Electric slow cookerVery popular in the United States, the slow cooker, better known under its registered name, the Presto pot (Presto® is a registered mark; visit http://www.gopresto.com), is used by lots of candlemakers on the other side of the Atlantic ocean.
What makes it so attractive is
In the United States, the Presto Pot® can be easily found almost everywhere. But if you live in Europe or, anyway, outside the US, finding a Presto Pot® or an equivalent won't prove easy!
The closest I've found (bottom picture) is a slow cooker sold by a UK Internet shop. It could do the trick IF ONLY it had a better temperature control.
You could possibly use it to melt a bunch of paraffin but you would have, once melted, to transfer it to a double-boiler for a more precise control of wax temperature.
If you think you've found the solution by ordering a Presto Pot® from an US webshop, think again:
To make a long story short, if you're not a US resident, you'd better choose the good ol' double boiler with a choice of inserts or go for a dedicated wax melter.
You can use your Presto Pot® to melt up to 8 pounds of wax in one batch and, if you're a little handy (or have a handy husband), you can modify a classic Presto Pot® and turn it into a full-featured wax melter, complete with spigot to dispense the molten wax (much easier than using a ladle!)
Candletech has a very interesting article, fully illustrated, that explains how to modify a Presto Pot to this purpose. Click here to view the article.
