Volcano by Poole Pottery As the name suggests, the glaze for Volcano erupts with the dramatic hues of red and orange. This pattern comes alive in our kilns which are fired at over 1000 degrees, and it is at this point where the glaze begins to melt, the colours begin move, much like the lava over cold stones. Volcano is not just a centre piece; it is a conversation piece which celebrates craft and design at its best. Volcano is launched in several new forms in addition to the existing ranges for 2009.
