There is one supplier (Candle Creations) in the city I live in and that's where I got started. They sell paraffin and beeswax, block dyes and a few fo's plus 15 and 30 ply flat braid wick. All their moulds are plastic. I then found 2 suppliers (Stacks of Wax and Aromatherapy in the Raw) in another state who also have paraffin and beeswax, a bigger range of wicks and fo's and one of them has the little diamond dye blocks that I love because I can duplicate colours. They also have pillar moulds but no aluminium seamless. AND just the other week I discovered a new supplier Natural Candle Supply) - also interstate - who are importing fo's, dyes, waxes and moulds from the good old USA (not sure who). Yippee, I've now got some seamless aluminium moulds, including votives (and wick pins) and in a couple of weeks' time they'll also have palm wax and additives (they also have soy wax). BTW, the only additives I've found so far are stearine and vybar (tho' not sure what type of vybar). This new place also has tons of dye to choose from AND in 3 different types; block, diamond and liquid - WOW! Sorry that I'm raving on, this is probably a case of too much information, but you did ask. There may be other suppliers around but I haven't found them or else they specialse in beeswax or plastic moulds.
