This is a boiled soap. A kettle soap has its excess alkali salted out and drawn off before framing, so the recipe states the alkali charged, never the alkali the bar keeps. Read as a modern cold-process recipe it would be lye-heavy.
What the numbers say
Computed from the fatty acids of the fats above. The bands are what the craft has settled on, not chemistry — a bar outside one is not wrong.
The source
OCR DOUBT, not a transcription slip: these three sum to 2,350 under a printed total of 2,250. The other three French formulae sum exactly, and 1,575 is one damaged digit from 1,675, so the book most likely printed 1,575 — but the figure here is what the scan says, flagged, rather than a correction we invented. Watt: "Produces a very hard soap, of good quality, but not so white as the above. It turns slightly yellow by keeping."
Read from the Internet Archive OCR of the Cornell University Library copy. Page numbers are taken from OCR'd running headers and may be one out where the header digits were damaged.
Read from a scan rather than a proofread transcription, so the figures are checked against the book’s own printed total where it prints one.
