I am having trouble preparing a Cu sample , from the heating iron filings with Copper Oxide.

I heat for a l o n g time, in Pyrex boiling tube, until it was read glowing hot.

But no go
is there an optimum ratio of the Cu O to Fe?

we add carbon and copper oxide

Hi Jazz

so youre saying you just add a bit of carbon in along with the iron filings and the Copper oxide?

No, we using only copper oxide and carbon. I am insluding our risk assessment, see if this is the same prac. if yes you will never clean testubes, you can re use tham for the same prac or chuck it.
sorry could not send compleate file, too big.

Thanks for this Jazz
