骨粉

Bone china porcelain is basically made by adding bone ash (burned animal bones) to kaolin and petuntse.

基本是加入粉（动物头燃烧后粉末）高岭土和白墩子。

So I bought a bag of superphosphate bone meal from a flowerer shop in town at Town God’s Temple Street and mixed it into each pot as a substitute for new earth.

从城隍庙花店里买了一包磷酸粉，搀和在每一盆泥里，这算代替了新泥。
