I wanted the black and white, but by no means is it the color I set out to get I have just stumbled upon the method really and I know the color comes from certain minerals in the type of tap water I rinse the barrel with, u can literally watch it change in front of your eyes..... As for other work all i can show u is a damascus 10 gauge L.C. Smith barrel Ive done.... Im 26 years old and really just started getting into the doubles about 6 months ago... Ill post pictures of the other barrel later on
