Clay particles have the ability to physically and chemically “hold” water molecules to the particle more tightly than sands or silts. Sands “give up” the water between the pores much easier than silts or clays. A good portion of the water – upwards of 50% – in any soil remains unusable to the plant.
Which soil is best for pottery?
In the terminology of mineralogy, kaolin is a 1:1-type clay that is not very plastic—or easily shaped—and not very sticky, so it will tear if too much stress is put on it. It is the purest material used in pottery and when fired may not need a glaze because it comes out so shiny.
Why is sand not used for making pots?
