I find I have trouble when I encase it. Tends to crack, so I wonder if I'm just not treating it gently enough, of if it's slightly incompatible like Special colours.
It also likes to web like intense black if you dab it onto a soft colour and super-heat it.
I like to mix it with copper (cool opaques) colours and super-heat. It causes some wild concentration/webbing effects. It also does cool stuff with EDP. If I use it with Ivory I only heat it a little, 'cause the outline reaction can get out of control very quickly.
Hope this helps! It's the prettiest richest green out there, just veeeery reactive.
