This is some really good information about why a Presto Pot is so beloved when making candles. Note: this information has been copied directly from the Candle Cauldron website at this address: http://www.candlecauldron.com/prestopot.html What is a Presto Pot? If you're a candlemaker looking for an easy and inexpensive way to melt your wax, Presto Pots are a great way to go! They are called Presto Kitchen Kettles, and you can find them at your local Walmart, Kmart or Target stores for around $20 each. They will hold approx. 6 to 7 lbs of wax, and they melt nice and quick... about 20 minutes and you've got a full batch of wax melted and ready to go! They are made of a thick metal with a non-stick coating, so they clean up real easy... just wipe out the wax residue with paper towel while the pot is still hot (careful not to burn your hand, I wear gardening gloves!). If there seems to be any scent leftover in the pot, try wiping it out with a baby wipe (very handy!). The pots have a temperature dial on them, so you can set your pot to an exact temp, not just low-med-high like on a crock pot. But you still need to check your actual wax temp with a thermometer because the wax inside can be a different temp than what you set the dial on. Since these pots have a concealed heating element, you can melt wax directly in the pot without having to use water and a second pot inside like a double boiler. The trick is getting your melted wax out of the pot and into your pouring pitcher. Some people prefer to pick up the pot by it's handles and dump the wax carefully into a pitcher. Others prefer to use a ladle or a pyrex measuring cup to scoop out the wax and transfer it into a pitcher. Or another alternative is to install a spigot or faucet onto the pot. This of course involves some know-how and a little more work, but some people have found these to be very handy.
