Mucilage mixed with water has been used as a glue, especially for bonding paper items such as labels, postage stamps, and envelope flaps. [7] Differing types and varying strengths of mucilage can also be used for other adhesive applications, including gluing labels to metal cans, wood to china, and leather to pasteboard. [ 8 ]
Photographic emulsion is a light-sensitive colloid used in film-based photography. Most commonly, in silver-gelatin photography, it consists of silver halide crystals dispersed in gelatin. The emulsion is usually coated onto a substrate of glass, films (of cellulose nitrate, cellulose acetate or polyester), paper, or fabric.
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 ...
Hand-colouring with watercolours requires the use of a medium to prevent the colours from drying with a dull and lifeless finish. Before the paint can be applied, the surface of the print must be primed so that the colours are not repelled. This often includes prepping the print with a thin coating of shellac, then adding grit before colouring ...
Photographic processing or photographic development is the chemical means by which photographic film or paper is treated after photographic exposure to produce a negative or positive image. Photographic processing transforms the latent image into a visible image, makes this permanent and renders it insensitive to light.
Photographic paper was removed from the conditioner (mordant bath) and matrix was rolled into contact with photographic paper consisting of a paper base, a baryta coating to improve light reflectance and a gelatine coating without the light-sensitive silver salts in regular photographic bromide paper. The gelatine absorbs dye from the matrix ...

Root mucilage is known to play a role in forming relationships with soil-dwelling life forms. [1] [4] Just how this root mucilage is secreted is debated, but there is growing evidence that mucilage derives from ruptured cells.
