Hi,

“The Theory & Practice of Goldsmithing”
I have been able to find answers to all my questions in this book…pits, inclusions, blisters, waving/ curling…the what’s happening…the why it’s happening…how metal forms…behaves…deforms…reacts…it’s crystaline structure…a really great book

Thanks Jo & Julie!! Jeff
Interesting video. I got an explanation for why, from time to time, I get blisters on my sheet after annealing it. The single tip vs multi orifice tip discussion has me heading off to do some experiments, first of which is to even get the single tip to light as that is one of the reasons that I tried multi orifice tips in the first place. Mixing boric acid and borax together to extend the temperature range also makes sense. Thanks for sharing…Rob

What I love about making jewelry is that even after over 50 years I still learn new things.

I dug out my single orafice tips. They came with the Meco when I was still using regulated acetylene and O2. I don’t think that I ever used them on the propane and O2 concentrator setup. The #2 tip worked fine and I was able achieve a reducing flame that did a small (26) gram melt in very little time using the concentrator for O2. I have used Paige tips for a long time and have been, generally, happy with them. Now that they are out of business, it is nice to know that there are other options. I know that some of you have used the multi orafice tip from Otto Frei. How are they working out? Thanks…Rob
