Excellent for throwing, hand-modeling, and casting, Amaco No. 480 is a warm buff color peppered with dark specks when fired to Cone 5–6. At lower temperatures, it is somewhat lighter and less vitreous. The absence of grog gives this clay a smooth surface with superior plasticity.
Transparent and light matte glazes allow the dark specks to show, creating a peppered effect. Partial glazing and slip trailing also create interesting results.
Bisque fire to Cone 04 (1971°F, 1077°C). At the recommended glaze firing of Cone 5 (2205°F), shrinkage is 10.6% and absorption is 5.2%. At Cone 10 (2381°F), shrinkage is 10.8% and absorption is 1.9%.
