Quartz is an excellent insulator, and using it to support our heating elements or space parts... well we wish we thought of it years ago.


Made of high purity optical quartz with optical grade polish (unpolished edges for texture), these help keep heat away from your joint and in your dish where it belongs.


Using these as a buffer between heaters and sapphire can additionally help mitigate the risk of thermal shock.
