The method ordinarily pursued is... A large Quantity of water, from One thousand to fourteen hundred gallons, in which have been dissolved about thirty-six pounds of oxalic acid, is heated to boiling. In to this liquor one ton of dried pomace is placed and the whole stirred while the heating continues. After one hour of treatment in this liquor the liquid is drawn off and at once evaporated to separate the cream of tartar there from in its crystallized form.
...Enough of a calcium salt in solution is subsequently added to precipitate all free oxalic acid[1]
This translates to roughly:
For each kilogram of pomace, dissolve 18g (0.2M) of oxalic acid in 40 to 60L of water, combine it with the pomace. Boil for one hour. Filter, and evaporate the filtrate to produce crystals of potassium bitartrate
- CaC4H4O6(s) + C2H2O4(aq) → CaC2O4(s) + C4H6O6(aq) // Insoluble calcium tartrate converted to insoluble -oxalate and free tartaric acid solubilized
