Re: ATM AstroFest Mirror Silvering

I don't know the current exchange rate, but a 95-96 catalog for Alfa
(Johnson Matthey) lists 100g  for $63.00, 25g for 24.80. Aldrich lists 100g
for $73.80, 25g at $26.30. These are all "ACS reagent" grade (99+%), which
should be plenty good for plating. 25 g ought to coat a lot of mirrors, I
would think.
