I experiment with thermite to determine the rate of reaction. Thermite powder is burned in a pyrex tube and filmed from the side, so the reaction front can be seen moving through the powder. I was amazed at how slow the reaction progressed - It's extremely dependent on the container. Based on the results I observed, I would expect the fastest achievable reaction would be loosely-packed powder in a large and low-aspect-ratio thermally insulating vessel like a flowerpot.
