I have always made it a point to use only natural and safe materials when producing my work. There are no toxic materials in my clay, glazes or firing process. No Lead, No Barium, nothing toxic. Particularly considering that my studio is next to my children's bedroom!
I am careful to reduce dust and use a dust mask wherever necessary (special thanks to Phil Rogers for sending me a Dust Mask from the UK that didn't bend my nose over like the Japanese ones do!), and I use eye and ear protection where appropriate.
I have therefore always known that my products were safe for the consumer. This has always been a primary concern for me.
However, in order to sell my work at Mitsukoshi Department store I had to have my work tested by a public authority to prove it was safe for use with food. This is now necessary for all ceramics imported into Japan, and will apparently become standard practice by law for local production as well in the near future.
So, I sent my work to the Tajimi Ceramic Institute for testing and received this certificate proving that my work is perfectly safe for use with food. You no longer have to take my word for it!
