Glued-up soap, kettle stock
This one names a fat the database does not carry yet, so the numbers below are not computed. The fats a recipe wants and we lack are what decides which ones get added next.
The oils
| Oil | As the source prints it | Share |
|---|---|---|
| Palm Oil | Bleached palm oil · 5 parts | 41.7 % |
| Distilled grease · not in the database yet | 2 parts | 16.7 % |
| Cotton oil foots stock, 63% fatty acid · not in the database yet | 1 parts | 8.3 % |
| Rosin | 4 parts | 33.3 % |
How it is made
| Process | Full-boiled |
| Alkali | Not stated |
| Superfat | Not stated |
| Water | as the source states it |
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
This one cannot be computed yet: it names Distilled grease, Cotton oil foots stock, 63% fatty acid, which the ingredient database does not carry.
The source
A deliberately cheap soap: the fatty acid content is then run down to 50-55 % in the crutcher with silicate and carbonate.
