Weller Pottery was founded in 1872 in Fultonham, Ohio and later moved to Zanesville, Ohio. Our focused knowledge of Weller Pottery is of the luster pottery called Sicardo, named after Jacques Sicard, the glaze chemist and artist who worked for Weller Pottery during the early 1900's. Sicard brought his technology and skill from France after working for Clement Massier, and the Sicard Weller pieces have a strong similarity to the Massier lustre pottery.
Check out Jason Jacques Gallery for images and info about Clement Massier and other European Art Pottery. Awesome resource.
Weller Pottery made many lines of glazed pottery from the the beginning of 1872-1945. There was an Wisconsin Pottery Association Weller Pottery Show back in 2001, they have a list of various lines of pottery that Weller produced and an article about Weller Pottery. There are books that you can read about Weller. Here is a list of them at Just Art Pottery.
