granitic lava formed when you melt QRTZ and PQRT, has a very thick flow, and would fall slowly. the glow would be not as bright as normal lava, instead a dull red flare.
or it could behave the same kind of way was when the ctype of ice is lava
with ambient heat on, the lava cools slowly, and when it solidifies, forms QRTZ with a tmp of 3, but only as long as no elements like LN2, LOXY, FRZZ, WATR, CFLM, or anything that cools it quicker touch it.
