Crafting with Nature: Iron Rich Minerals

Black Sands

Alongside the gold in our pans, another treasure reveals itself, one less flashy, but just as rich in character.

Black sands.

Heavy, dark, and full of story.

These mineral-rich grains are the quiet companions of gold, gathering in riverbeds and bends where the water slows. Composed of dense iron-bearing minerals such as magnetite, ilmenite, and hematite, they are far more common than gold, but no less important to our work.

Where gold gives lustre, black sands bring colour, contrast, depth, and grounding.

We collect these sands by hand during the panning process, keeping what others might discard.

The same iron-rich material can also be reclaimed from the crushed quartz tailings of the nearby Cononish gold mine. There, powerful magnets draw out the dark magnetic minerals from the finely milled stone, the same material ceramic suppliers sell as black iron oxide.

From river gravels or reclaimed tailings, the material finds the same destination: the studio.

Here we grind, sieve, and prepare it for use in clay bodies and glazes.

Its natural iron content creates:

• Freckles
• Speckles
• Flecks and texture

Subtle reminders of the rivers and mountains the minerals came from.

In high-fire glazes these iron-rich grains can rise to the surface, forming mottled or crystalline textures depending on the firing atmosphere. In clay bodies they lend a natural speckling, each pot carrying its own quiet map of the Highland soil.

But for us it’s not just about surface effects. It’s about recognising value in what is often overlooked, the darker minerals that travel alongside gold but rarely receive attention.

As with everything we gather, these black sands are part of a wider philosophy:

• Use what’s local
• Tread lightly
• Celebrate provenance over perfection

Turning what lies underfoot into something that lasts.
