Hi Steffi, hi everyone,
as this is my very first post here after some years of reading, I first want to introduce myself
I'm Martina from southern Germany, lampworking since 2006, addicted to boro (but still doing soft glass things too) since 2009 or so. I'm also in the german forum Perlentreff with the same nick, and (hopefully) well know there, although I didn't post so much in the last 1 or 2 years.
Now to your question. Boro silverglass (which is DAP) is to be treated pretty much like soft glass silver glass. It needs either a thick cover or a little reduction to get the beautiful colours. As I have a setup with a cricket torch and one 5 LPM oxycon, I automatically have low oxy and work a little on the reducing side. This works well with colours like DAP. You can even only flamestrike it (I don't have a kiln).
What is your setup? Do you have more oxy than me?
You can PM me here or at Perlentreff, so that I can answer you in German, that makes things easier
Martina
