There are two key differences between what would be quartz and pump.
1. Quartz is destroyable; pump is not.
2. Quartz would release a constant pressure at a pre-set value. Pump's pressure depends on temperature.
Regardless, the quartz spark one isn't one I particularly care about. My real favorites/ the ones I want to see happen the most are the gunpowder and the thermite recipes.
