Cleaning the Quartz Crucibles

1. Wash the crucibles with DI water and a small piece of a scouring pad (no soap).
2. Rinse several times with DI water.
3. Place crucibles in a 10% HNO₃ bath for 12 hr.
4. Rinse 3 times with DI water after the acid bath.
5. Dry the crucibles in the oven at a maximum temperature of 60°C.

Some crucibles will develop a thin white cloudy film, become spotted, or start flaking. If any of these things happen throw the crucible away in the sharps container. When the crucible undergoes one of those changes the quartz has started to react at high temperatures, and could start contaminating the sample.
