The upper mantel is the part of the mantel nearest to the Earth's surface. It is a little cooler than the lower mantel therefore more viscous, or pasty, than the lower mantel. Temperatures range between 932 °F-1,652 °F. at the upper boundary with the crust to over 7,200 °F at the boundary with the core. Although the higher temperatures far exceed the melting points of the mantle rocks at the surface (about 1200 °C for representative periditute), the mantle is almost exclusively solid. The enormous lithostatic pressure exerted on the mantle prevents "melting," because the temperature at which melting begins (the solidus) increases with pressure.

How to install a mantel properly?

To install a mantel properly, first locate the studs in the wall where the mantel will be mounted. Use a level to ensure the mantel is straight. Secure the mantel to the studs using screws or brackets. Finish by caulking any gaps between the mantel and the wall for a clean look.
