Testing for salts in pottery.

Post by Barnadet.

This pottery jar with a spherical shape has a circular base and brown stripes on the body (registration number IM222239 – Iraqi Museum).  I worked on testing for soluble salt by using distilled water after taking a sample from the jar.  I put on the sample a drop of nitric acid, then a drop of silver nitrate.  The result was positive so the jar contains chloride salt.

Dropping silver nitrate on the sample to test for chlorides.
