Talk:Gel

There was some back and forth reversion of revision 236499516. I want to clarify the purpose of the edit and why it was reverted by an automated spam catcher. An incorrect conclusion was drawn from a scientific paper regarding gellation as a phase transition. I added a DOI link to the article, and while I was there, I corrected a formatting error on an external link (which turned out to be a commercial site, and likely spam.) This caused the bot to think I added it. I've added only the correct link in edit 236551270. This IP is no spammer; check my contribs. 128.138.120.79 (talk) 23:44, 5 September 2008 (UTC)[reply]

I wouldn't agree that the type of gel used in fibre optic cables resembles petroleum jelly in viscosity. The gels used for this application are typically similar in consistency to soft "hair gel", and are comprised of synthetic hydrocarbon oil gelled with either colloidal fumed silica, or various synthetic rubbers. The viscosity is highly dependant upon shear rate, and these materials do not "melt" as such. Petroleum jelly is solid at room temperature and melts at temperatures above about 70°C to form a Newtonian fluid.

Clean-up

This page requires a clean-up or total re-write. Before I start, does anyone have any thoughts about what they'd like to see?

It is SUCH a broad subject... I was linking to it from my rewrite of Stress ball to describe the different densities of gels used in physical therapy. --Mdwyer 17:29, 8 April 2006 (UTC)[reply]

About gel and baldness

There should be mention in this article about one of the possible effects of using gel regularly, which is the thinning of hair and possibly baldness.
