材料:用一般作磚瓦用的泥土,搗成10公厘的小块;另外把烟煤燒过剩下的灰,用φ1.5公厘孔眼的篩子过篩。用体积法量泥土8～9分,烟煤灰1～2分,加适量的水,混合均匀,并加反复翻动、捶击,使它达到象作磚坯那样的泥巴。制造:用一块平底板,撒一些烟煤粉。然后把附图的工具扣好,放在平底板上,并填入泥巴摏实。用鉄絲割断器沿着工具的上平面把它割平,又沿着中間的鋸縫割开,一次作成两块。最后把多余的泥巴去掉,用合适的小管子 MATERIALS: Muds made of generally used brick and mortar shall be tamped into small pieces of 10 mm. In addition, the remaining ash of the bituminous coal shall be screened through a sieve of φ1.5 mm. With the volume of soil measure 8 to 9 points, 1 to 2 minutes of bituminous coal ash, add the right amount of water, mix well, and add repeatedly flip, thump, so that it reaches as the brick for the mud. Manufacturing: Sprinkle some bituminous coal with a flat bottom plate. Then fasten the tools in the photo, put them on the flat floor, and fill in the mud.
