Lovely clay roaster, oblong length measuring 12.5" length by 9" wide and interior depth is 3.5".  Interior is glazed for non-stick cooking/roasting.  Good clean condition. Appears to never have been used, no chips or cracks. Spara was particularly active from the 1950s to 1970s, known for robust, often large, mid-century modern art pottery like vases, jugs, and terracotta roasters, featuring distinctive glazes (like 'Fat Lava') and textured, incised, or hand-painted designs, now popular collector's items.
