At conferences we've argued about craft and art and addressed the politics of ceramics. My guess is that it would turn out a clear/whitish glaze. But those studying materials feel ill-equipped to create balanced, fitted, strong, color compatible glazes, opening the kiln is still like pulling the handle on a slot machine. It is true, many authors and teachers have been singing the 'learn-your-materials' song. This one is part of a larger project centered on the G1214M recipe. Great base glaze. I am comparing 6 well known cone 6 fluid melt base glazes and have found some surprising things. If you just want to mix it the traditional way, start with about 85 water to 100 powder (by weight) and mix well using a propeller mixer. I get very good melt fluidity when B2O3 comprises about 25% of the fluxes. It is true that too much will compromise matteness or raise the melting temperature, but it is surprising how many glazes will take plenty of silica without any trouble. Fusion frit F69 or Ferro 3249 are the magic behind this type of approach (Frit 3249 contains a little CaO in addition to the MgO). Kaolin 25 Whiting 5 Dolomite 20 Cornwall Stone 50 Cobalt Carbonate .5 20 Wollastonite 20 Fritt 3134 (F 4108) 20 Potash Feldspar 20 Silica 20 China Clay Notes.

But consider: I can list the oxides on the fingers of my hands and they have predictable behavior. I would like to demonstrate how we can view materials as both powders with a physical presence that shapes the properties of the glaze slurry and also as 'oxide warehouses' that supply building blocks to the fired glass. An interesting part of supplying this on the computer is that the feldspar also sources CaO so you have to go back and adjust the Wollastonite again to restore CaO to 0.6. I chose to use a clean and consistent feldspar named Kona F-4, 15% is needed. These people have not been on the roller coaster, they have been making really exciting things happen in the studio and on the factory floor, learning from their mistakes as never before.

To get around 0.55 formula units of CaO (of a total of 1.0) we need to top up the CaO already supplied by the frit. It turns out that substituting MgO for other fluxes is by far the most effective way to reduce glaze thermal expansion. This is not an ad, it is part of this article! Now lets talk about the oxides in the above limit chart. Weathered green when thick, breaks bronze.
