Softening ivory and organic compositions containing calcium using oxalic acid in the manufacture of billiard balls, piano keys, decorative objects and ornaments comprises using a chemical reaction with the organic material

摘要

Softening ivory and organic compositions containing calcium using oxalic acid comprises using a chemical reaction with the organic material which leads to a change of state and hardness of the chemical material while retaining the completely intact material. Preferred Features: Processing instruments can be used to gradually bend an elephant tusk and to produce an object from a piece which is longer than technically possible from a harder material. Material waste is reduced in the manufacture of billiard balls and piano keys.
