Re: Everclear Alcohol and Gum

I always knew that you couldn't drink the dime store denatured
(something learned in High School???). I just thought they came from
different sources, rather than being deliberately "poisoned"!

So, either my testing was too limited (not enough samples) or too much
alcohol in the sizing is a bad thing (and thus the weaker Vodka had
more stain resistance than the stronger denatured).

I think I will work with cheap vodka for a while. I've always really
hated vodka taste, so won't be tempted to imbibe while working ;-(

Now, if I could just find a good photographic reason to keep a stock of
good German dark beer in the darkroom.........
