[TheForge] Venturi Burners Hot Enough?

[Bruce Freeman]

Right.  Copper can make a flame green.  But so can borax (different color =
green).  Have you used any borax in your forge?

Someone mentioned a long time ago here (Dave B?) that when things were =
just right, he got a green flame out of his forge. Me too. I have never =
melted brass, bronze, etc. in this forge so I have to agree that there may =
be some reason to this: too lean a flame is blue, too rich is yellow. What =
do these two colors combine to make in the spectrum?  Just a guess.
