* Lightning can heat rock to more than 3,000-F ( 1,600-C)
* The boiling point of quartz rock is 2,230-C.
* As quartz 'steam' adiabatically cools to 2,229-C upon rising, it returns to liquid lava droplets, and at approximately 1,650-C would solidify to a quartz particulate aerosol.
* It appears that lightning would need an additional 630-C temperature increase in order to just get rock 'vapor' into the atmosphere.
* An electric arc welder generates 6,500-F. Welding vapors are not at escape velocity, and remain at Earth.
