I prefer the insoluble chromate of lead or chromate of barium. No. 7. Hard Fire- Oxide of Tin 64 Pai-is White 32 Chromate of Lead 4 100 CLAY GLAZES AND ENAMELS. 55 Lilac. Medium Easy to Medium Fire- Oxide of Tin 4.17 Borax 41.67 Flint 29.16 Feldspar 8.33 No. 7 Pink 16.67 100.00 This will stain a lead glaze lilac by using about one of lilac to two of glaze, or, by mixing with clay, will make a lilac slip. Can be made stronger by using more of Pink No. 7 or by using more of the chromate of lead i...n making Pink No. 7. Common oxide of manganese is contaminated with iron and does not yield a good brown. Pure oxide of manganese is ex- pensive. Permanganate of potash yields quite a pure man- ganese, but must first be fritted. Below is a good way of frit- ting for a good red-brown stain. The stain will be gray, but it will make a red brown glaze: Brown Frit. Medium Fire- Feldspar 66.67 Permanganate of Potash 33.33 100.00 From 3 to 20 per cent, in glaze will produce from violet to red brown. Crimson.
