Borax cones are a dry form of flux. Used with water and a Borax Dish to form a paste. The amount of water required is minimal - wet surface of the dish and tip out excess - what remains is sufficient. What you are trying to aim for is a toothpaste consistency. Move the cone in a circular motion (whilst applying a little pressure) in one area of the dish. Due to the ceramic texture fine deposits of the cone are left in the water and in turn form a paste. The paste is then used as a flux to keep the joining area clean while soldering.
