I have been using a basic flux, 60% borax 30% Soda ash, 10% silica. I am also using lead as a collector metal. The ore is an oxidized quartz Gold/Silver ore. I feel I'm probably going too heavy on the silica, since there is also quartz in the crushed rock, but since I don't have an exact amount in the rock, Im still playing with the recipie.

The colloform bands contain dendrites of electrum and naumannite that must have grown in a yielding matrix of silica microspheres deposited at the same time as the ore minerals, implying that the noncrystalline silica exhibited a gel-like behavior. Quartz bands having other textural characteristics in the crustiform veins lack ore minerals.
WhatsApp: +86 18221755073
Some of the textural features of mesothermal gold-quartz veins may be best explained by the initial precipitation of amorphous silica gel (colloid), which subsequently crystallizes to quartz. This can occur in brittle-ductile shear zones where a significant fluid-pressure drop occurs during stick-slip failure.

If the gold is distributed through the quartz in a balanced and beautiful way, it can be worth a lot of money. High-end jewelers can turn the gold and quartz integration into a gemstone for an exquisite, natural, and expensive piece of jewelry. They extract the gem by cutting the quartz into slabs to expose the gold.
