allrocketspsl Posted November 26, 2011 Posted November 26, 2011 (edited) anyone want to trade a "CTFC" for a gallon of Sodium Silicate Edited November 26, 2011 by allrocketspsl
TheArchitect23 Posted November 26, 2011 Posted November 26, 2011 (edited) Much Cheaper Here <--- Edited November 26, 2011 by TheArchitect23
dagabu Posted November 26, 2011 Posted November 26, 2011 Also; Seattle Pottery had 5 gallons for $47.50 and a gallon for $13.50. -dag
Algenco Posted November 26, 2011 Posted November 26, 2011 got you all beat US Pigment $8 gal http://www.uspigment.com/chemicals.shtml
allrocketspsl Posted November 26, 2011 Author Posted November 26, 2011 got you all beat US Pigment $8 gal http://www.uspigment...chemicals.shtml yep just ordered thanks mate!
Col Posted December 2, 2011 Posted December 2, 2011 Sodium silicate powder costs a little over £7 a kilo here ($11), how much active chemical is in a gallon of solution?
Algenco Posted December 2, 2011 Posted December 2, 2011 it's supposedly very difficult to convert the powder into liquid solution
Mumbles Posted December 2, 2011 Posted December 2, 2011 I believe a typical concentrated solution is around 40%. As Algenco said, it's supposed to be rather difficult to achieve this concentration from powder. However, that syrupy liquid may not be necessary. I bet a thinner solution would penetrate better, and be easier to prepare.
Algenco Posted December 2, 2011 Posted December 2, 2011 If I hadn't already purchased one I could have made out like a fat rat on that deal
TheArchitect23 Posted December 2, 2011 Posted December 2, 2011 Credit To The Google Search But, crush 6 G of silica beads from desiccant packs,add to 8 G sodium hydroxide ( heated )add 10 ml water stir until fully dissolved.

I was told that you could not make it from silica beads and sodium hydroxide... Have you tried it yourself? -dag
TheArchitect23 Posted December 3, 2011 Posted December 3, 2011 Im waiting on ups for my sodium hydroxide, and sodium silicate. That's what I plan on trying out as a recipe. The bought version will be my comparison.

Col Posted December 3, 2011 Posted December 3, 2011 Dag, nurdrage has a vid on youtube for making sodium silicate from crushed silica gel crystals and caustic soda. I have some colour changing silica beads and caustic soda ..i may give it a whirl tomorrow.
TheArchitect23 Posted December 3, 2011 Posted December 3, 2011 I would digest not using color change silica beads. The color changing ingredient is poisonous. Plus may alter the reaction.
Col Posted December 4, 2011 Posted December 4, 2011 (edited) The blue to pink is toxic as it contains cobalt chloride, i have the safe orange to green type which apparently contains iron salts as the additive. Edited December 4, 2011 by Col
Mumbles Posted December 4, 2011 Posted December 4, 2011 Depending on what MSDS you believe*, Cobalt (II) Chloride is about half as toxic as copper oxide or barium nitrate. Are you going to stop using them too? * - There are conflicting values of 80mg/kg or 766mg/kg for oral rat toxcity.
Col Posted December 4, 2011 Posted December 4, 2011 I guess whatever is used for the color change it must be a small percentage of the whole. From what i can find, iron doesnt react with NaOH so logically its presence shouldn`t make much, if any difference to the end result. For the cost of a few grams of silica gel and caustic soda, i`ll give it a go and see what happens
allrocketspsl Posted December 5, 2011 Author Posted December 5, 2011 got you all beat US Pigment $8 gal http://www.uspigment...chemicals.shtml so mine is in gel form now what add water to it or use as is?
dagabu Posted December 5, 2011 Posted December 5, 2011 so mine is in gel form now what add water to it or use as is? You need to find out what the concentration is, most are 40% and are used as is. If you have a gel, it may have something else in it that may cause it to not work for you. Try a small amount in a cup, add 10% water and see what that does. -dag
