陶土粉與鋸木屑之比例1:5 (v/v),混合均勻後,先將少許放入造粒機,令其轉動並噴水使成小顆粒,然後再慢慢撒入土粉與木屑之混合物並同時噴水,漸形成大小約10~18 mm圓形顆粒。待陰乾後於電氣窯內燒之,開始燒時,窯門微開,讓水氣灰煙逸出,溫度升至500℃左右時才關緊窯門,待溫度升至1000℃,固定溫度維持七小時,即可完成。自製之發泡煉石,外觀美好,吸水性佳,適合用於盆栽。磚窯廠因溫度未達1000℃燒出之發泡煉石硬度不夠,易碎。一般土壤粘性不佳,亦不適合供製發泡煉石之用。
Studies were attempted to obtain expanded clay from local materials. Results of the preliminary experiments are summarized as follow. Clay powder and saw dust are well mixed (1:5 v/v) first. A small amount of the material then was put into a grain-formation-machine. Small clay grains were obtained during the rotation of the machine and mist-spraying of water inside. At this time, the mixed material as previously described was gradually added in a small amount into the machine to increase the size of the grain until the size reached 10~18 mm. The prepared grains were dried at room temperature and then baked in the oven. In the beginning of baking, the door of the oven must be open to allow the release of excess moisture and smoke wastes. When the temperature reached 500℃, the door was closed. Expanded clay was obtained after 7-hrs. of baking at 1000℃. The exterior and absorbability of expanded clay were good for culture. The hardness of expanded clay were not hard enough when baked in a brick kiln because the temperature of the kiln was lower then 1000℃. Due to lack of enough adhesion in the field soils, they are not suitable for the preparation of expended clay.
