620. Pottery Jar (broken) - contents of

This contains a quantity of brown material intermixed with white,
the white being largely in the form of star shaped crystalline
masses.
It has only been possible to make a partial analysis on account
of the lack of the necessary re-agents.
Common salt
Sulphate
Alkaline carbonate (i.e. potassium or sodium carbonate)
Tests negative

The crystals consist of some carbonate (though not potassium or
sodium carbonate) but without other reagents it has not been
possible to determine what the carbonate is.

Tartrate (typical of wine residues) appears to be absent or, if
present, only in very small proportion.

Complete analysis to be made in Cairo.
