The paste should be of a consistency enabling it to be applied to jewellery pieces with a flux brush, ensuring solder flows where it should.
How to use: Simply wet the dish by pouring water in and tipping away the excess and then rub your borax cone in a circular motion with some downward pressure. The rough surface of the dish will grind off a little of the borax and it will mix with the water in the dampened dish to a good paste consistency ready to be painted onto your jewellery pieces prior to soldering, ensuring that your solder flows where it should.
