Stone-washed
Stone washing is a textile manufacturing process used to give a newly manufactured cloth garment a worn appearance. The process became popular in the 1980s, as acid jeans gained popularity; however, stone washing has roots going back to 1960s Surfwear, surfer apparel. Stone washing also helps to increase the softness and flexibility of otherwise stiff and rigid fabrics such as canvas and denim. Although stone washing increases a fabric's flexibility, it shortens the life-span of the jeans. The process of stone washing can be costly, as freshly stone washed jeans must be washed many times in order to remove the grit from the process. Along with high production costs, stone washing can be detrimental to the environment, due to the excess grit that is removed as fabric is being stone washed. This leads many manufacturers to pursue other methods to achieve a distressed appearance. The process uses large stones to roughen up the fabric being processed. The garments are placed in a larg ...

Pumice
Pumice (), called pumicite in its powdered or dust form, is a volcanic rock that consists of extremely 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 rapidly 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 sol ...
