check

chip
a defect in the surface caused by material that has been broken away
crackle
a network of fine cracks found in a variety of objects including paintings, lacquers, inlays, and ceramics.
Crevice
a narrow aperture and often penetrates more than one layer

traction crackle
an “alligatored” pattern of complex branching, with wide, disfiguring apertures.

crazing
a fine system of crackling in a varnish layer, usually found in aged films in their final stages of drying and embrittlement
dirt/grime
dirt of any kind accumulated on top of the varnish or finish; on top of the surface; or embedded under the varnish or finish on the surface of the object
Discoloration
a partial or overall changer in color caused by aging, light and/or chemical agents. Yellowing, and darkening can occur, along with bleaching, the light of color, discoloration/staining is often caused by adhesive residue or moisture that has seeped through breaks in the glass
fill
the material used to replace areas of loss; fill is the inpainting
Flaking
the loss of tiny, flat, loose bits of the varnish, paint, or finish on the surface of an object, or even the surface itself
gouge
a defect in the surface where material has been scooped out
grime
soil held on the surface
ground
layers of material applied to prepare a surface for painting; usually a pigment in binding medium
buffered paper
paper made with a calcium chemical compound used in order to not disturb the art
authority file
