The professional in resin floors told me about these granules of quartz, colored at high temperature with different iron oxides. So I thought to take some of the different colors of quartz (the grains have a diameter of 0.30 mm.) And test what happens if mixed with the white clay in various percentages. I made three bowls, one for each different color of quartz for those percentages 3-5 -6%, and my intention is to cover later with the transparent glaze in second fire. I will tell you what happens in a few days ( I hope).
However this experiment goes this Sunday we have a Super Crop,
and new guests, two canaries to the delight of Nilo and Lia our cats.
