Ruska is a line of ceramics produced by the Finnish company, Arabia of Finland. The Ruska pattern was designed by Ulla Procopé in the 1960s, and it is known for its warm, earthy colours and unique glaze.

The Ruska pattern features a brown and rust-coloured glaze that is achieved by layering several different glazes over one another. The result is a rich, textured finish that looks almost like the surface of a piece of bark or stone. The glaze also has a slightly glossy finish that reflects light in a way that enhances the depth and richness of the colours.

The Ruska pattern was inspired by the natural beauty of the Finnish landscape, and it is meant to evoke the feeling of a warm autumn day in the forest. The pattern was produced in a range of items, including plates, bowls, and serving dishes, as well as coffee and tea sets.

Today, Ruska ceramics are highly collectable, and vintage pieces can be found in antique shops and online marketplaces. The warm, earthy colours and unique glaze make Ruska a popular choice for collectors of mid-century modern design and Finnish ceramics.
