The Arabic Origin of Summa perfectionis magisterii
And the Other Geber Latin Works
Calcinations by Fire Only or By the Acuity of Salt
a short note
We continue our search for similarities between the texts of Geber’s Summa and the other Geber Latin works and between the Arabic works of Jabir ibn Hayyan. This is another important process that is described in similar terms in both the Latin and the Arabic texts.
Geber, Summa, Russell’s translation, p. 103
For soft Bodies have one General way, according to the Intention of Calcination, viz. that both may be calcined by Fire only; and by the Acuity of Salt prepared or not prepared, both likewise.
Jabir, The Book of Seventy, Kitab al-manfa’a, Sezgin p. 361, Lory p. 159 
Then its calcination …in preparation is done in two ways and two paths, one by burning in fire and the other by corroding with acute and salty corrosive materials.
