In laminated glass bending process 2 glass sheet will be superposed in a furnance.The seperation powder will be interposed between layer for avoid 2 glass sheet being bound together.
I'm trying to find substance that can be replaced baby powder as a lubricant in the process of glass-bending. It has to be cheaper, able to be found as a powder, and it should not be a human hazard.
Recently, I found magnesium sulfate, and I believe that it could be used for my purposes. However, it is so hard to find $\ce{MgSO4}$ in a compact and powdered form.
Does anybody know of any suitable replacements for baby powder in the process of glass-bending?
