Apparatus for amending metals by nitre (saltpetre)
Both pictures on this plate are part of Johann Rudolf Glauber's treatise on the 'Continuation of Miraculum Mundi'. The upper image depicts 'A Gift offered to all diligent Physicians ... The manner of concentrating and amending of Metals by Nitre' (the distilling vessel is designed as 'a Man ... made of Iron, having two noses on his head'). The lower picture shows the furnace used in 'a Gift presented to rich Merchants', again involving the use of nitre (saltpetre) in 'the emendation of Metals'. Plate facing p.189 in the book The works of the highly experienced and famous chymist, John Rudolph Glauber, containing great variety of choice secrets in medicine and alchymy ... (English translation by Christopher Packe, London, 1689).
