34. TIPS AND HINTS

Clay used for ceramics is roughly of two kinds:

- stoneware (grès) of high density and non porous, fired at 1300° Celsius;
- earthenware (faïence) more tractable and porous, fired at 1000°.

This last one remains a little porous even with a good glazing. Certainly, the bottom of pots is glazed with great care, but, even then, an earthenware pot still oozes a bit when you fill it with water. Awkward. It leaves marks wherever you put it.

A remedy?

I heard that you had to fill the said pottery with milk and let it stand for a few days. The particles of 'curdle' slyly filter through the minute pores of your ceramic and make it waterproof.

True, it works!
If you don't believe me, try it!
