Hi everyone again Paraffin for you in the US is paraffin wax as one of you rightly said. Over here in the UK paraffin is a liquid that used to be used for heaters, lamps and oil burning egines, and sometimes still is. Paraffin oil may be what you would call kerosene (or kerosen para ti Guillermo). Paraffin oils have a boiling point in the range of 150 - 300 degrees Centigrade while the wax has one between 50 and 60 degrees. Paraffin wax is used for all sorts of things includeing cheap candles and waxed paper. Entonces, parafina es kerosen y se deberÃa poder comprar facilmente. translation, paraffin is kerosene and should be easy to buy Camphorated oil on the other hand I would suspect is not strictly necessary. The oil part yes, but the camphor part was probably used as a preservative as some of you may remember camphor balls or mothball ususally consisting of napthalene and sometimes, yes you've guessed it, camphor. Therefore, camphorated oil was probably used as an amplication for preseving perishable non edible goods in the days of moths. Now all of this is some educated conjecture but I hope it is of use to you. I would think that oil would be sufficient. I am just looking up in a dictionary that camphor itself is a whitish, translucent crystaline, pleasant-smelling terpene ketone, whatever that means except that most ketones smell nice from what I can remember at school, used in medicine and in the manufacture of celluloid. Ah ha! There it is, the manufacture of celluloid. Is that not what one is doing when applying the camphorated oil to the paper with paraffin? Probably not. I hope I haven't confused things too much hasta luego Alexis
