Well some experiments over the weekend using my IR thermometer seemed to show promise..
I used my electric top oven and the thermometer was showing 280degC tantilisingly close to the correct temperature (I'd settle for purple). I put two plates in the oven. One went dark brown the other didn't change at all?? I later realised i'd bought stainless steel, two plates made of mild steel and two of stainless steel - doh.
I then used a soft flame on the 'browned' steel and got a reasonably even blue(ish) colour. So one plate done another to go :)
