Hot water encourages slaking. I am using plenty of water, that encourages better slaking. If the lumps had been larger I would have broken them down to centimeter-size (half inch). After sieving, it will settle overnight so any excess water can be poured off. Dried lumps slake, damp or wet ones do not, that is why I dried the clay thoroughly in step 1. Most clays will slake within minutes (if the lumps are not too large), I left this one for about 30 minutes.
