Opalines are to be distinguished from opaline glass, a process mainly developed in the 16th-18th centuries to imitate Chinese porcelain. Progress in the crystal industry led to technical changes throughout the 19th century. The white opaline of the early days (1800-1810), or "opal crystal", was soon joined by a new process combining silica, potash, lime and phosphoric acid. This other white opaline, known as "rice paste", was a great success. It was a semi-opaque glass that could be made in shades of pink, yellow, blue or green and yellow by adding metallic oxides. In the first third of the 19th century, the prevailing neoclassicism led to the adoption of simple shapes inspired by Greek, Roman, Etruscan and Egyptian art. More fanciful lines appeared in the second third of the 19th century, from the reign of Louis-Philippe onwards. Technical improvements - particularly in moulding - led to a diversification of shapes, which initially tended to become rounder.
