Amazing. Thank you, Frank. Would the chemical in the pestle be manganese? I wonder how the shop mentioned at the bottom of this page (http://www.patternglass.com/sunpurple.htm) is irradiating their stock?

Pestle, yes.

I think the brown colouring is a bit more disturbing than the purple - as that is well known now. I presume that the purplers have had some results on lead crystal, even if unexpected, but I have not heard of it. Where does one get the Cobalt 60 needed?

A hitherto unheard of destination for those ex-Soviet nuclear warheads that have gone missing  ;D Either that, or they can take their place in the queue behind the terrorists waiting for more cannisters to fall off Schlumberger trucks in Western Australia... http://www.crikey.com.au/Politics/20070117-WAs-missing-radioactive-canister-the-plot-thickens.html
