This melt flow test was done at cone 6 to demonstrate the difference in melt viscosity between a calcia matte (left) and a magnesia matte (right). In simplest terms, the former depends on a fluid melt to provide the needed mobility for tiny crystals to form during cooling, those crystals scatter the light and soften the surface to give the matte effect. The latter requires a stiffer melt to help prevent leveling during cooling and host phase separation to produce a surface that scatters light.

Magnesia Matte
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). |
