They are boiled down together, and put into barrels of pine-wood, forming, when the ingredients are mixed in equal portions, a substance of a very liquid consistence, called in France bray gras. If a thicker consistence is desired, a greater proportion of colophony is added, and it is cast in moulds. It is then called bastard-pitch.
