Wax is IGCA 1343 with 10% micro and 10% steric. pour temp was 176F and i preheated the mold to about 120F. I had the same result with only 1343 and micro as well as with 1343, micro and Vybar. We tried preheating the mold more as well as not at all and played with the pout temp. any suggestions about solving this problem?
