Back to 'Ice' for a sec - the more I think about it the more over complicated my idea feels - possible, but a lot of faff creating the right shaped outer mould to pour the resin into and around the figure.
How about clear acrylic 'Crackle' or 'Krakelee' medium?
It dries clear with a 'cracked porcelain' type effect. Not used it myself but my wife and daughter used to use it for weird art/craft projects. I've 'borrowed' some and am working on a test on a white undercoated blank base at the moment - if that works I'll try it on a gash figure (god knows I've got enough of them
) and maybe post the result if not too naff.
