Hi. I am new here. Amazing to have this section to solve the problem. thanks to all.

I need to make an earring with 20ct gold. Should I use 22ct or 18ct to pass the hallmark? I don't see Cookson sellinng 20ct solder. or Can I use piece of 24ct gold?

It will be hall marked as 18ct, so 18ct solder is OK.
1. Make sure the seams are neat, to avoid a possible mismatch in colour.
2. Sorry if you know this already, but the cheapest way to buy gold solder is to buy wire solder by length. Dennis.

Great! thanks a lot. I didn't know I can buy the wire solder to save money. Good tip!
