Can I cast hot wax into an Alja-Safe® alginate mold?
A: Hot wax is difficult to cast solid. The best casting technique is to build layers of wax into the mold.
Fill the mold cavity to the top with the hot, liquid wax and then pour it out. Wait a few minutes for the first layer to set up, then pour in and out again. Let it set again and pour more wax in and out again.
The finished wax casting thickness should be about 1/4" - 3/8" (0.60 cm - 0.95 cm).
Your casting needs to cool for several hours before demolding. If not fully cured, delicate details (like fingers) will break off easily.
