Early Indian chintz, that is, glazed calico with a large floral pattern, was primarily produced using painting techniques. Later, the hues were applied by wooden blocks, and the cloth manufacturers in Britain printed calico using wooden block printing. Calico printers at work are depicted in one of the stained glass windows made by Stephen Adam for the Maryhill Burgh Halls, Glasgow. Confusingly, linen and silk printed this way were known as "linen calicoes" and "silk calicoes". Early European calicoes (1680) were cheap plain weave white cotton fabric, or cream or unbleached cotton, with a design block-printed using a single alizarin dye fixed with two mordants, giving a red and black pattern. Polychromatic prints were possible, using two sets of blocks and an additional blue dye. The Indian taste was for dark printed backgrounds, while the European market preferred a pattern on a cream base. As the century progressed the European preference moved from the large chintz patterns to smaller, tighter patterns.
