Hi guys, I am fairly new to candle making and I was finding it a hassle to melt my wax over a double boiler every day and my housemates were getting annoyed with me always using the kitchen for this purpose. I have seen a lot of people using a buffalo soup kettle to melt their wax and it is supposed to have a max temp of around 200°F/ 95°C. I have put my wax in and turned it on and I kid you not it has taken around 12 hours to get to temperature. This cannot be normal or functional for people who make candles. Can anyone who uses one please give me some trouble shooting tips as to how you get it to work effectively for you? :) Many thanks, Kaya
