For hardening, sandarac has its place and usefulness, although, as with the naturally soft guinal condition after the solvent has evaporated, great care must be taken to use a very small proportion

A mixture of sandarac and shellac will result in an extremely hard and al for a musical instrument of any kind as it wears badly, that is, suddenly and harshly with a rough fractured edge, instead of the gentle thinning-away under usage, seen with a delicate yielding um,” with very little recommendation, as in any considerable aums hich it ar will give a good tint, although too redients, and the whole will be easily affected by damp Aloes, of which there are several kinds, have been used as a colouring ingredient, but the results are not on the whole to be considered as good
