[edit] =======Chembox===========
Can the melting point be higher than the boiling point? -I'm suspecting the author has written the melting point as boiling point and vise versa. Therefore I'm going to do an experiment in a couple of days to see if it melts at 102oC -Got a hold of silica gel, it did not melt at over 102oC

Is silica gel pure silica? --207.81.94.148 03:08, 31 October 2007 (UTC)
[edit] Vandalism ?
Is the following sentence nonsense or am I missing something? Rsduhamel 08:31, 19 Dec 2004 (UTC)
- 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.
Found the original source of the sentence and fixed the article Rsduhamel 19:16, 19 Dec 2004 (UTC)
==Update==--PaladinZ06 22:05, 24 March 2006 (UTC) I've added some information, and changed the content of the timber treatment section. The use of sodium silicate as a wood preservative may not be common, but it was hardly dreamed up in 2005. I am in the process of using an old method at home that uses sodium silicate solution as a wood sealer/fireproofing which is then sprayed with a boric acid solution which keeps the bugs at bay and forces the sodium silicate to gel.
There are several common trade products available containing primarily sodium silicate for treating concrete and other masonry products.
I apologize for any errors I've introduced. I am a total newcomer to this. --PaladinZ06 22:05, 24 March 2006 (UTC)
[edit] Dishwashing Detergent
I've noticed that my dishwasher detergent containts sodium silicate. This should probably be worked into the article.

Sodium metasilicate is also used as a replacement for trisodium phosphate in painting preparation/degreasing. It works well in dishwashing except for the attack of glass. Softer, soda-lime glass is attacked via common ion solution effect, leaving the glass cloudy. As such, automatic dishwashing detergents containing appreciable amounts of sodium metasilicate should only be used for non-glass items like metal and plastics. Glazed stoneware is also susceptible to attack.
[edit] Silica Xerogel
According to the Nasa Space Sciences Questions and Answers FAQ (http://science.nasa.gov/faq/#anchor136932), sodium silicate gel, when air dried, forms silica xerogel, which is a similar to aerogel. Perhaps this wiki should be updated in regard to this?
[edit] Antifreeze (Bad!)
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. Got2code 19:05, 14 June 2007 (UTC)
