Is mixing powdered zinc and sulfur at room temperature a chemical change?

Zinc and sulphur aren't likely to react when mixed carefully at room temperature. Therefore, there is no chemical change. The most likely reaction is the oxidtion (tarnishing) of the zinc which will react slowly with the oxygen in the air.
I can't remember whether this mixture is part of an industrial process, but I suspect that if you also mix in an oxidant like saltpetre, you might cause an explosion.
