[QUOTE="Edy, post: 110772, member: 4491"] I was told today that those bubbles in the porcelain could be caused by my torch ( too much time heating until the alloy melts for cast ) , or a second cause my be the max temp of the oven with the ring is 960 C , the friend is telling me that his putting only 900 C for the casting oven . What could happen if i set my temp of the casting oven to 960 ? that could burn my alloy too ? i think the too much heating of the alloy with the torch is the main reason of my bubbles . What torch u advice me to buy and what number of the Head ( Dizza ) u use ,i got number 6 , the flame from the torch is coming 2.5-3 centimeters in diameter . What temp you got max temp in casting oven and (how much time u leave the ring at max temp if thats is any important). [/QUOTE]
