The Zsolnay factory was established in 1853 in Hungary by Miklos Zsolnay. His early efforts were to develop utility products, but the high-heat firing he used with the local clay lead to architectural ornaments that would weather the harsh conditions of the Northern European winter. The Zsolnay porcelain products were recognized at the 1873 World Exhibition in Vienna with a grand prize. These ornaments for the outside of buildings are still made today, from the same clay and using the same firing technique.
While experimenting with glazes in 1896, Zsolnay developed one named eosin, which became his other claim to fame. Although the company makes pottery in the usual multi-glaze, decorative styles for decorating the interiors of buildings, especially homes, the vases and animals with the eosin glaze are very different. The shapes are smoothly and gently modeled, just suggesting the subject, if there is one, of the piece. The iridescent, rich color of the glaze brings out the best in the simple shapes to which it is added. Rich red, deep blues and greens, the Zsolnay eosin glaze is so beautiful that it can be put on a completely plain vase and make that vase an object of luxury.
Zsolnay ceramics are available in the US and the prices on the eosin animals are reasonable. Getting one of the architectural items might be more difficult, but as the eosin is the Zsolnay porcelain claim to fame, something covered with this glaze is a better choice by the porcelain collector anyway.
