Original G2571A cone 10R silky matte improved
Project Name Cone 10R Silky Matte Hosting the Titanium/Color Mehchanism Project Codenumber UnAssigned Notes Dolomite matte glazes have long been a staple at cone 10R. However there are many that achieve the matte surface by not being adequately melted or by excessive surface crystallization. These are inferior, producing staining, cutlery marking and lack the pleasant silky surface. Many of these also have the issue of crazing. Pictures |
Original Cone 10R Silky Matte Base Recipe
Total:100.00 Auto Unity Formula
Notes *This is a silky matte with a very nice texture to the touch. It will not be a "matte white" unless Zircopax is added. Zircopax is also needed for other additions (e.g. rutile) for opacity. This recipe was improved at G2571B (talc instead of dolomite, more wollastonite, calcined kaolin, no silica).

G2571A Rutile Bamboo
Total:113.50 Auto Unity Formula
Notes *We transplanted the rutile and zircopax addition into this base after seeing it in another glaze recipe. This base produced a more velvety surface with less tendency to stain. This glaze is worth mixing in a large bucket, we use alot of it. Pictures G2571A L4028 bamboo on P6589 H550 This adds rutile and zircopax to the matte white recipe.

Cone 10R Silky Matte Blue
Total:104.50
Notes *G2571A has been our go-to dolomite matte base for many years. It has very low thermal expansion, by virtue of low levels of KNaO, and fits bodies very well. And it thrives on colorant and variegator additions. So it seemed a natural to make our rutile blue using this.

Total:109.00 Notes *This adds the titanium and red stain to the new fritted base of G2571B. Fabulous results. However the amount of titanium is too little high, losing a bit of the silky feel of the surface. Next time try 3% and 3.5%.
