Sodium Silicate || Water Glass: (Uses from Industrial to Daily Life)

Sodium Silicate Uses: In this video, we show the amazing Uses of Sodium Silicate / Water Glass in industrial to our daily life. It is also known as liquid glass and is used as a concrete sealer, a deflocculant in ceramics, a coagulant, cardboard adhesive, soil stabilizer, chimney sealer and in many other industries.

I have a Hobbies and Crafts magazine from the 1940s and it shows how to make "trick" matches by dipping the stalks of a match into waterglass up to the head, then letting dry and putting them back into the box. The waterglass is invisible. You then give them to a friend and watch their frustration as they light them, the head flares up and they go out instantly after that!

[@ClownWhisper]

Some of the facts are inaccurate. They show an image of a crackle glaze effect and attributed to sodium silicate which is not the case. Hopefully no new Potter's will attempt to get a crackle glaze effect by using sodium silicate. Sodium silicate will cause a crackled clay body not glaze it would actually prevent a glaze from crackling because of the addition of silica. If you are developing a glaze and it's not intended to be a crackle glaze yet you find it crackling the first thing you do is recalculate more silica into the formula.

[@EnvironMolds]

Sodium silicate and potassium silicate are both silicate compounds, but they differ in their chemical composition, properties, and applications. Here's a comparison of the two: 1. Chemical Composition Sodium Silicate (Na2SiO3): Composed of sodium oxide (Na2O) and silica (SiO2). Potassium Silicate (K2SiO3): Composed of potassium oxide (K2O) and silica (SiO2). 2. Solubility Sodium Silicate: Highly soluble in water, forming a viscous, alkaline solution. Potassium Silicate: Also soluble in water, but typically less viscous and slightly less alkaline than sodium silicate solutions. 3. pH and Alkalinity Sodium Silicate: Tends to have a higher pH (more alkaline) in solution compared to potassium silicate. Potassium Silicate: Slightly lower pH, making it less alkaline and potentially less caustic. 4. Applications Sodium Silicate: Adhesives and Binders: Used in making cardboard, paper, and refractory materials. Construction: Used in concrete treatment, as a soil stabilizer, and in fireproofing. Water Treatment: Acts as a corrosion inhibitor and is used in water softening. Detergents: Used in cleaning products for its ability to break down oils and fats. Potassium Silicate: Agriculture: Used as a fertilizer and plant protectant. It strengthens plant cell walls, making plants more resistant to diseases and pests. Coatings: Used in high-temperature coatings and paints, especially for metal protection. Fireproofing: Similar to sodium silicate, it's used in fireproofing applications. Construction: Used in mortars, cements, and concrete to improve durability. 5. Reactivity Sodium Silicate: More reactive with acids, leading to faster setting times in certain applications, such as in grouting and sealing. Potassium Silicate: Less reactive than sodium silicate, which can be advantageous in situations where a slower reaction time is needed. 6. Environmental Impact Sodium Silicate: Generally considered safe for the environment, but its higher alkalinity can be more corrosive to both skin and materials. Potassium Silicate: Also environmentally safe, but its lower alkalinity makes it slightly safer to handle and less corrosive. 7. Cost Sodium Silicate: Typically cheaper and more widely available. Potassium Silicate: Usually more expensive due to its specialized applications, particularly in agriculture and high-performance coatings. Summary Sodium Silicate is more commonly used in industrial applications where cost-effectiveness and strong alkaline properties are needed. Potassium Silicate is preferred in agriculture and specific industrial applications where lower alkalinity and less corrosiveness are advantageous. The choice between the two often depends on the specific requirements of the application, such as reactivity, pH, and environmental considerations.

I'm a Potter. This video is correct that it's used for crackle effect but what they're showing is not crackle effect LOL they're showing cracking in glazes which is nothing to do with sodium silicate. It's bizarre that the person that made this video would not have researched it correctly and got the correct pictures

[@ClownWhisper]

@J d are you just a bad troll or an asshole? Or both? Again they show a glaze effect of crackle and attributed to water glass which has nothing to do with the picture they show. That particular crackle effect is caused by the makeup of the glaze and I can assure you it is not water glass that's added. Typically you get that effect with abundance of nepheline syenite and they lack of silica. Sodium silicate would actually prevent the crackle effect that they show in the image provided. Sodium silicate is used on the clay body itself to crack the clay body not the glaze as shown in the picture. So someone that is new to Pottery is going to try and get that glaze effect which is desirable an attempt to use sodium silicate on the clay body as Illustrated and the two things are totally different techniques. To call this a great video when there's a glaring are like that it's pretty fucking stupid. Also it's more accurate for them to have said carbon dioxide causes sodium silicate AKA water glass to harden but they do not add that information they say heat causes it which is inaccurate. I don't understand why smart-ass people have to be contrary to every comment that is not placating a video creator. Are you the creator of this video or a friend?

[@jussayinmipeece1069]

@@jon_byler so essentially it acts as a plasticizer. So in that case all that's needed is managing the ratio properly to get just the right amount of slump wouldn't you say? I use pepsi or coke or molasses where i can get it.

[@jon_byler]

@@jussayinmipeece1069 plasticizer is the wrong way of thinking about it. it is a -deflocculant. it means less water is needed to provide a fluid mix. This can really screw you up if you mix your concrete by sight/feel, rather than weighing ingredients. It has uses when trying to cast concrete/mortar and get it to fill more easily all of the voids in a mold. might be helpful for grouting (filling the holes in) concrete masonry units. A more experienced and knowledgeable mason or concrete engineer could tell you better if it's a good idea for a particular application. There are other defloccuants out there that are less alkaline, based on other chemistry, etc.

[@jussayinmipeece1069]

@@jon_byler actually its just different ways of saying the same thing. An additive that reduces the friction between the solid components, breaks the surface tension of the liquids allowing the mixture to flow and mix better with less water. The technical name i have always seen is plasticizer. Generally unless you are casting critical components such as bridges and columns for high-rises then the amount does not have to be critically mixed. Eyeballing and experience is usually enough to a certain extent. Say for example i am doing a mix for a suspended slab for a roof 6 inches thick. For every batch with 5 bags of cement i pour one one liter of regular coke or a pint of molasse with one 2 pounds of fibre. In this case i am looking for THREE things flow into small crevices, (so less voids and air) compactness and longer initial curing time. So the net result is that the additive will have no deleterious effect on the actual concrete once its cured but it will slow water evaporation allowing for the chemical formulation of concrete BEFORE it runs out of water leading to cracks.
