I can't help you with the paints and papers. Any paper that is dimensionally stable after soaking in water several times would be suitable for gum.
The lamp - I don't know! Does it have a curve that shows the spectrum of light it produces? I've never used a UV light source, but it seems to me to be an integral and important part of the process.
Why not start with bromoil, which is based on regular standard black & white silver prints on certain papers (according to Gene), and requires MINIMAL investment?!
Then save up for a proper UV lamp. At least you'll be busy in the meantime :)
Black Light Bulb:
It's 24 US Dollars. Since you run 220V in Poland, I'm sure you can get a step-down transformer with a 120V secondary pretty inexpensively.
hmm. Better I find this lamp in my coutry... :D
Size paper.. Formaldehyde ?
My old brain can't keep up here. We started with Bromoil, shifted gears to Gumoil - and then moved to Gum? Three totally differing processes! :>)
That's right ... better this in one topic, not three .
The Gum process is 100% for future of this topic ;)
