I needed a stable surface for silver soldering. I've used a carbon block for soldering in the past and since the AI had lots of things to solder, the carbon block didn't last very long. Ceramic plates are known to absorb a lot of heat and don't break down as easily as charcoal. I'm happy to report that this soldering board is top notch!
I can't rate the item because I only received an empty (unpadded) envelope that was thrown, or rather floated, on the porch. If the product had actually been in an envelope that said it was "lighter than their smallest box," it would certainly have been broken. Where has the ceramic block gone? Why does a ceramic block need an unlined shell? It may have been someone's first (or last) day at work.
Pros
Material: cordierite ceramic. Acid-resistant, asbestos-free, fire-resistant and non-combustible.
I needed a soldering pad to repair the earrings with silver solder using a butane torch. This did a good job of keeping the overall heat under repair without damaging the base. Brick or metal surface. The holes also help to hold the small wires that are attached I used on this repair.This is a great finish for small to medium sized jewelry and fits easily in my tool box.
