1. The light-weight rock froth itself is quite familiar, and turns up in British bathrooms; it is, of course, pumice.
2. Pompeii was not the only town to suffer from the rain of pumice and ash; the fall-out in fact covered an area of hundreds of square kilometres and several other Roman settlements, but Pompeii was particularly badly hit because it was so close to the volcano and was down-wind of it, so that the ash-laden eruption cloud was carried towards the town by the prevailing wind.
3. The whole of the northern part of the island of Krakatoa had disappeared, with the exception of a bank of pumice and a small isolated rock, about ten metres square, which was left standing above the ocean with deep water on either side.
4. Some of these mudflows rushed through Herculaneum and engulfed it completely; crushing some buildings and smothering the rest twenty metres deep in a slowly consolidating welter of mud, pumice, boulders and debris.
5. The hardest, pumice, is used in a number of proprietary compounds.
6. Pompeii, approximately eight kilometres from Vesuvius, was buried over three metres deep in pumice in A.D. 79, and the total volume ejected in the forty-eight hours or so of that eruption was probably about three cubic kilometres.
7. It almost disappeared under a carpet of pumice over three metres deep, so that only the upper parts of some tall buildings emerged above it.

10. This was in a state of semi-continuous eruption, with minor explosions taking place every five or ten minutes, showering fragments of pumice 200 metres into the air, and occasionally revealing the cherry-red glow of liquid lava in the crater, while all the while a great banner of steam rose 3,000 metres into the air.
11. At 11 a.m. a heavy rain of ash was falling, and by 11.20 the air was so thick with ash and pumice dust that the sun was blotted out, and total darkness fell on the city, remaining until 1 p.m.
12. It is hard to imagine a greater contrast between two rock types than that between obsidian, a natural volcanic glass which will shatter at a blow into razor-sharp splinters, and pumice, a rock so light and frothy that it will float on water.
13. There are some reports of a major eruption which took place between May 1680 and November 1681, and this eruption is said to have stripped bare the rich vegetation and ejected vast quantities of pumice that covered all the surrounding seas, but this is all that is known.
