Tuning the degree of gloss on a matte black glaze

Monday 21st July 2014

These 10-gram balls were fired and melted down onto a tile. The one on the left is the original G2934 Plainsman Cone 6 insight-live.com/glossary/146">MgO matte with 6% Mason 6600 black stain. On the right, the adjustment has a 20% glossy G2926B glaze addition to make it a little less matte. Notice the increased flow (the ball has flattened more) with the addition of the glossy. In addition, while the percentage of stain in the one on the right is actually less (because of the dilution of the transparent), the color appears darker! Tuning the degree of matteness when making color additions is not just for appearance, for functional ware it is also about achieving a surface that does not cutlery mark and is not leaching heavy metals.
