I asked to my chemicals supplier about waterglass; they have liquid

(something around 20-30%)... Is the addition of NaOH strictly
necessary?
Loris, i have no idea, i am just a simple gum printer; the recipe
comes via a former list member (Klaus Pollmeier) from an old german
book.
I just used it as written; the beer was pilsener , a 6 percent german
beer.
Just another thing: the reason i tried aluminum was the 'silvery
shining', so in order to avoid the sanding -lost of shining- i used
the toothpaste, in a way a 'pumice' or?
The other thing is that for me the real 'silver shine' was obtained
with 'kitchen aluminum' (i mean the stuff used in the kitchen to wrap
things :-).

Waterglass is already alkaline in solution. What's the purpose of
adding
NaOH? Another question is about beer; with "weak beer", do you mean
"low
alcohol content" or "clear/pale" (or both)?
Thanks again,
Loris.

Interesting... What is the color of the coating (first formula)?
If it's white then I can just use this with a sizing layer on top, to
print gum on aluminum sheets or sealed wood panels. Thanks much!
What was the liquid strength of Sodium Silicate you were using
back then?
(Asking because probably I won't find this in liquid form, only
powder or
crystals...)

Loris.

Hi Loris et al,
Just a question:
did someone tried the 'old' method with the beer recipe?
I did when working with liquid light (SE2) to make bromoil
prints on
aluminium, see PF#9.
cheers,
Henk
