ON A POOR CAST THERE ARE OFTEN BUBBLES THE MORE BUBBLES THE WORSE THE CASTING. THEY APPEAR AS LITTLE HOLES THAT ARE SPHERICAL ON THE INSIDE. A GOOD CAST WILL HAVE VERY FEW OR PERHAPS NONE AT ALL. THE ITALIANS DO A GOOD JOB ON THIER CASTING OF STATUES AND FIGURINES AND SOME OF THE FAKE IVORY IS ALSO WELL DONE. BUBBLES GET TRAPED BETWEEN THE MOLD AND THE CASTING MATERIAL WHEN IT IS POURED INTO THE MOLD. IF THERE ARE BUBBLES IN THE CASTING MATERIAL IT CAN ALSO CAUSE PROBLEMS. THERE IS A ANTI BUBBLE SOLUTION TO COAT THE INSIDE OF MOLDS AND THE APLICATION OF VIBRATION OFTEN HELPS TO GET THE BUBBLES OUT.
