72. Using Sodium Silicate to Create Crackled Texture with Hsin-Chuen Lin 林新春 岩花瓷拉坯示範 

My recipe is the same as an oxide wash, but instead of water use sodium silicate. So it looks something like: 50% oxide 50% frit hydrate with sodium silicate

Please watch my glazing videos on glazing the sodium silicate texture vases. Just search keywords “ Hsin glazing sodium silicate”

You should wipe off the sodium silicate when it is still wet.

@@hsinchuen Thank you!

Hi there, in my experience, the torch produces grain in the sodium silicate and the heat gun does not

maybe write him at his etsy store

Yes, sometimes I apply chattering texture the the area you mentioned.

@@hsinchuen thinking alike :)

yes you do to make the slip with the sodium silicate stick better

Dvod22 No, just using slip will just stretch out with the clay making a thinner layer of slip. The sodium silicate dries to form a crust. As you stretch the clay, the cracks form and the exposed clay stretches and the layer with sodium silicate does not. How heavy you coat the silicate will effect the size of surface between cracks. If you get it too dry with heat gun or stretch too thin, it will tear holes in the wall. It takes a little practice but makes a wonderful surface. Without colored slip, it makes a nice texture for the new potter's choice celedon glazes to accent. I have used similar color of nontransparent glaze on the smooth areas and the results are very nice.

Ronald Barton what if you paint the colored slip on, and use a torch to dry it before it chips off and then belly the pot?

If you over dry the clay, it tears holes in the deeper cracks as you stretch it out to shape. The silicate dries and makes the crackable crust with the surface layer without drawing as much water out of the deeper clay so it stretches out smoothly.. Without it I am fairly sure you'd find that it would not be able to be dry enough without drying pot too much to stretch to more than a tapered vase rather than a sphere shape which shows the cracks the best.

Thanks, very helpful

@@ronaldbarton8180, how to create large, deep cracks?
