The huge secret of course is the material. We all know ASM uses brass flakes for weight which hurts white chips. The new Paulson sponsor recently stated they use zinc oxide. I assume it has replaced lead. Not sure what BCC uses and I fear what's in the China clays!
china clays are perfectly safe- weve product tested every chip we sell
yes the brass adds density and weight -- lead was the best additive though
yea its amazing how well spots integrate with the final finished chip
we havnt progressed here to the point of pressing edgespots-we just dont have the time to work on this right now
its a catch 22- too busy to wok on this and when were too slow were screwed
