This stainless steel double boiler insert is an indispensable tool for any DIY cosmetic maker, candle crafter, or soap maker who works with heat-sensitive ingredients. Designed to sit over a pot of simmering water, it provides gentle, controlled, indirect heat that melts waxes, butters, oils, and chocolate evenly without scorching, burning, or overheating your materials. Durable, rust-resistant, and easy to clean, it’s a simple yet essential addition to any maker’s workspace.
