Why cold connection rivets instead of solder

Most jewellery is soldered. The join is invisible, which is usually the point. Cold connection is the opposite approach: the fastener is visible, structural, and part of the design. At Spruce Crest Path, most pieces use copper or silver rivets instead of solder, and the reason is not just aesthetic. It changes how the piece is built, how it ages, and what it looks like up close.

Selective oxidising with liver of sulphur by brush

Liver of sulphur is a standard patination chemical for silver and brass. Most jewellers apply it by dipping the whole piece into a warm solution, which oxidises every surface evenly. At Spruce Crest Path, it is applied with a fine brush, one surface at a time. The difference in result is significant, and the reason for doing it the slower way is specific to how the pieces here are designed.

How isometric grids shape the jewellery designs here

Every piece made at Spruce Crest Path starts on paper. The paper has a grid on it, specifically an isometric grid, which divides the plane into 60-degree triangles rather than 90-degree squares. That choice of grid is not arbitrary. It determines which angles are available, which proportions feel right, and which shapes can be cut from flat sheet metal without waste.

How the work is made

Measured by hand

Every template is drawn on graph paper first. Dimensions are transferred to sheet metal with a scribe, not a printer. The margin for error is 0.3 mm and that is held to.

Cold-connected and riveted

Most pieces use no solder. Layers are held together with copper or silver rivets, set flush so the surface reads as one clean plane. You can feel the rivet head if you look for it.

Oxidised selectively

Liver of sulphur is applied with a fine brush, not a bath, so only the recessed angles go dark. The raised planes stay bright. The contrast is the point.

Finished by file and paper

No tumbler, no polishing wheel. Every edge is worked by hand through four grits of wet-dry paper. It takes longer. The result is a surface that shows the direction of the work.

Small batches only

Most designs are made in runs of six or fewer. When a run sells out it is retired or reworked before it comes back. Nothing sits in a drawer waiting.

Hands at the helm

"Mika Tanigawa trained as a metalwork technician at a craft school in Kyoto, where she spent four years maintaining tools and setting up equipment before starting Spruce Crest Path in Matsumoto in 2017. She moved the studio to Nagano city in 2019. Her bench is an oak door blank on trestles that she has never replaced. She works through four grits of wet-dry paper on every edge and keeps a small notebook of rejected angles. On days off she walks the path behind the old building where the studio name came from."
