Untitled[edit]

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[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[edit]

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[reply]

Polymer gels versus low molecular weight gelators[edit]

Many of the definitions on this web page are specific to polymer gels. For example, cross links are not a requirement for low molecular weight gelators. Does anyone have have thoughts on this? I think that the page should be renamed or expanded to include LMWGs.Klsyking (talk) 02:31, 13 April 2011 (UTC)Reply[reply]

About gel and baldness[edit]

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. —Preceding unsigned comment added by 222.127.47.40 (talk) 10:08, 21 December 2008 (UTC)Reply[reply]

Why is the sound induced gel section included? It includes too many specific details in contrast to the rest of the article, and it does not seem to have many citations. —Preceding unsigned comment added by 142.150.227.231 (talk) 19:43, 20 May 2009 (UTC)Reply[reply]

Gels versus water[edit]

I have found a herbal substance that works in water but not in gels or lotions. The lotions we have tried are lanoline, silicone oil, petroleum,and other gels which sometimes contain 7% water. What is the difference? How can something work in one but not the other.

Thanks,

Crystal Soil - Water Pearls[edit]

I think this should be added in the uses of Hydrogel: http://www.crystalsoil.com (the website is only an example, there are many producer for this product. --77.186.131.47 (talk) 11:51, 31 March 2010 (UTC)Reply[reply]

Continuous/discontinuous phase - mistake?[edit]

According to the last sentence in the lead, …the solid is the discontinuous phase and the liquid is the continuous phase. This contradicts the the table in Colloid#Classification_of_colloids, which says that for a gel the solid is the continuous and the liquid is dispersed. I checked in my chemistry textbook agrees with the Colloid article. MYCETEAE - talk 07:41, 13 April 2011 (UTC)Reply[reply]

I agree. That needed to be fixed, so I did. Devil Master (talk) 12:51, 22 May 2011 (UTC)Reply[reply]
Actually they might both be continuous! -Johannes 13.7.2011 — Preceding unsigned comment added by 80.248.102.76 (talk) 18:11, 13 July 2011 (UTC)Reply[reply]

Hard gels?[edit]

I asked at Talk:Silica_gel#Gel.3F, but maybe this is a better place. By what definition is silica gel a gel? —Ben FrantzDale (talk) 13:33, 24 April 2012 (UTC)Reply[reply]

Vegan[edit]

I think it should be mentioned on the lead whether gel is vegan or not.—‎Lost Whispers talk 12:41, 4 June 2017 (UTC)Reply[reply]
