Re: [ATM] Pyrex Pie Plate primary

[Guy Brandenburg <gfbrandenburg@yahoo.com>]

I cannot imagine that anything that thin would be
worth grinding into a mirror. But, David, you are
probably the world champion and expert at doing this,
since you have made TWO of them. Why don't you share
your experiences with the rest of us? Was it worth
saving the $60?

As far as those candle-holders are concerned ---
forget it.
