The objectives of the study of Electric Kiln for Craft Works are to design and develop the high quality
electric kiln to respond the present government s policy of OTOP project. The electric kiln should be beneficial to the
productions of higher quality and more beautiful craft works.
In this study, the researcher team had designed the prototype of small size of electric kiln using electricity to
produce the proper heat on heating coils. The proper aspects of the kiln were calculated to meet the needs; they were its
internal capacity, an amount of light bricks, the length of heating coil, heat insulator component, external steel structure,
and the cost evaluation.
The researcher team had designed the electric kiln by placing a number of light bricks on concrete base to
form the designed internal and external outlines of the kiln. The testing process was begun gradually on the kiln
components: baking at 800 degree Celsius along the first 8 hours, and later slowly increasing to be 1280 degree Celsius
within 9.5 hours. The test result shown that the baking temperature of the kiln was higher than the defined one.
On this study, the researcher team had added more coils on the ready – built kiln to get higher baking
temperature; this additional action resulted from the advice of the experts. The designed kiln then had more efficiency
and stability because of its design, controlling equipments, and its automatic baking timer at the end of the baking
process: electricity circuit could be open automatically. According to its designs, the running process could be
convenient, secure, of no pollution, of no wood consuming, and also beneficial for monetary advantage of the country,
