I really want to do some gumprints but it's very hard to get the Ammonium/pottasium Dichromate to do it. I myself live in Belgium and asking in a pharmacy is like asking explosives from a cop. So I wonder where to get it in Belgium or Holland (Holland is closeby for me). Anybody an idea?? Most online sellers won't ship internationally and I don't have a Creditcard to pay them if they are not in the Eurozone.
