make a small piece, put it in a little saucer made of stoneware clay,
and fire it to your stoneware temperature. If it melts, it's earthenware.

John,
I am very grateful, thank you for the advice. I will have a go. I am not
sure what I should expect to see. The total number of pots are 4 so I
suppose I can experiment with two of them.
Thank you again
Hani

All you need to do a test is a tiny bit of clay. Roll it into a ball and
fire it (on a bisque tile or other shelf-saver) to cone 6. If it is
earthenware, it will melt into a flat blob at that temp.
