Detachable torch heads with disposable butane canisters will be sufficient for this course.   These should be Sterno (or comparable) heads paired with collared butane canisters that are NOT refillable.  Please note that small culinary torches like Blazers may not produce enough heat for this project.  Dual fuel and larger torches such as the Smith Silver Smith and Little Torch, and comparable systems, will work as well.
