[QUOTE="disturbed, post: 45008, member: 4763"] your burnout time seems a little excessive, as does your bench cool. I prefer to put the rings into a hot oven while they are still hot themselves, I would bench set for maybe 3-5 mins. If you burnout the investment for to long it will start to break down and lead to flash issues like your pics, I prefer microstar investment. anyways..... first burnout stage to reach temp starting around 180 should be bout 15 minutes till at max temp around 700, then burnout for no more than 45 minutes. do this burnout time for ALL castings.. less chance of flash. bulk your margins in wax and finish them back after casting so you dont have shy margins around the interface.. thats what works for me anyways,, hope it helps [/QUOTE]
