Yuck. 21st century... Coating working parts with cadmium... Allowing workers to handle it... I do not know it has more benefits than drawbacks.After looking at this product line up, think cadmium is here to stay. Mind blowing.

Cadmium Line Up.
By simply does not buying material containing cadmium analysis is needed anyway for regular refining job, so XRF will immediately tells you what is in thereAnother way to put it is, "how do I avoid cadmium"?
You can download it from the forum.Any one with soft copy of hoke book can send me via whatsap no +255788747144 or email [email protected]
CaO will not go anywhere, it is one of the most refractory oxides used to day, CdO on the other hand may go into the Cupel.When cupelling with lead are there any indications that the sample is contaminated with Cadmium?
While cupelling with a torch (exhaust hood and respirator) a dark red liquid appeared on the lead bead. Since the melting point of CdO is about 950C, which coincides with cupelling temperature, could the red liquid be Cadmium?
Is it correct that the cupel will have absorbed most of the CaO and the cupel may be disposed of as non-hazardous solid waste.
Bonus question: Is there a rule of thumb as to how much Lead is lost to the air while cupelling?
Would the loss to the air be similar for CaO?
I truly appreciate the access to professional knowledgeable insight. Thank you
