so, what was Dr. Nichol's escharotic made of? said it was a double compound 4x more powerful than zinc chloride / arsenic. I'm assuming zinc chloride is then a escharotic, but what was his 'recipe'?

"Zinc chloride has long been known but currently practiced industrial applications all evolved in the latter half of 20th century.[5]

An amorphous cement formed from aqueous zinc chloride and zinc oxide was first investigated in 1855 by Stanislas Sorel. Sorel later went on to investigate the related magnesium oxychloride cement, which bears his name.[7]

Dilute aqueous zinc chloride was used as a disinfectant under the name "Burnett's Disinfecting Fluid".[8] From 1839 Sir William Burnett promoted its use as a disinfectant as well as a wood preservative.[9] The Royal Navy conducted trials into its use as a disinfectant in the late 1840s, including during the cholera epidemic of 1849; and at the same time experiments were conducted into its preservative properties as applicable to the shipbuilding and railway industries. Burnett had some commercial success with his eponymous fluid. Following his death however, its use was largely superseded by that of carbolic acid and other proprietary products."
