Kelly in AK Posted May 14 Report Share Posted May 14 (edited) It is coincidence that @davidh4976 mentioned a clay body so high in iron that a magnet will stick to it and I received in the mail today the strongest magnets I’ve ever seen. So, of course I had to play.. My clay is a local iron rich earthenware that vitrifies at cone 03. Not all the pots do this, apparently only the ones that are reduced heavily and fired to maturity.

Well, can you show the interior? Looks like a Min glazing technique.:-))) Rae Reich and Kelly in AK 2 Quote Link to comment Share on other sites More sharing options...
Russ Posted May 14 Report Share Posted May 14 In reduction the oxygen in the iron oxide is removed leaving the pure form of iron FE. Ive done heavy reduction on pieces sprayed with straight iron oxide and come up with a silver gray finish.

Kelly in AK Posted June 1 Author Report Share Posted June 1 No trickery here, just a very strong magnet. I’ve since played some more to find the oxidized pots do it, the greenware does it, and the wet clay does it. All will attract a magnet. Some very weakly, others vigorously.

PeterH Posted June 1 Report Share Posted June 1 1 hour ago, Kelly in AK said: No trickery here, just a very strong magnet. For clarity, I assume you are talking about Neodymium magnets. I remember my shock when I first met them, they are qualitative different from traditional magnets aren't they. But quite cheap and freely available on ebay etc. H&S warning. When swallowed they can seriously damage the stomach (especially by pinching the stomach wall between them). So keep them well away from children. https://rcem.ac.uk/wp-content/uploads/2021/10/RCEM_BPC_Ingestion_of_Super_Strong_Magnets_in_Children_170521.pdf Quote Link to comment Share on other sites More sharing options...
Kelly in AK Posted June 1 Author Report Share Posted June 1 Yes, they’re neodymium, from United Nuclear, the most powerful magnets I’ve ever seen. Your warning is well placed @PeterH, I don’t have any kids around and these things still scare me. I used the word “play” loosely. Not toys.
