lime blast
A defect in leather, characterized by a rough
grain surface and/or hard or dark colored patches,
or patchy dyeing. It is caused by excessive
exposure to air of a limed skin, resulting in some
of the lime being converted by atmospheric carbon
dioxide into insoluble calcium carbonate.
Prolonged exposure may also cause some drying of
the skin, resulting in hard, brownish, translucent
patches in the finished leather. (306 )
