Students’ works, ceramic, Bohemia, 1907-1912

Works modelled from nature were very much the order of the day around 1900 at the Technical College for Ceramics in the Bohemian town of Teplice (German: Teplitz-Schönau). Plants, people and living animals all served as ‘models’.

A small lot of students’ works, created between 1885 and 1917, comprises a wide array of ceramics (earthenware, stoneware, porcelain) and various designs (receptacles, plates, figurative sculptures, and tiles). The directory attached also provides valuable information on the finishing techniques used (onglaze and underglaze painting, sharp-fire glaze, muffle enamel colours, salt glaze and tin glaze).

Showcased here are three examples from this group of objects at the Technisches Museum Wien: ‘Cockerel, stoneware, with coloured glaze, 1907’ (Fig. 1), ‘Vase, soft porcelain, with underglaze pastes, 1908’ (Fig. 2) and ‘Plate, hard porcelain, muffle enamel colours, 1911/1912’ (Fig. 3).

Ceramics can be finished in all sorts of ways, for example with coloured glazes, e.g. tin glazes coloured with metal oxides (cockerel). In addition to the glaze, ceramics can also be painted by applying the paints under the glaze or on top of it. If the ceramic is sharp-fired at high temperatures, sharp-fire underglazes (vase) or sharp-fire onglazes are obtained. But not all metal oxides are capable of withstanding the high (sharp) firing temperatures of up to 1,500 °C, which is why the palette of very durable sharp-fire colours is limited.

By contrast muffle enamel colours are fired at lower temperatures of up to 900 °C (plate). With this onglaze technique the colours applied to the pre-glazed porcelain fuse with the glaze when fired once again. The palette of enamel colours is vast, but the durability of the glazes/paintwork is reduced.

The small lot of students’ ceramic works features a vast spectrum of handcrafted products and is therefore a valuable source of production techniques.
