Hi Joe,

I am trying to bond glass and silicon by fushion bonding in a furnace, I
raised the temperature up gradually to the annealing temperature of glass
(around 600 Degree C). I used to put an alumina block (not heavy) on the top
to press glass and silicon together. few of the glass area adhered to the
silicon but most of them didn't.
