Experiment time from day 1 of Chalke History Festival Chalke History Festival
As part of the iron age village with Pario Gallico Thomas Timbrell and Daniel Postma I'm doing a Pictish pottery display.
It's incredibly common to read in archaeological reports of prehistoric pottery being tempered (things added in to the clay mixture to strengthen it and prevent cracking in the pottery) with powdered quartz.
But have you tried to break quartz into powder by hand before? It's super hard stuff.... Rock hard in fact! πͺ¨
So something I've heard about long ago and been meaning to try was hearing the quartz in a fire, quenching it in cold water and THEN crushing it. I was amazed at how well it works! The stuff just crumbles to powder practically on its own. So new pottery temper material officially unlocked π
