"About the same time, a French chemistry
student called Charles Sauria produced the
first �strike-anywhere� match by substituting
white phosphorus for the potassium chlorate
in the Walker formula."
Could you clarify what was substituted with what?
What was the first chemical ingredient and which of those two came after? |

Potassium chlorate was used first and then followed by white phosphorus.
