Do people here use commercial parting compound(s)? Is green sand different from Petrobond as far as what works best? I have read of or used the following 1) chalk/calcium carbonate; 2) talc/talcum powder; 3) commercial parting dust - what the people I do foundry with use; 4) "sill-sand," mentioned in Ammen's books... 5) silica flour - (Silicosis, here I come!) Is graphite a possibility?
I ran out of my usual baby talc (non perfumed) and had to nick some from the wife, my flasks now smell like a ponce’s boudoir
we just discussed this diatomaceous earth pool filter powder and Graphite powder apply it with a muslin parts bag, wipe the graphite into the pattern with the bag, blow off the excess, the dust the DE powder with a bag, lumps will show on your finished casting Someone will give you a link to the oterh post I'm sure V/r HT1
I just threw out 5kg of parting from Winters (Moving, long story) but I believe it was calcium carbonate and worked well with oil bonded sand. I have used regular scented talk in the past to good effect.
