About the stone
Getting to know Jämtland Limestone Black
Something rare: a naturally black limestone, found in Sweden only in Jämtland. Honed it turns almost coal black; planed, blasted or flamed it lightens to a soft charcoal grey.
Where to use it
Jämtland Limestone Black is mainly specified for interior flooring, stair treads, facades, window sills, worktops and tables and interiors. Limestone and marble are more sensitive to acids than granite; an impregnating sealer and pH-neutral cleaning keep the surface at its best.
Finishes
- antiqued: brushed and aged, with softened edges
- sandblasted: finely roughened and evenly matt
- brushed: softly textured and pleasant underfoot
- honed: smooth and matt, shows the pattern, for interior floors
- flamed: rough and slip resistant, for external paving and steps
- planed: matt with a light texture
- bush-hammered: evenly textured, the classic finish for squares and plinths
- polished: deepens the colour, for interiors and facade details
Origin and geology
