LEADLESS GLAZE ON POTTERY.
[To THE EDITOR OF THE "SPECTATOR."]
Sin,—From Canon Gore's letter in your recent issue of December 22nd, 1900, one might be led to infer that the ques- tion of procuring pottery dipped in leadless glaze now remains entirely in the hands of the public, and is simply a question of demand. May I state that this is not at all the case, and that a really commercial leadless glaze is far from being pro- duced as yet? The mere exhibition in a London shop of a variety of articles dipped in leadless glaze is no proof that the article can be produced in bulk. Canon Gore and others who have recently entered the arena on the question of leadless glazes appear to overlook the fact that such an important ingredient as lead cannot be eliminated from a glaze without years of careful trial and experiment by the manufacturers. That pottery manufacturers have long been engaged in careful experiments in this direction is a fact which deserves more widespread recognition by the public. These experi- ments have led to the conclusion that an innocuous glaze can be produced which is not leadless, but can have no ill-effects on the operatives engaged in its production and application. Glazes of this type are on the market now, and will very shortly, it is believed, be in general use by manufacturers. It is difficult to see why such a glaze should not satisfy the most ardent of the philanthropists who have recently taken the cause of the " dipper " so much to heart. am, Sir, &c.,
