Ok, here is my delima. I am trying to get this pillar thing down, and im running into a snag. First off, I am using OK6228, only using 1 oz pp, and minimal liquid dye. I did make a mistake and poured this one too hot, so I remelted them and did a repour. First pour was at 175, and second pour was at 185. Can anyone give me an idea of whats causing the blisters? On my second attempt, one came our perfect, but the other had the same type of blistering. Any suggestions would be GREATLY appreciated. Dont know why the pic came out so big, but you can see the whitish blister. Also, forgot to add that I did heat up my molds with my heat gun, but may not have gotten it warm enuff.
