The magnesia matte and calcia matte base glazes I have developed for electric firings have soft surfaces that rival the feel and utility of those achievable in reduction-fired dolomite mattes. By adding 0.2% granular manganese to M340 clay we can achieve this speckled aesthetic (outside of mug) using G2934 matte glaze.

Calcia matte ceramic glazes are “crystal mattes” while magnesia mattes are “microstructure mattes”. They have a smoother surface but can also have finely textured, even frosty, feathery or sugary surfaces, depending cooling and crystalliztion. |
