In general, pumice will float. There is enough trapped air in pumice that it is buoyant.
Floating rocks: pumice. Non-floating rocks: all but pumice. Pumice can float on water because its density is so low, due to trapped bubbles of air which formed during its solidification from lava.
Burnish, scour, rub...
Any with a density less than the fluid into which it is placed. Pumice is a volcanic rock that will sometimes float on water.pumice
A pumice rock is considered a rock because it is composed of multiple minerals, mainly feldspar and quartz. Minerals are the building blocks of rocks, so pumice is classified as a rock rather than a single mineral.
The streak left on the streak plate by rubbing a pumice rock usually appears white or colorless. This is because pumice is a light-colored rock composed of volcanic glass with a frothy texture due to gas bubbles trapped in the rock, causing it to create a light streak when rubbed on a streak plate.
Pumice, being a rock composed of possibly a number of various minerals, does not have a streak color as such. Powdered pumice would reflect a combination of the streaks of the constituent minerals.
Pumice can be white, gray, or even pink.
