Non-asbestos fireproof material is fibrous so it is soft enough that one can pin objects on the surface for perfect soldering. Good for filigree work as its surface stays smooth. Magnesia blocks can withstand heat up to 2000°F (1093°C) so non ferrous metals like copper, silver and gold can be melted on its surface.
