Review on EuroTool Magnesia Soldering Block 1 5 by Lynn Cole

This soldering block makes an excellent refractory for heating both sides of a piece of metal with a torch. It is also an excellent resting place for hot materials such as a freshly fired plunger or for setting down the crucible when melting silver and gold. I've had it for over 6 months now and haven't noticed any major signs of wear. It will most likely last a long time for me. If you're the type that likes to push rocks in to create a hole to put a ring or piece of metal in, this works great. It's a soft brick material, not silica, so you won't die from inhaling silica dust!
