Laura and volunteers from Long Buckby Green Spaces teamed up and we dig our clay from Cotton End Park in Long Buckby, Northamptonshire. The clay is rich in iron and it fires to a beautiful red colour. We tested the clay to 1260°C and it fired to a beautiful dark red cherry colour. Clay blisters' started to appear at this high temperature but it did not melt. Test are ongoing.
After is being dug the clay is left in buckets with water for a few days. We use rain water most times.
Then with a drill we mix it until is well homogenised and of consistency of double cream. Is now ready to go through a mesh so all unwanted materials such as stones, wood are being taken out. We have 2 vegetable trugs with a couple of old linens stapled to them; we sieve the liquid clay in here and leave the clay to dry until reaches a dough like consistency. This can take a few days or weeks, depending on the weather.
We also leave the clay on plaster bats to dry to speed up the process.
