PyramidHeart

Earthy, chalky, and damp-mineral. Porcelain clay (kaolin) before firing smells of the earth — wet, mineral, slightly metallic, with the specific chalky quality of white clay fresh from the ground.

Scent

Earthy, damp-mineral, and chalky. More specifically 'clay' than generic earth — the mineral purity of kaolin is cleaner and whiter than dark soil. The dampness adds a freshness. The chalkiness gives a dry, powdery quality even in the wet state.

More mineral and less organic than soil. Drier and chalkier than wet stone. Cleaner and whiter than terracotta clay. The kaolin-specific quality is a white, clean earthiness.

The Full Story

Porcela in clay (kaol in) is a fine, white clay composed primarily of the mineral kaolinite. Before firing, it is earthy, damp, and mineral — the scent of clean earth. This raw state is more aromatic and more 'real' than finished porcela in, which is essentially scentless.

The scent of wet kaol in includes geosm in (earthy), petrich or-type mineral notes (iron and aluminum oxides interacting with water), and a particular chalky-powdery quality. When the clay dries, it becomes more chalky and less earthy. The smell of potters' studios — wet clay, drying clay, and kiln-fired clay — captures the full spectrum of kaol in's aromatic life.

In perfumery, porcela in clay is the earthier, more tactile counterpart to the finished porcela in concept — raw material versus clean object.

Did You Know?

Did you know?
Kaolin gets its name from Gaoling (literally 'High Ridge'), a village in Jiangxi province, China, where the white clay was first extracted for porcelain production during the Tang dynasty. The village's clay deposits were so thoroughly mined over centuries that the original source is now largely exhausted.

Extraction & Chemistry

Extraction method: Not extracted from clay. The note is reconstructed from earthy (geosmin), mineral-chalky, and damp-mineral elements.

In Perfumery

Porcelain clay is a concept note providing earthy-mineral, tactile character. It is the raw, pre-fired counterpart to the finished porcelain concept. Built from geosmin (very low doses), mineral-chalky elements, and damp-earth accents. Useful in artisanal, ceramic-studio, and earthy-clean compositions. More grounded and less abstract than the finished-porcelain note.
