Question on settings
 

I have a Nortel midrange + torch, a 10 lpm concentrator and tanked propane.
What settings on the oxycon and propane should I set for working boro?

Try 4-5 pounds propane and 8-10 ponds oxy.

Thanks. I think that was what I had it set for today when I tried to make a few boro beads.

Liz, you usually work soft glass, right? When working boro, tuck it in close to the torch. You need to sink in a lot of heat. If you work it like soft, it will take forever.

Good tip! I added another oxy to my setup and wondered why it was still taking a while. I work further up in the flame out of habit. I will try it closer next time.

You don't need to turn like mad when working boro. It moves and heats much slower. Slow down and enjoy the dance.

I would recommend also using a larger size mandrel. Because of the heat required, you WILL burn thru a thin one. Double dip too - or use a bead release that can hold up. I use Fusion Bead Release.
