Yes. Pumice is defined as being highly vesicular.
it has holes in it and has kelfrigis
Pumice
Pumice is a type of volcanic glass that contains holes caused by pockets of gas trapped during its formation. These holes give pumice a lightweight and porous texture, making it commonly used in beauty products and as an abrasive.
Pumice is less dense than scoria. While they both have holes, pumices pore like holes trap air allowing it to float.
pumice
Pumice forms from globules of lava that are full of gas bubbles. Those bubbles are still present when the lava solidifies.
colorless or light gray.
In rocks such as basalt, scoria, and pumice the holes are formed from gas bubbles that were escaping from the molten rock as it cooled.
Pumice is full of holes called vesicles formed from gasses escaping the molten rock. The holes greatly reduce its density.
The brand of hand soap called "Lava" is alleged to contain pumice. Lava soap really does have pumice in it.
Its porous, full of tiny holes and it floats.
I'd say pumice is the closest to your description.
