It seems like the colour-making works was somewhere in Via Gellia but, as can be seen at least the stock was sold in 1827, a year after the firm folded. Could not the works have become a lead smelter at that time? I'm sure that the colour-making works got some of their lead from Henstock, they got some from Philip Gell as well. I think he was the landlord of the works.
