Thanks so much for offering to help. Where to start? I have now
assumed that I need to teach myself. I have read all of the orchid
postings about the blowpipe and I am still a bit confused and would
appreciate any help you can give me.
I have been told that this type of torch can be used to do
granulation on 18 kt yellow gold and on cast items. This is what I
would like to do. To date I have done granulation on 18 kt green and
22 kt yellow.
1) To begin with I am not clear about the description of needing to
hold air in one's cheeks, blowing and inhaling through one's nose -
all at the same time. The postings seem to suggest that you must be
able to do all three things simultaneously, i.e., you can't stop
blowing into the mouth piece while you are inhaling through your
nose. This seems like it is impossible to do and I am wondering if I
am not understanding the process correctly. A clarification about
this would be helpful.
2) One other posting suggested that you have to learn to use the edge
of the flame since the center is too hot and it also said something
about the angle at which the torch is held. Any advice you can give
about this as it relates to granulation would be helpful.
I have been taught put the item on a small kiln and use a bushy
flame to engulf the top of the piece. Do you use a small kiln with
this type of torch?
3) Can you recommend where I can get the best torch and the type of
regulator I should get. I will be using propane. Frei and Borel has
a mouth blowpipe torch and they recommend using a disposable
tank/disposable regulator. I hoped to use a slightly larger propane
I am sure there is so much else about this process that I don't
understand so please add any comments that you think might be helpful
