[00:19:03] Quartz grains survive much better because they're so hard. So that's why there's so much quartz sand around. So quartz sand is the stuff that we really, that we need, that we use the most of. And then the main differentiation when it comes to how we use it is the level of purity, how much the purity of the quartz in that sense.
