leopold Posted March 15, 2019 Report Share Posted March 15, 2019 Hi everyone, I found people apply EPK kaolin in most of glaze. May I apply the other's? Link to comment Share on other sites More sharing options...
Babs Posted March 15, 2019 Report Share Posted March 15, 2019 I think you would be fine. However test as if you are going for an identical glaze look you may get a slight difference as some Kaolins may contain different impurities. Link to comment Share on other sites More sharing options...
neilestrick Posted March 15, 2019 Report Share Posted March 15, 2019 You probably won't notice any difference with other kaolins. I've substituted lots of kaolins over the years and never had an issue. Link to comment Share on other sites More sharing options...
Bill Kielb Posted March 16, 2019 Report Share Posted March 16, 2019 Glazes are basically silica, alumina and flux often with colorants. Silica and Alumina will not melt below 3000 degrees so the flux helps them melt at a lower temperature. Glazes are basically the combination of roughly 13 base chemicals. The clay used in a glaze generally provides about 10-20% of the chems as well as helps keep the mixture suspended so it doesn’t fall to the bottom of the bucket and separate. Look at the chart below and pick those with similar properties if you seek similar results. If you substitute gold art for EPK your results are likely to be very different. Epk, grolleg, OM4, relatively similar. As to the rest, not so much Link to comment Share on other sites More sharing options...
