If my memory of O Level chemistry classes is anything to go by, the
idea was that you used a piece of Magnesium ribbon to ignite it. I
don't recall Manganese Dioxide being part of the recipe.

Anyone have advice on making thermite? Ingredients, sources, proportions?
The internet seems to think that just using aluminum powder with ferric
oxide is relatively hard to ignite, and that some manganese dioxide would
help with that.
Without spending too much time shopping, it looks like I can get:
* aluminum powder, 5 micron, 2 lb for $34
* ferric oxide, 10 lb for $27
* manganese dioxide, 1 lb for $39
