It is massive, but not tested yet.

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

Best regards,
Willem

Thank you Willem.

When I grow up, I'll get one of these in gold. I guess that the gold content must be that low in order to do the heat for the enamel work, and be sturdy enough for use.

Willem,

Congratulations on an outstanding purchase. Beautiful rencong. Definitely a keeper.

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.
