Water-colours, inks, dyes, and chemical reducers are used with such tools as scalpels, pointed brushes, airbrushes, and retouching pencils. The crystoleum, from "crystal" + "oleum" (oil), process was yet another method of applying colour to albumen prints. [34] The print was pasted face down to the inside of a concave piece of glass.
Photoshop Software assembly – Virtually assembling broken glass shards through Photoshop, after scanning or photographing all pieces, is used by conservators. Once all the details are within Photoshop, conservators will construct a copy of the glass plate by moving and rotating the parts until the glass plate is fully assembled.
Photosensitive glass vase. Photosensitive glass, also called photostructurable glass (PSG) or photomachinable glass, is a glass in the lithium-silicate family of glasses onto which images can be etched using shortwave radiations, such as ultraviolet. [1] Photosensitive glass was first discovered by S. Donald Stookey in 1937. [2] [3] [4]
Advertisement for Ansco Cyko photographic paper, 1922. Photographic paper is a paper coated with a light-sensitive chemical, used for making photographic prints.When photographic paper is exposed to light, it captures a latent image that is then developed to form a visible image; with most papers the image density from exposure can be sufficient to not require further development, aside from ...
Glass thicknesses typically range from 1.8 to 2.5 millimetres (0.071 to 0.098 in). Clear glass has light transmission of approximately 90%, absorption of approximately 2%, and reflection of approximately 8%. Whereas absorption can be reduced by using low-iron glass, reflection can only be reduced by an anti-reflective surface treatment.
Glass is enamelled by mixing powdered glass, either already coloured (more usual) or clear glass mixed with the pigments, [1] with a binder such as gum arabic that gives a thick liquid texture allowing it to be painted with brushes. Generally the desired colours only appear when the piece is fired, adding to the artist's difficulties.
An obvious English translation of cliché verre is "glass print", but this is usually avoided because the term has another meaning. This is a print that has been glued face down onto glass, the paper then being carefully rubbed off to leave the ink film adhering to the glass. This is then hand-coloured and framed as a decorative piece.
Printing on glass with UV pinning and curable inks came about almost 60 years later. In this method of printing, ultraviolet waves are applied on the inks, drying them to the glass. This method was the first to enable the digital printing on glass of any digital image including multi color and complex images.
