...it just dawned on my that you're going to polymerise the gum with 
bichromate which is of course going to make it insoluble in water. Your 
possibilities for using an etch then broaden (I'd try high strength 
hydrogen peroxide maybe). How do you remove the hardened gum after the 
etch though? ~m
