Reactive Glazes 1111, 1148, 1152, 1153, 1154, 1157, 1158, 1159, 1161, 1162, 1172, 1173. Are all lead free but they exceed the vanadium and/or copper threshold limit in the liquid unfired state and therefore are not non-toxic. However, they are all food safe if fired to the proper firing temperature. They behave in the manner described above for Reactive Glazes. Also be aware that some of the colors, such as 1148, 1152, 1153, 1154, 1158, 1159, 1161, 1162, and particularly 1173 are more fluid and may run. Be more careful when using them on vertical surfaces. Use fewer coats towards the bottom of the piece.
