Friedl Kjellberg (née Holzer, from 1932 Holzer-Kjellberg; 24 October 1905 — 11 September 1993) was an Austrian-Finnish ceramicist, noted especially for her work with the so-called 'rice grain' method of porcelain-making.

[3] Kjellberg's design style has been characterised as 'modern classicism'; based on tradition, but tempered by clean simplicity.

[1] Kjellberg is perhaps best known for her rice grain porcelain, a method she first discovered during a 1931 study trip to Vienna: a 17th-century Chinese dish on display at the Museum of Applied Arts had been decorated in this manner, inspiring her to experiment with the technique.

[1] She felt burdened to some extent by the popularity of her rice grain works and under pressure to create yet more designs using the method, when she herself was keen to move to new ideas and experiments.

'Pearl') rice grain porcelain set (cup, saucer, side plate and creamer) is included in the British Museum collection.
