And pots may perhaps block radiant heat from The weather, leading to cooler patches. To minimise this, two factors assistance: high thermal conductivity, so heat speedily evens out through the shelf; in addition to a low thermal expansion coefficient, Hence the forces created by differential growth are minimised. Also, a more elastic material would support minimise the Establish up of stresses, as being the shelf can flex to soak up the stresses, even though this doesn't really implement A great deal into the conventional flat shelves we use.
