Hello Willem,

Quote:

I had the gold tested today with x-ray technique.
56 % gold = approx 13 K.

Thanks for the additional info!

BTW, what are the amounts of the other metals utilized with this alloy?

Regards,
Kai

Pfew, I did not write them down.

There was a lot of silver, some copper and zinc, and to my surprise also a bit of lead approx 1%
Maybe the lead content was caused by the enamel

I am not surprised at all about the silver and copper, slightly surprised about the zinc.

You might be right about the lead in the glass enamel..........

Pfew, that was quit a few years ago that I had this rentjong tested.

Today I had it tested again, I brought only the small round cap from the back allowing to test the outside with the enamel, and the inside without enamel.

Here are the results.
