Note (return) — SPIRIT OF DISCOVERY.

The ware being thoroughly dried, is packed into saggars and burnt in the furnace to biscuit. Patterns for flat, or nearly flat surfaces, are put on by printing the pattern from a copper-plate with an ink composed of oxide of cobalt, oxide of iron, or other colouring matter, mixed with oil. The impression is taken on soft paper, and is applied to the surface of the biscuit, and slightly rubbed to make the print adhere: the biscuit is then soaked in water till the paper may be stripped off, leaving the print or pattern behind12. The ware is then dipped in the glaze, which is a mixture of flint slip and white lead, and the bibulous quality of the biscuit causes a sufficient quantity to adhere: the piece is then dried and again passed into the furnace, which brings out the colours of the pattern, and at the same time vitrifies the glaze.
