As we discussed today, if we want to digest more sulfide, silicate, and oxyhydroxide samples using the sodium peroxide fusion method, I recommend purchasing 000g of sodium peroxide. Purchasing OREAS standards is also important. The OREAS standards I recommend are OREAS 000 and OREAS-000b.

Also, if we can order 0 more crucibles from Katanax, we can speed up the digestion process. I can handle the purchase of the crucibles; I learned how to do it the first time.
