I agree. Thats why it's important to explain the context in any
analysis of chemical reactions. If reducing a liquid in a pan
containing aluminum potassium sulfate the anhydrous residue will
'survive' - but if it was deposited in/on a potsherd this residue is
unlikely to survive deposition because of its solubility.
