Borax cones & dishes are a traditional way of making your own flux for precious/non precious soldering.

Pour a little water into your borax dish, the residual water should be enough to form a paste. Grind the cone down on the dish using a round motion, this will form a soldering flux paste.

If there is some flux remaining in the dish, leave it to set. You can just add water and repeat the process when you need to make flux again.
