Enameling in Vacuum

This is a totally awesome list with just wonderful people and
available.

I called Mike in TX for about using a dental kiln for
enameling and he was just fantastic help. Thank you very much Mike.

One of the differences between a dental & enameling kiln is the
dental kiln uses vacuum before heating. Does anyone know what the
effective of vacuum might be on the enameling process besides helping
to get rid of pesky air pockets? The enamel might be packed together
tighter because of the vacuum will it make a difference?

Thanks to all.
