This is a small SEM Nano Gigapan of some volcanic glass given to us to image by Ronald Schott a Geology professor and avid gigapanner. This type of volcanic glass forms a lattice structure, and is not very dense. Hopefully Ron will talk more about it in a comment:)
This gigapan is composed of 42 images.

This is an example of reticulite, a rare type of pumice-like lava that is so gassy that the bubbles actually merge with each other leaving lava to solidify as volcanic glass only along the edge and corner intersections of multiple bubbles. Whereas pumice floats in water because the gas bubbles are isolated from each other, reticulite will actually sink in water despite its much lower overall density because the bubbles are connected and water can permeate through the entire structure. This sample probably originates from the 1983-1986 high fountaining eruptive episodes from the Pu'u 'O'o vent along the East Rift Zone of Kilauea Volcano on the Big Island of Hawaii. You can learn more about reticulite and see a picture of a macroscopic piece of it at: hvo.wr.usgs.gov/volcanowatch/2007/ 07_09_06.html
