# Mokume-gane (木目金)

> Mokume-gane is a Japanese metalworking process that bonds layers of different metals into one billet, then cuts and rolls it so the surface takes on a pattern like wood grain. The figure is a cross section of the stack rather than a decoration laid on top, so filing or polishing cannot remove it. It began as a way of decorating sword fittings.

- Kind: Technique · Family: Vessel and Craft Techniques · Era: 17th century–
- Mood: Technique, Luxury
- What this family collects: Techniques that inlay, lay on, or pour another material into the body of a vessel, where the process of finishing became a look of its own in each region.

## Defining characteristics

- The stripes close into rings and whorls that read like the end grain of a log
- Reddish copper, white silver and darkened layers sit directly against one another
- No two pieces from the same workshop carry the same figure, even at the same shape
- The stripes do not stop at the edge; they continue through the thickness of the sheet

## Best used for

- When a ring or a vessel should be patterned by the colour of the metals themselves, with no plating and no inlay
- When a small production run needs every piece to carry a different figure

## Composition recipe

- Typography & lettering: Keep any stamp to a single small mark. Place it clear of the strongest stripes and cut its lines finer than the grain.
- Layout & structure: The pattern is the subject, so keep the form plain. Let the grain follow the outline of the object and close the edge with one narrow band left blank.
- Material & texture: Stack sheets of metals that differ in colour, such as copper, silver and shakudo, and bond them into a single billet under heat and pressure. Gouge into the face to expose lower layers, roll the billet flat, then raise it into shape. Finish by polishing and colouring so the layers separate.

## Colour

Read off the reference works below, so a direction rather than a fixed palette.

- Ground: #C0C4C8
- The colour it is remembered by: #B87333
- Text and outlines: #3A332E

## What to avoid

Thin the layers too far while chasing a particular figure and one cut goes straight through, breaking the pattern.
