Can I apply the other Kaolin instead of EPK's

Recommended Posts

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
