The melter is maybe the essential most basic tool for soap makers. Of course you can use ordinary home appliances for melting, but a proffesional melter is best for that perpose.
Here's an example from soapwizards.com:
Melters - Find it yourself or buy it from us. The first tool most soapers will need is the melter. We find that the electric roaster is ideal for most starting M&P soapers. It holds 4-1/2 gallons of soap, has no hot spots to burn the soap, and runs off household current. A great way to start. When you are ready to enter the big leagues, we also sell 10 gallon, 25 gallon, and 70 gallon, professional, water jacketed melters. We think ours are the best and the least expensive.
