BASTARD PITCH, is a mixture of colophony, black pitch, and tar. 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 consistency, called in France bray gras. If, on the contrary, it is desired of a thicker consistency, a greater proportion of colophony is added, and it is cast in moulds. It is then called bastard pitch.
