Abstract

To reduce energy consumption in ceramic process, Investigation of fast firingmethode to produce relief product has been carried out. Best Ceramiccomposition applied to produce rellief without defect when burned in normal firingtraject. The composition consists of Kalimantan clay :52,5 %, Penujak clay 10%,Felspar RRC 16%, Talk 2,00 ? 5,00%, limestone 2,5% - 6,50% and Ballclay13,00 ? 13,50% and agree with stoneware qualification. In this research, Desiredtemperature reached at 7 hour, decreased 2 hour compare to normal firingtraject. Crack occured on some rellief products indicated that the product withdiffer thickenness significantly along ceramic body can not be applied into fastfiring process.Kata kunci: keramik ukir, stoneware

Abstract

A downdraft kiln using LPG as energy source with capacity 1 m3 and maximumfiring temperature 13000C has been constructed and midified to give better heatdistribution. For firing ceramic process, most of Balinese and Lombok craftsmenuse firewood as energy source. This method is inefficient from the production rate.Point of view, downdraft kiln can help the craftsmen to process ceramic easier,faster and cheaper. Downdraft kiln using LPG has been selected as an alternativekiln due to minimum pollutant produced compare with updraft kiln using coal orfirewood. The kiln constructed has fulfilled the requirement of kiln firing processquality in which the firing causes sintering process in the ceramics body. The kilnwith a capacity of 1m3 can reach a maximum firing temperature which of 13000C.To test this modified kiln, some carved ceramic has burned into the kiln. Carvedceramic has been chosen caused by need more good heat distribution than otherceramic design product and have differ thickennes in all bodies.The final productgive a better product whithout defect compare to product burned into unmodifiedkilnKata kunci: tungku hemat energi, keramik ukir, stoneware
