Fume Shots...
Man I'm sittin here trying to do the opposite.
The solid stuff is going to be mostly silver, the more pure gold seems to come out more translucent, although a very heavy gold fume with the right reg settings can get you a nice thick orange/brown gold. The further you bake in the silver the more "opaque" (white) it should turn. It's a very fine line between too much and not enough that I'm trying to figure out. Flame chemistry will have a lot to do with your resulting color. The more propane I use the more opaque I get. That includes after it is already trapped under clear.
Flame striking silver is easier again because the gold is finer/more pure (I think?) silver seems to grow visibly while gold striking is going to be very subtle change. I hope this helps.
I adjusted my regs to 40 oxy and 8 propane and I've noticed I'm getting some very interesting white/Aqua out of my silver. It's not mixing with the gold as well to get all them greens I'm used to getting. I'll probably turn back down to the 20-25/8 range.
Sooooo many variables. You can keep striking to get it more opaque, but you can over strike and it can muddy up... Fun stuff !!
Nah, nah. See, I meant to do that.
