I have only used METAL pouring pots, but I need something larger (not a commercial melter), will a plastic bucket work. Ha sanyone tried adding a spicket to one? I dont mean the buckets you used to wash your windows with I mean the large ones that paint comes in, like this http://www.europeanglass.ca/Commercial/Paint/Images/large_paint_buckets.jpg Im thinking that I would have to have a different bucket for each scent, im sure that there will be some residue in the cells of the plastic.
