Modern log burners generate far more direct heat than an open coal fire. This intense temperature can damage the old enamel finish.
You need a decent gap between the stove and the stone. Building regulations dictate specific clearances to combustible and non-combustible surrounds.
That catching usually means the baked enamel layer has started to lift away from the base stone. Damp conditions often cause the layers to separate.
Stop using a cloth. A soft brush removes loose dust without snagging the fragile edges. Fixing loose paint requires specialist glue.
Hidden iron dowels slot directly into the stone.
Plaster sets the joints firm.
Decades of soot strip the original sheen away. The underlying slate turns a chalky grey when the surface enamel wears thin.
Many restorers apply a simple black grate polish. This feeds the porous surface and brings back a uniform colour.
