Re: Preparing Al sheets; other factors

just an idea, but my first thought when hearing "weak beer" is to get 
rid of the carbonation before using it.
(the dictionary is not of real help here...) i mean, get rid of the 
bubbles before use.

in the bostick & sullivan forum seems to be a lot of talk about alu use 
and sizing too lately.
here's the link, if you haven't seen it yet:

i've got a question about silica:
i have some waterglass ( liquid). silica is powdered. but are those two 
things the same (more or less), only that one is liquid, the other on 
powdered? could i use waterglass instead of silica?
