AvesApoxie Sculpt 1 lb. Bronze, 2 Part Modeling Compound (A & B)

Can I mix the white and brown to get a lighter brown?

can this be used as an overcoat to regular clay?

Could I use liver of sulphur with this to give it a patina?

How much volume of material do you get? ...I realize it it s 16oz by weight... I'm not sure how that translate into quantity/volume
