I swear one day I will write a book entitled the one hundred and one uses of salt. The stuff is incredible! Mixed with an equal amount of vinegar and you can change the colour of copper to a blue or green. It took a bit of adjusting when it came to how long I should leave the copper pieces in the solution and how long I should leave them to air dry but two days later I got my eureka moment. I am very happy with the colour and crossing my fingers it’ll last as there was no way to seal such tiny pieces; believe me I tried!
