My ceramic research start with the question, whats's the effect of sand on the color and structure of the ceramic piece. I went to different places to see if there is a difference and collect samples. I was curious because sand excist out of different minerals. I wanted to know if I can show the difference by adding sand in different amounts to the clay.

I also wanted to see what else I can do with it, so I also tried to make a glaze with it, fired it in different ways. You can see that when you use the same sand added in a glaze but fired in different ways (oxidation, 1260 C, reduction and oxidation 1050 C) you get different results.
