AnaLucia 3 Report post Posted March 28, 2018 Hi, I am new to this forum and if possible, would like to have some advice. I fired a group of sculptures on my new electric kiln (third fire), and most of them have come out with 'white spots'. I am attaching photos so you can see them. I bisque fired them them to 1000 c The clay I used was: Valentine Clays. ES 180 Sculpting/Pizza Clay. I wonder if it is the clay or the temperature of the kiln. Any advice?
