The following proportions I prefer: Shellac, about sixteen parts, by weight; camphor, about one part. by weinlit tale, about sixteen parts, by weight;
These substances are to be mixed, heated, ground, and molded when in a heated state, and the article formed is very strong, resen bling ivory, but it is more durable under many cir-eumstanees,in VlBW of being nninjnredby water and but little afl'ected by acids.
Various colors may be produced by the addition of pigments, such as verinilliou, white lead, impalpable white, 8w.
