[QUOTE="dmonwaxa, post: 21139, member: 927"] My guess its either two things: 1.Investment breakdown, from high heat for too longh a hold time or if sprue former and spruing is rough, then when molten alloy enters the mold the sharp pieces may break off and become dispersed in the casting. 2. Gassing or super heating, when the alloy is being molten compressed air or oxygen may become incuded in the melt if the torch is improperly adjusted. [/QUOTE]
