I

Sticklac.......... 925 parts

Sandarac ........ 875 parts

Larch turpentine.. . 270 parts Alcohol, 96 per cent 3,500 parts

The sticklac is broken up and mixed with the sandarac, put into a suitable container with a wide mouth, the spirit poured over it and set aside. After standing for a week in a warm place, frequently stirring in the meantime (best with a glass rod) and fully dissolving, stir in the turpentine. Let stand 2 or 3 days longer, then filter through glass wool. The sandarac dissolves completely in the spirit, but the stick leaves a slight residue which may be added to the next lot of lac made up and thus be treated to a fresh portion of spirit. The larch turpentine should be of the best quality. This lac is used by woodcarvers and turners and is very much prized by them.
