Pumicing stones?

Is there an article for the use of pumice or other stones for use in wearing down calluses? Since pumice is so often used for this, I think it would be good to interlink the topics. Thoughts? Tyciol 05:41, 6 June 2006 (UTC)

Yes why not you can use acid cellouse enzyme for the same kind of result and you can save your garment from tearing and gating damage from the stone wash

Would this stone wash have a role in medicinal history? If it did, I guess it should be noted in this article.Slartibartfast1992 01:23, 28 November 2006 (UTC)

Pumice is and was used as an abrasive material for many purposes and over many periods of time. I added the origins of beauty uses for the stone, and the topic is linked to pedicures. I also added medical history. Stephbender (talk) 23:17, 8 April 2019 (UTC)

History of pumice use

Does anyone have any idea when pumice began to be used to remove dead skin/abrade feet etc? Did Victorians use pumice for such purposes? Was it commonplace in well to do Victorian homes?

is it possibly mixed with clay? — Preceding unsigned comment added by 122.52.143.17 (talk) 01:07, 13 February 2014 (UTC)

I added multiple uses for pumice, history included. The Egyptians were the ones who started the trend to remove hair using stones and Chinese used the stones for nail care. No exact origin of use can be determine because it was so long ago and pumice stones were so commonly found on the surface all around the world.Stephbender (talk) 03:08, 10 April 2019 (UTC)

Found

Where is this rock found? Im doing this for an assignment and maybe im not looking hard enough? —Preceding unsigned comment added by 207.118.211.222 (talk) 22:04, 26 November 2007 (UTC)

It is an igneous rock so it is probably found by any volcano. Nutty Gorilla —Preceding unsigned comment added by 70.111.49.163 (talk) 03:32, 4 March 2008 (UTC) the pumice stone is from volcanoes which in most cases is shot from the top of the volcanoe and cools from liquid magma the pumice it was been recorded to reach speeds of 400km an hour. in many eruptions scoria is all so formed this is used for our paths and walk ways.

>>Added a section for where pumice is found. Please add locations which are legal for mining. Avoid protection areas such as U.S. National Parks. SWP13 (talk) 04:05, 12 October 2018 (UTC)

I added sections were pumice can be found on each continent. Pumice is ejected from violent volcanoes, similar to opening a pop can the bubbles expand, in this case the magma is gaseous and hardens with air pockets. Not all volcanoes erupt explosively like this, therefore not all volcanoes produce pumice. This explanation is described in the article with links to other Wikipedia pages for a deeper explanation.Stephbender (talk) 03:15, 10 April 2019 (UTC)

Buoyancy

Is it the ONLY type of rock that floats? If not this is a common misconception. Zarano (talk) 02:33, 28 June 2009 (UTC)

Pumice is the only rock that can float, scoria has similar vesicular properties that are defined in the article however scoria does not float.Stephbender (talk) 03:10, 10 April 2019 (UTC)

Pumice

pumice is a extrusive rock it cools very rapidly. —Preceding unsigned comment added by 67.191.151.149 (talk) 22:39, 1 October 2009 (UTC)

Image not actually showing processed pumice?

I removed the image "File:Pumice On Plastic.jpg|A piece of processed pumice resting on a plastic bag."

A piece of processed pumice resting on a plastic bag.

from the gallery. I think it shows a commercial product of a foam material resembling the properties of pumice, and I can imagine the product is called "pumice stone" in the context of cosmetics. If it does indeed show a processes sample of pumice, it could be put back with a detailed explanation how it was processed, and for what purpose. Volker Siegel (talk) 21:23, 1 May 2015 (UTC)

Melting point

For practical purposes I was investigating if there were any given melting point for rock or powdered pumice. The samples Ive seen is uniform enought to believe it would have a universal decomposition and melting point, but I am not a geologist.

I also would like to have a more specific explanation of the constituents and the respective amount of the most widely used and found floating upon shores. — Preceding unsigned comment added by So Calle H (talk • contribs) 06:07, 7 December 2017 (UTC)

Kutkhiny Baty

this has a few more pictures of Kutkhiny baty and a bit about where the name came from, is it worth a stand alone stub, or should pumice rafts, and this outcrop get more expansion in the article ? EdwardLane (talk) 06:51, 3 July 2019 (UTC)

Probable copyright violation

A probably copyright violation was introduced with this revision. The material added appears to a word-for-word copy of the cited source. I've removed this pending more thorough investigation (Is the article somehow in the public domain? Was the author himself the editor who introduced the material? Citogenesis?) --Kent G.
