Slate hearth edging
Basically you’ve got three choices of hearth edging, a chamfer, (which we call “arris”), a pencil ( a sort of subtle rounding) and bullnose, either half or full.
Sawn or chiselled edges
What you don’t want is to leave the edges sawn, unless you’re completely enclosing the slate with a frame or similar. Sawn slate edges are sharp and look a bit rough.
Equally another edge we don’t offer is chiselled, or “dressed”, like a roofing slate. We tried it once. No, just, no. So sharp it was lethal. Like your toes attached to your feet? Good, us too. When it comes to hearths, let’s both avoid the chiselled edge finish.
