Dan Kwian Clays for Slip Casting

Sirirat Rattanachan*

 
ABSTRACT: In the present study, Dan Kwian clays was characterized and prepared for slip casting. The very high plastic (HP) and mild plastic (MP) Dan Kwian clay was mixed with Ranong kaolin and quartz for preparation of slip casting in various compositions. The relationship between viscosity and the amount of sodium silicate used was determined for these slips in the presence of various compositions. The cast thickness and casting time of slip samples were determined. The results showed that the suitable composition of Dan Kwian slips consisted of HP clay content less than 60% wt of total slip weight. The casting of Dan Kwian slips was achieved within 1 hour. Thus, it is possible to prepare Dan Kwian clay body for slip casting.
