探析当代柴烧中的火痕成因

Brief Analysis for Formation Cause of Flame Marks in Contemporary Woodfired Ceramics

柴是人类窑业史上最先利用的一种燃料。在没有电窑、气窑的年代,柴烧是最为普遍的陶瓷烧成方式。柴窑中,木材燃烧产生火焰和木灰,火焰带着木灰在窑里流窜。传统的柴烧会将器物放置在匣钵内,避免器物与火焰、木灰直接接触从而保证器物釉面的完美。而当代柴烧的追求截然相反,作品大多数采取裸烧,烧成时窑内木灰流窜,坯体上会留下落灰及火焰痕迹,支烧处会形成无釉的素点。

Firewood is the first type of fuel which was applied by humans in the history of kiln industry. In the periods when there was no electric kiln or gas kiln, wood firing was the most prevailing ceramic firing mode. Traditional wood firing places the porcelain in sagger box so as to avoid direct contact between the porcelain and the flame and wood ash. In this way, the perfect glaze appears on the surface of porcelain. The contemporary wood firing takes completely the opposite approach. Most of such works are subjected to naked firing. The wood ash flows in the kiln during firing period, leaving wood ashes and flame marks on the green body. Unglazed solid spots are formed on the propping place for firing purpose.
