METHOD OF AMBER PROCESSING Russian patent published in 2013 - IPC B44C5/00 B28D5/00 

FIELD: chemistry.

SUBSTANCE: invention relates to production of amber half-stock, primarily, of minor fractions and large-size amber articles and work pieces. Proposed method consists in loading amber stock in elastic shell made from waterproof material to be sealed and placed in hydro barometric chamber. The latter is filled with fluid. Elastic shell filled with amber stock is subjected to hydrostatic compression at high fluid pressure. Note here that temperature inside said chamber is kept not higher than 120°C during the entire period of hydrostatic effects.

EFFECT: production of large-size amber articles with normal physical, chemical, aesthetic and therapeutic qualities of natural monolithic amber, recovery of industrial wastes, cheap amber half-stock.
