Barberton Earth & Fibre

Raw materials from local land

Every pigment, clay body, paper sheet, and charcoal stick originates in the soils, fallen timber, and wild plant fibres of the Makhonjwa Mountains.

Geological Sourcing

Raw Barberton terra cotta

Weathered ancient shale deposits along mountain gullies yield rich plastic clay. We dig raw soil, soak and sieve out coarse roots, then wedge the clay on stone benches for hand-building and wood firing.

Sieving raw local clay removes gravel while preserving natural iron oxides, resulting in deep terracotta bodies that bind without commercial additives.

Fibres & Fabrics

Sheet pulling and frame sizing

Paper Vats

Beaten bark and reed sheets

Wild mulberry bark and invasive river reeds are boiled in ash water, beaten to pulp with wooden mallets, and pulled through deckle frames into durable rag paper.

Canvas Stretcher

Linen frames and rabbit gesso

Heavy cotton duck and raw linen are stretched across mortised timber frames, then sized with warm hide glue and white chalk gesso for long-lasting archival tooth.

Minerals & Ash

Mulling ochres and burning wattle

Earth Colours

Sieved ochre on glass slabs

Mineral rocks and hillside earths are crushed, levigated in water tanks, and ground on glass slabs with linseed oil or gum arabic to yield brilliant natural artist paints.

Charcoal Sticks

Kiln-charred willow and wattle

Fallen wattle branches are trimmed to size, sealed inside airtight steel canisters, and slow-charred over open fires into deep velvety drawing charcoal.
