Dan Kwian pottery is a beautiful and unique pottery which brings both reputation and large amount of income to Nakhon Ratchasima province. However, most of the factories in Dan Kwian district are still using basic production techniques which have been inherited for many decades especially drying technique. At present most factories in Dan Kwian are drying their greenwares in grass-walled huts.This causes not only longer drying time but also the drying period to depend upon the seasons. Critical moisture content of Dan Kwian pottery was studied in this work in order to be used as the data to improve the drying technique of Dan Kwian pottery. It was found that the critical moisture content of Dan Kwian pottery is about 10 - 15%. Therefore we should be able to decrease the drying time of Dan Kwian pottery by increase its drying rate after its moisture content was reduced to below 10%.
