Why do you burnish clay?

Burnishing is an ancient tradition and evolved before glazes had been developed (source). It was used as a way of decorating ware, but also making pottery a little more water-resistant. Whilst burnishing does create a moisture repellent surface, especially if waxed, it is not watertight.

What does vinegar do to clay?

Vinegar is also used in clay bodies to increase acidity to improve plasticity. The acid works to neutralize sodium ions (from water, leaching feldspars) that tend to deflocculate the clay. Excessive acid may tend to dissolve more feldspar or nepheline syenite negating the effect.

Does air dry clay crack easily?

Your air dry clay sculpture is most likely going to crack. Accept it. Cracking is normal in air dry clays: it's caused by shrinkage because of the loss of the water inside the clay body.

Why is my air dry clay crumbling?
