Kalium Private Company

Kalium is a Greek family house of collectible glass, bringing together a family enterprise established in 1999 and the living tradition of Ukrainian glassmaking.

The story began when Nina and Nikolaos Kolpidi founded Ergopan S.A. in Greece in 1999. Today, their grandson Michail Kolpidis continues the family enterprise through Kalium P.C. and leads its evolution into a contemporary house of artistic and collectible glass. Greek Government Gazette, 1999

Kalium objects are created in Ukraine by Ukrainian master glassblowers, preserving the traditions of hand-blown glass while developing them through contemporary forms, colour and the distinctive optical qualities of potassium crystal.

The first signature collection Ova ex Kalium expresses this identity through sculptural eggs — individually made objects of glass, colour and light, conceived to be collected, documented and passed from one generation to another.

Principles

Heritage without noise.

  • Family continuity: our commercial story begins in 1999 with Ergopan S.A. founded by the family’s grandparents, and continues with Kalium P.C.
  • Made in Ukraine: Kalium objects are created in Ukraine by Ukrainian master glassblowers, carrying forward a living tradition of artistic glassmaking through skilled hand production.
  • Limited by intention: Kalium creates collectible objects and defined editions rather than anonymous mass production. The variations inherent in hand craftsmanship give each piece its individual character.
  • Made to endure: every Kalium object is conceived with an identity beyond the moment of purchase — an origin, an edition and a documented provenance designed to remain with it over time.
01 · Material

Potassium crystal

Lead-free potassium-based crystal glass defines the material language of Kalium — exceptional brilliance, vibrant colour and a distinctive relationship with light.

02 · Form

Ova, relics and orbs

Ova ex Kalium begins a broader vocabulary of collectible glass objects — expanding into relics, orbs and future limited forms — united by material, craftsmanship and proportion.

03 · Provenance

Documented objecthood

Every Kalium object has an origin, edition and identity — designed to be traceable and collectible, with records preserving its provenance and collector history over time.
