    No, copper is extremely soft once annealed. If you can't harden it by forging, or twisting, you can try just using a thicker gauge and as you say an extra easy solder. Dennis

    I regularly solder copper with silver solder and as enigma has said its good practice to ensure you have a tight join. I've tried copper solder, but have gone back to using silver.

    Hi Dennis, tried just using easy solder on some stud earrings this morning, definitly seems to have worked. Lot less squishy. Thanks

    If you are continuing to work with copper Sheena, you might also get silver extra easy solder. It will turn your life around and it is quite inexpensive. Dennis

    I always thought you were supposed to avoid extra easy silver solder? All the books tell you not to use it

    Extra easy solder is actually accepted for hall making. Its uses can vary from repairing an item of uncertain composition, adding something to an item that is already very large and would otherwise be endangered by excessive heating, and use on base metals.

    Its downside is that it is a little grey on silver pieces and is said to be not as strong as the harder grades. That said, I have never had it break, and have used it to solder a detached stainless steel rung on an oven shelf, three or four years ago, which is still intact. Dennis.

    It's better suited to sealing tins of chopped meat and it has no application in jewellery soldering.

    Wonder how much of it was the last tin in the cupboard during lockdown, still as unpalatable I imagine!
