Seven village metal?

Since last year, in jawa tengah we have a lot of pendok gongso for sale. Most of them is jogja style with silver plate in the middle. The price is quite dear due to gold content (very little) and hard to make, unlike silver easier to work on.

Some people selling Bronze pendok (dirty - and called it gongso). If broze; when cleaned we can see the bronze color but with gongso - you still can see the gold color like Suasa (but the one with very low gold content). As you may know suasa also have different colour depending their gold content.
Just my one cents opinion..

Yes, there's no reason why bronze cannot not have gold in it, I think there could well be as many recipes for bronze as there are uses for it.

By definition, any alloy of copper and tin where copper is the principal metal, and zinc is not the principal secondary metal is a bronze.Once zinc becomes the principal secondary metal you have brass.

Suasa can be accurately translated to English as "rose gold", but gangsa is by definition a bronze, albeit, a bronze that contains a small quantity of gold.

Rasjid, I've had a lot of copper pendok through my hands over the years, and some of those were sold to me as gangsa, but I don't think I've ever had a true gangsa pendok in my hands, at least not that I was aware of.

With suasa I understand that the karat value can go as low as 4K or 5K and still be legitimate suasa, I don't know where the karat value of gangsa would kick in.

I wonder if these gold-like materials are pinchbeck?

Pinchbeck is quite difficult to tell apart from gold, without testing, and it was known in Jawa, because I have Javanese watch chain ornaments and fobs made of it.
