MATERIAL / TEXTURE
One Aji stone, many expressions: split surfaces, polish and rust tones
There is more to a surface than its colour.
TABUCHI ／
Separate surface finishes from natural colour variation, and choose Aji stone with light, texture and setting in mind.
01
Separate the material from its finish.
Split and polished describe ways of finishing a surface. Sabi, or rust-toned stone, describes a natural colour character rather than a finishing technique.
Fine-grained and medium-grained refer mainly to crystal size. Separating the stone itself from its treatment makes a design brief clearer.
02
A split surface changes with the light.
Uneven faces catch light and create shadows. Frontal light and low light from the side reveal different aspects of the same piece.
When considering a wall or a freestanding stone, look at viewing distance and lighting together. Check protrusions and edges wherever people may touch the surface.
03
Polish brings reflection into the picture.
A smoother face directs attention to mineral grains and patterns, but may also reflect fittings and its surroundings.
The mottled character known as fu differs between stones. A small sample cannot show the full composition of a large piece; inspect a broader area where possible.
04
Rust tones are a material choice.
Brown tones can arise from iron-bearing constituents in the stone. Their intensity and distribution vary naturally and are separate from the chosen finish.
These colours can relate to timber, planting and earth, or add warmth to a restrained interior. Check the actual material, since photographs and conditions of use can alter how it appears.
05
Decide how much variation to retain.
Differences in grain and colour become more noticeable when pieces are placed together. Decide whether the aim is a consistent field or a composition that celebrates variation.
Consider the block, finish, lighting and adjacent materials together. An unusual expression can come from choices within one type of stone, not just from choosing a rare material.
06
Appearance is not a performance test.
An uneven surface is not automatically slip-resistant, and hardness alone does not establish suitability for every application. Wet floors, wall fixing and furniture contact surfaces each need specific checks.
Send a reference photograph and we can discuss whether the quality you are drawn to is colour, relief or reflection, then consider the right material and treatment.
