Talk:Sodium silicate

message: Sodium Metasilicate redirects to this page, but has very different properties.  It requires its own page.  For a brief comparison see http://www.finishing.com/155/96.shtml.  Can someone get that page started please?  The text of this page should also be changed to reflect that these are not the same.  On a (closely) related note, the silicic acid entry needs improvement, stats, pics, etc.

replies: text: Sodium silicate commands a 50 to 100 percent price premium over sodium hydroxide, and processors need the equivalent to 0.5 to 1 percent of it to the volume of crude oil as a neutralizing agent, depending on the acidity of the vegetable oil.

message: I've noticed that my dishwasher detergent containts sodium silicate.  This should probably be worked into the article.

replies: text: Another major ingredient in dishwasher soap is sodium carbonate. My intuition is that the common ion effect, from the dissolved silicate ion of sodium silicate, should help reduce the attack by sodium carbonate on glass and glazes. I would appreciate a correction if I am wrong. --AJim (talk) 16:58, 30 May 2011 (UTC)

message: A friend of mine tried to use sodium silicate as an antifreeze in his car (prehaps misunderstanding its use as a cheap stop-leak compound).  The stuff solidified while in his radiatior, requiring a complete cooling system replacement.

message: Na2SiO3 does not contain discrete SiO32- ions- with VERY rare exceptions silicates contain 4 coordinate Si and in the case of Na2SiO3 this contains one of the simpler polymeric chain anions. I have tried to remove the picture - with no success- beats me!. I have added words that explain the structure but the picture needs replacing.--Axiosaurus (talk) 18:16, 2 November 2008 (UTC)
thread_title:  The structure picture is incorrect and misleading 

message: Problem with some content of the chembox:
| SystematicName = Disodium oxosilanebis(olate)
In organic chemistry, the suffix "olate" commonly refers to an alcoholate, not to the conjugated base of an inorganic acid. Disodium oxosilanebis(olate) is very misleading for the reader. The conjugated base of the metasilicic acid has to follow the same rules as for these of other inorganic acids whose base is also an oxyanion: e.g.
* sulfuric acid: sulfate and not sulfonate;
* phosphoric acid: phosphate and not phosphonate.
All the rules of organic chemistry nomenclature are not directly transposable to inorganic compounds. The analogy with the carbon atom has its limits, even for silicon a close cousin of carbon. Shinkolobwe (talk) 14:45, 28 December 2010 (UTC)

thread_title: Substitutive names are most often not appropriate for inorganic compounds

message: There appears to be no word in the article about uses for dentistry. Anyone know why? Googling for info results in bad proprietary noise, and worse, often no real info at all (bad edits based on stolen text for domain placeholders and other web trash).
Superficially, to me (as an extreme non-expert), it seems that in reaction to tooth enamel and dentine it might form a nonsoluble calcium silicate that reduces porosity (and therefore sensitivity) and vulnerability to wear, and that the reaction might cease naturally at the surface in a way analogous to that of aluminium oxide on the surface of aluminium, and offer analogously similar advantages.
There is clearly some evidence (written on the sides of many dental products like gels and toothpastes) that something of this nature is intended, yet no mention of this exists in any form in the Wikipedia page for sodium silicate. If someone knows enough to correct this reliably, without some proprietary interest, please add it.  —Preceding unsigned comment added by 86.144.140.233 (talk) 14:56, 25 April 2011 (UTC)

message: In Ceramic production small quantities are added to clay slip.  When the slip is poured out of the plaster mould a layer of clay is left behind on the surface to create the tableware, hollow decorative piece, wash-basin etc. The deflocculant stops the clay from settling out to the bottom of the mould; the particles stay in suspension while the necessary thickness builds on the plaster surface.<<Simon Armstrong, amateur potter in demonstration.  —Preceding unsigned comment added by 212.139.247.229 (talk) 17:59, 16 May 2011 (UTC)
replies: text: I am a potter. Potter unfortunately consistently use flocculant and DE-flocculant the wrong way around. When they do describe what the compound is doing it is the opposite of the word they use. Nzkennys (talk) 08:33, 17 March 2024 (UTC)

message: I came to this article on redirect from "liquid glass" while looking for info on nanopool's product of that name. That product is sprayed onto surfaces leaving a 100 nanometer thick coating, which repels water and has anti-bacterial properties. As far as I can tell, the two materials are unrelated. There was considerable hype a couple of years ago, and this year the product won an award in a hospital setting. Should there be an article on this material?

message: The term "detergent auxiliaries" is used without a definition. As far as I know it is not a standard english term. Seem to be industry jargon of some kind. It needs to be defined for laypeople to be able to understand. In general the detergent section needs a few more sentences. Cshay (talk) 00:10, 15 March 2012 (UTC)

message: The very start of this article says: "The pure compositions are colourless or white, but commercial samples are often greenish or blue owing to the presence of iron-containing impurities."
The first thing that came into my mind when reading this was: greenish/blue-ish..., that rather points to copper-containing impurities (maybe in addition to the presence of iron-containing contaminants).  Is someone able to verify this?  — Preceding unsigned comment added by 83.101.29.130 (talk) 10:50, 27 November 2013 (UTC)

message: The history section is a bit confusing.  It dismisses the earlier reports of potassium silicates in the 1500s and 1600s, and seems to claim that Fuchs was the inventor of "true" waterglass in 1818.  However the references seems to say that his waterglass too was potassium, rather than sodium, silicate. What gives? --Jorge Stolfi (talk) 01:19, 27 May 2018 (UTC)

message: In the section "Sealing of leaking water-containing structures" it states "...secretly buy 140 quarts (160 liters)". A liter is bigger than a quart, so this lacks credibility.
