Anodized Aluminum is the best way to add colour to Chainmail designs. It's inexpensive, and the colour is added to the rings when they are coil form, but a process that involves dye, electricity and major know how. We do not make our Anodized Aluminum, as it's too dangerous to set up a process like this in our studio. We import these rings so we do not have control over quality as we would if we made them. Therefore we recommend that you order more rings than you think you need because there is a huge colour difference between batches... We even see a difference in colour between sizes, which isn't ideal, but we can't control. It's still the best, more inexpensive, easy to manipulate way to add colour to your designs!
