil is both the resulting image or pattern and the intermediate object; the context in which ''stencil'' is used makes clear which meaning is intended. In practice, the (object) stencil is usually a thin sheet of material, such as paper, plastic, wood or metal, with letters or a design cut from it, used to produce the letters or design on an underlying surface by applying pigment through the cut-out holes in the material. The key advantage of a stencil is that it can be reused to repeatedly and rapidly produce the same letters or design. Although aerosol or painting stencils can be made for one-time use, typically they are made with the intention of being reused. To be reusable, they must remain int ...

Tudor Period
The Tudor period occurred between 1485 and 1603 in England and Wales and includes the Elizabethan period during the reign of Elizabeth I until 1603. The Tudor period coincides with the dynasty of the House of Tudor in England that began with the reign of Henry VII (b. 1457, r. 14851509). Historian John Guy (1988) argued that "England was economically healthier, more expansive, and more optimistic under the Tudors" than at any time since the Roman occupation. Population and economy Following the Black Death and the agricultural depression of the late 15th century, the population began to increase. In 1520, it was around 2.3 million. By 1600 it had doubled to 4 million. The growing population stimulated economic growth, accelerated the commercialisation of agriculture, increased the production and export of wool, encouraged trade, and promoted the growth of London. The high wages and abundance of available land seen in the late 15th century and early 16th century were repl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blotting Paper
Blotting paper, called bibulous paper, is a highly absorbent type of paper or other material. It is used to absorb an excess of liquid substances (such as ink or oil) from the surface of writing paper or objects. Blotting paper referred to as bibulous paper is mainly used in microscopy to remove excess liquids from the slide before viewing. Blotting paper has also been sold as a cosmetic to aid in the removal of skin oils and makeup. Manufacture Blotting paper is made from different materials of varying thickness, softness, etc. depending on the application. It is often made of cotton and manufactured on special paper machines. Blotting paper is reputed to be first referred to in the English language in the 15th century but there is a tradition in Norfolk, England that it was invented by accident at Lyng Mill on the River Wensum. It is reported that a Berkshire (England) paper mill worker failed to add sizing to a batch of paper that was being produced. The batch was discar ...

Technical Pen
A technical pen is a specialized instrument used by an engineer, architect, or drafter to make lines of constant width for architectural, engineering, or technical drawings. " Rapidograph" is a trademarked name for one type of technical pen. Technical pens use either a refillable ink reservoir (Isograph version) or a replaceable ink cartridge. History Early technical pens ( ruling pens) consisted of a small pair of calipers, having one flat and one bowed leg holding ink between them. By adjusting the gap between the legs the width of the line drawn by the pen could be adjusted. Such pens, kept at a constant angle to the paper, were used for ruling lines, but not for cursive handwriting, nor for off-hand flourishes. The ''Graphos'' technical pen introduced in 1934 miniaturized the caliper principle and made the points easily interchangeable. The Sheaffer company produced an expensive drafting set which included such pens for use on linen prints. These sets were often presented ...

Pumice
Pumice (), called pumicite in its powdered or dust form, is a volcanic rock that consists of highly vesicular rough-textured volcanic glass, which may or may not contain crystals. It is typically light-colored. Scoria is another vesicular volcanic rock that differs from pumice in having larger vesicles, thicker vesicle walls, and being dark colored and denser.Jackson, J.A., J. Mehl, and K. Neuendorf (2005) ''Glossary of Geology'' American Geological Institute, Alexandria, Virginia. 800 pp. McPhie, J., M. Doyle, and R. Allen (1993) ''Volcanic Textures A guide to the interpretation of textures in volcanic rocks'' Centre for Ore Deposit and Exploration Studies, University of Tasmania, Hobart, Tasmania..198 pp. Pumice is created when super-heated, highly pressurized rock is violently ejected from a volcano. The unusual foamy configuration of pumice happens because of simultaneous rapid cooling and rapid depressurization. The depressurization creates bubbles by lowering the solu ...

Technical Drawing
Technical drawing, drafting or drawing, is the act and discipline of composing drawings that visually communicate how something functions or is constructed. Technical drawing is essential for communicating ideas in industry and engineering. To make the drawings easier to understand, people use familiar symbols, perspectives, units of measurement, notation systems, visual styles, and page layout. Together, such conventions constitute a visual language and help to ensure that the drawing is unambiguous and relatively easy to understand. Many of the symbols and principles of technical drawing are codified in an international standard called ISO 128. The need for precise communication in the preparation of a functional document distinguishes technical drawing from the expressive drawing of the visual arts. Artistic drawings are subjectively interpreted; their meanings are multiply determined. Technical drawings are understood to have one intended meaning. A drafter, dra ...
