Ideal for 5 gallon metal pails. It heats up to 200 degrees, which is enough for paraffin and wax, which provide a high concentration of fragrance. I work primarily with paraffin and it melts great and has good fluidity at 200. It doesn't get hot enough to ever have any concerns about wax decomposition or reaching flash point. It was just what I needed to take my hobby to the next level by increasing production. The blanket is quite thick and durable. It's nothing to worry about or coddle - it's like duct tape and it's very thick. I highly recommend this product to candle makers looking to increase production.
