ocean sediment glazes

Joan Lederman

is a very good friend and first class artist potter

As for as ceramic sites go this is a totally unique.

She collects and mixes geological specimans from deep

under the oceans of the world.

These are applied to beautiful forms and the sources are

documented. Joan inscribes each piece with the longitude,

the latitude, and the depth of the sea mud sample.

see her gallery, descriptions and store

I strongly recommend
