Chinese Trans Green

Anyone had problems encasing tuffnells trans green?

Not the transparent green but the imperial green isn't keen at all, got some lovely crazed marbles with it!

Hi,
      Not transparent Green but as Lotti says the Imperial Green doesn't like it too much.

Best wishes ,

Are you encasing it with something else? Also are you leaving it to garage for a long time? I've not really encased it very much, but not had any problems with it on the back/outside of things so far.

Imperial green though I use with great caution, I suspect its a based on a chromium oxide formula, which can cause problems when the chromium colours are left to garage for a while they can release some chromium gas which is fine if it can escape, otherwise it causes area of different COE (I think if memory serves me right 54-55) which is why some chromium colours and some aventurine colours that use flecks of chromium cause cracking and crazing.

Encasing with clear... Think I will pull it down with clear just to be on the safe side
