Hi All, Speaking of raku, does anyone know where ferric chloride can be obtained? I'm getting ready to get my own raku kiln and I like the brown highlights spraying ferric chloride on horse hair pots gives. I looked in all my pottery supply catalogues and can't find it. I was rakuing at friends and hers was bought at Radio Shack. I called them and they have stopped selling it. I know it has to be handled very carefully but I need some for the results I am seeking. Or is there a substitute chemical I can use? I live in the northern Shenandoah Valley area of Virginia, USA. Thank you for any information, Sandi

Hi Sandi,
That's right - ferric chloride is no longer used to etch printed circuit boards - they now supply ammonium persulphate, which is of no use for your purpose.
Wouldn't ferric oxide do the same thing? Whether it's the oxide or chloride, the iron should still give the effect.
