Wild clay dries soooo slow


Recommended Posts

I’ve been doing some experimenting with natural clays I’ve hunted down in my area. I’ve found one that fires well, but dries slower than any clay I have ever worked with. Anyone know what the chemistry of that might be? Or what might be a fix?

Organics: most likely Ord or Muck variety humus. Both carry very high CEC values (plasticity), as both absorb and hold moisture. Not uncommon for these materials to take several days longer to dry compared to commercial clay. You cab burn off Organics by heating up to 1150F. Organics may be the only plastic material in your wild clay: burning them off might have adverse effects. Testing is the only way to know. There is a Facebook group- "Wild Clay Club" devoted exclusively to processing/firing locally sourced clays. Not many threads about it on this site.
