I've been doing some casting, and the last couple of casts showed signs of pitting, which is little orange skin-like dimples on the metal.  Am I not adding enough talc?  Clamping too hard?  What?


  1. I have seen some of that on my castings also. Not sure what it is. What are you using to heat up the metal? I didn't realize you had gotten that far.

  2. I use a portable electric oven burner. Apparently the problem may have been from not using enough talc and/or clamping too hard. I've made some adjustments and it is working great now.

    I've cast about six figures. I'll try to get a pic up soon.
