It may be safely affirmed that few, if any, hardporcelains except the Japanese have ever been made with so littlealkaline matter as this porcelain of Bristol. And when we studysoft English porcelains, we shall often find in them no less than40 per cent, of bone-earth, alkaline matters, and fluxing salts,associated with no more than 40 per cent, of silica and 20 percent, of alumina. It must not be assumed that all Bristol porcelain was identicalin composition. Champion specified the use of various propor-tions of china clay and china stone, ranging from four to sixteenof the former to one of the latter. His glaze also was not alwaysmainly felspathic, but sometimes contained additions whichrendered it more fusible. There are four different marks on Bristol porcelain.
