Why limestone gets made into trim at all
Milling a profile takes time proportional to how hard the stone is, and limestone is the softest of the common building stones.
It cuts cleanly, holds an edge well enough for a pencil or a liner, and does not blunt tooling the way a granite does. That is why a limestone trim range exists where a granite one largely does not, and why the stones here are the softer beds rather than the dense ones.
The sizes are small because the stock is solid
2x12 leads, with a narrow 1/2x12 group, and the thicknesses run to a full inch and 11/16.
An inch of solid limestone in a 2 by 12 piece is a substantial object for something that only shows two inches of face. The depth is not decorative: it is what is left of the block after the profile has been cut into it, and it is why a stone trim piece weighs what it does.
Honed throughout
Every piece in this range is honed, which is the finish limestone is normally supplied in.
The stone will take a polish and rarely holds one, because its grain is open and comparatively soft. On a trim piece that matters more than on a field tile, since a molding sits at an edge where hands and furniture reach it, and a polish that wears unevenly along a single line is more visible than one that wears across a floor.
The stones behind the names
Bosphorus, Britannia, Galala, Ceaser, Thala and Jerusalem run through this small range, in beiges, grays and browns.
Galala is Egyptian, Thala Tunisian and Jerusalem comes from the hills around that city. They are quarry names rather than color descriptions, and on a trim range that matters because a molding has to match a field tile from the same stone, not merely a similar tone. Limestone tile gathers the flat formats in the same stone.
Matching trim to field tile
The whole purpose of a stone molding is to finish an edge in the same material as the surface it borders.
A near match is worse than a plain contrast, because a molding sits directly against the field tile along its entire length and the eye compares them at the closest range anything on the wall gets compared. Where the exact stone is not available as trim, a metal profile is the more honest answer. Moldings is the trim page for every material.
Where limestone trim goes
The top edge of a wainscot, the cap of a backsplash, the junction where tiling meets plaster, the nose of a step and the border of a panel.
Anywhere a limestone surface has to stop and be seen stopping, which in a stone room is most edges. Limestone mosaics and limestone pavers carry the other formats.
