Drierite can be reused after drying. The specific drying method is as follows:
1) Pour the drierite into a heat-resistant container and spread it out as far as possible.
2) Put the drierite in the oven and dry it at 200 °C for one hour. Observe whether the drierite
turns blue. If not, increase the drying time until it turns blue.
3) After drying, transfer the drierite to the glass container before the drierite temperature
drops.
4) Cool the drierite and then put it back in the canister.
