Is this the same sodium silicate & same type that can be used to created the crackling texture on the surface of ceramics?

Is 140Tw too thick to brush on to a just thrown pot intended to be stretched (once the sodium silicate has been dried)for a crackle finish. If so, can it be thinned with water before application to suit one's judgement of the surface moisture content or should 100TW be used?

Yes this may be used, you can thin with water if desired.

Can I use this Sodium silicate to create some kind of a crater glaze.?? What else should I add to it, or can I brush on an existing glaze. Thank you

I think you may be confusing this product with another. Silicon carbide is most commonly used to create crater or volcanic glazes. Here is a link for you:

Can a deflocculant be used to stop glaze powder from settling on the bottom of my dipping bucket please?

Hi there, we would recommend using Epsom salts - 1g per 1Kg of glaze.

Hi,
What is the difference between the three 'grades' of sodium silicate; 140, 100, 75?
I have only ever used just plain sodium silicate with no other information on the label. I use it as an ingredient in Lana Wilson's Magic Water, which is the world's best slip (water, sodium silicate and soda ash).
Thanks and best regards,
Carol

The difference between the three grades are the concentration of sodium silicate. 75TW is like thin water, 100TW is like water and 140TW is similar consistency to treacle.

What is the difference between Dispex and Sodium Silicate?
Is it best to use Calcium Chloride to prevent a glaze from settling if so how much do I need to add?
|
Scarva Replies:

Dispex is a mixture of sodium silicate and soda ash. Both Sodium silicate and dispex may be used to defloculate a casting slip depending on your recipe one or both may be used.
Calcium chloride is a powerful suspension agent and should be used sparingly we recommend 1gram per 1000grams of powdered glaze.
