Pancake Syrup Instead Of Sodium Silicate For Crackling

Sodium silicate does not cause the cracking surface because of any "glue" or "sticky" qualities.  It does so because of the action on the water chemistry that makes the clay plastic.  It kills the plasticity of the outer layer of clay but leaves the underlying layer still plastic and stretchable.

 

You might get SOME effect...... not sure what..... but it won't duplicate what sodium silicate actually does. 

 

As they say.... try it and tell us what you get.

Spooze;

1/3 Karo syrup

1/3 your clay body as powder

1/3 vinigar

 

Any cheap syrup will work

This is for repairing cracks in greenware. The syrup keeps the area moist while the vinigar does its job. do not keep. It stinks after a day.

TJR.

Jbaymore, actually, I was referring to the crackling you write about. I don't have any silicate yet but read pancake syrup have the same effect. Thanks for info. I might try it to see what it does compared to the real thing.

 

Pres, thanks for correcting. Ciuldnt find how to do it. :)

 

Tjr, good tip to know on repairs.

 

Keeping studio notes on all your tips for future. Ty

If you use pancake syrup AND use a heat gun you'll get something for sure.... but it has more to do with the heat gun than the pancake syrup.  With sodium silicate...... you do not need the heat gun.  Some people use it and assume that the heat gun is necessary.... it isn't. 

 

The issue for the silicate is the timing.... the longer before you start to stretch... the deeper the cracking.  I am using timining for my work that is in the range of no more than a couple of minutes.  A lot depends on the particular clay body also... and its particle size distribution as to the timing.

Hi john,

My understanding was the heat gun was needed just for drying the SS and then the dried SS produces the cracks. So will the SS produce the cracks just by way of deflocculating the clay you apply it too and drying and stretching just produces a different effect,  or am I way over my head here? :-)  either way thanks for the info.

Tom,

 

If you add peroxide, it keeps the stink down.  I've had some keep over the summer, in a sealed container, with only a bit of mold grow on it.  Even with the mold, it still smelled the same.  For some reason, to me, it smells like the inside of an old tent...

No "drying" of the sodium silicate is necessary.... just time.

 

If you ALSO dry the silicate....... you get a "double" effect.  The impact of the silicate chemical action in the water.  AND the drying of the surface... that you get with ONLY a heat gun.  And maybe a tad more than that since the coating of sil dries on the surface... much like the pancake stuff might.

 

I've been using this trick for something like 30 years or more. (not the pancake approach ;) )

PS:  Do NOT reclaim failures into your reclaim... the clay with the sil is going to screw up the water chemistry of ALL of the reclaim.

Ben;

I know that this was mentioned in another post by both of us.I will try it next time I repair something.

Ha Old Lady!

 

It's whatever they used to use to waterproof the canvas material.

 

I remember that smell from every camping summer! I think it was also on the rubberized air mattresses, too. Boy, they got heavy after a few days on the trail, but worth their weight at night!
