Cold vs hot reduction flame
 

I just read that there is a cold reduction flame and a hot reduction flame...can someone please explain what each is?

Also, when someone says to work with less heat does that mean decrease the propane? Is it the same as a reduction flame?

To get less heat, I turn down propane and oxygen both, or move to the far reaches of the flame.
I don't know what cold reduction/hot reduction means other than turning the flame down.

So when someone says "you are working it too hot" there is too much propane and oxygen?

Not necessarily, you may just be working to close to the candles, usually if someone says "you are working to hot" you need to work out farther in the flame, not necessarily turn down the O2 and propane.

Thanks! That clears a lot for me

What David said. If you're working too close, move out. If you are in the proper area of the flame & still too hot, turn down the flame a bit.

A cool reduction flame means turn down your oxygen. A hot reduction flame means turn up your propane. I find that some of the reducing glasses prefer a cool reduction flame to get the best oil slick colours - Psyche is one that I can think of. On the other hand if you want a lovely opaque pearly color reduction, you can use a hot reduction flame, Gail looks lovely like that.

David always explains so well and I love the visual too

Mrs D, I'm guessing your auto correct made that Gail, and it might be Gaia looks lovely like that, but it sure gave me a chuckle! :lol:
I'm so impressed that you've tried it and REMEMBERED which to do with which glass! I'm horrible about liking something but not knowing what I did to get it that way.

Is there a list somewhere of which flame type each glass likes?

Double Helix has them on their website for theirs, and some of the other silver glass places have theirs too. I don't know of any one site with them all listed, maybe someone else has one.

For instance, Sky blue does not like reducing flames if you want it to stay blue, it will get red in it with too much propane (but you might like that, so can use to your advantage).

:lol: yes Gaia, bloody auto correct :) .

Check this out. When are we getting together? I sent my cell #
