Can you attach real sea shells on ceramic pottery then fire it?
Question: I want to make a vase with real sea shells on it from the beach. Is it possible to attach them then fire them in the kin for bisque firing then again for the final glazed firing?
Answer: Not that I'm aware of... but I've never tried it. There are two potential problems when firing foreign objects in your pot.
One, is shrinkage rates. The clay might shrink at a different rate than the sea shells causing something to break or crack. If you tested the the shrinkage of a particular sea shell you could theoretically solve that problem by finding a clay with a similar shrink rate.
Two, is firing temperature. Put simply, your sea shells might melt or burn up at high firing temperatures. Again, I've never tested this, but it's a concern.
Any one out there tried using seashells? We'd love your input.
See some great pottery by Mark Anderton
with agates fired into them (at least I think they're fired in....)
Thanks for the question,
