<ab id=”p085v_b4d”>[or metal] fills with bubbles. Most of all, make sure that the cast is always higher than the molded thing, since the sand swells very often when reheating, even in the middle, and therefore with the molded thing remaining higher than the cast, the metal cannot run easily or at all nor enter at all. Also make sure that the mold & the cast are indeed reheated. Also cast in one go & outside of the wind. And if your medal is really thin, when you want to mold it, put a card, or two or three thicknesses of paper, so that the mold will be lower than the cast.
