Early Pacific Pottery Artware and Gardenware is extremely desirable and very difficult to find. You can find early artware is glazed in the same colors as early Hostessware: Apache Red, Yellow, Green and Pacific Blue, but also in a selection of custom glazes, both solids and blends. Later artware pieces (primarily produced between 1937-41) are more commonly found.
Towards the late 1930s, artware took on a more fanciful form and the Pacific Pottery artware division began to glaze primarily in matte pastel colors popular in the day. Typical colors include (in matte) white, light green, light yellow, light blue, and (in gloss) pink and aqua. Two-tone blends are also common. In the later artware line (post-1935), there close to 400 documented pieces. Towards the end of pottery production, later artware can be found in Coralitos glazes, and many artware pieces carry the Coralitos brand sticker.
