Abstract (en)
A process for manufacturing mammoth ivory jewellery, comprising the steps of: (a) slow curing a supply of rough mammoth ivory for partially drying the rough mammoth ivory; (b) cutting the rough mammoth ivory into pieces; (c) further curing the pieces of rough mammoth ivory by heating the pieces in a vacuum oven for removing moisture therefrom; (d) pressure impregnating the pieces with suitable material for preventing moisture entry into the pieces; (e) inlaying gemstones between predetermined ones of the pieces to form composite pieces; (f) further pressure impregnating the composite pieces with the material for bonding the gemstones and mammoth ivory pieces; (g) removing a portion of the material from between the gemstones and mammoth ivory pieces so as to form a shallow bed in the composite pieces as such for eliminating cracking and separation of the gemstones and mammoth ivory pieces; (h) inlaying the shallow bed with gold alloy dust for aesthetic appearance in said pieces; and (i) processing the composite pieces to acquire a final shape and polished appearance.
