This clay, L4115J3S, a Plainsman 3D-based experimental body, fires vitreous and dense (it contains 0.2% granular manganese). These glazes are very durable and functional. The outside glaze on both is G2934W (adds 10% zircopax). In our C6DHSC firings this produces as matte a surface as is possible without having excessive staining problems. Left mug inside glaze: An 85:15 mix of G2934 matte (without zircopax) and G2926B clear glossy. Right mug inside: G2926B clear glossy ball-milled, over this body it produces a striking visual surface. These mugs look as close to cone 10R dolomite-glazed ware as we have ever seen!
Dolomite matte glazes have the potential to be very silky and pleasant to the touch, while at the same time being hard, durable and non-crazed (if they are formulated correctly).
