  Hadar's Clay™ Quick-fire Clays are are the "older" clays. They all require two firings with a cooling phase between firings. This results in a long firing schedule and is likely to cause cracking due to changes in temperature. The cracking requires repair and re-firing. Our newer One-fire Clays have simpler and shorter firing schedule and hardly ever crack. Nevertheless, we have not discontinued the Quick-fire clays out of respect and consideration for customers who still use them. If and when these clays are no longer in demand, they will be discontinued. Please download the Instruction Manual for Hadar's Clay™ Quick-fire Clays. |
