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.

How do you add plasticity to clay?

Clay artists tend to think of aging clay as a process of improving the clay's plasticity by storing it for a long time.

Does acid break down clay?

How do you make wild clay more plastic?

For example, by mixing 50% of a clay with 20% shrinkage with 50% of a clay with 4% shrinkage, you will obtain a much more stable material. You can also mix more 'greasy' clays with drier ones, to make them more plastic. To make your clay more stable you can also add fine chamottes.

How do you make clay stronger?

Mix in some PVA glue

You can incorporate some PVA glue directly into the small chunk of clay and knead it. Or mix the glue with water and use this mixture instead of clear water while sculpting. This trick makes the clay very firm and durable. It'll be harder to sand, but it works great for most areas.
