In 2005, Marilena Patronicolas invited the distinguished porcelain artist Helga Mueller-Harren to Greece, marking the beginning of a series of international seminars that brought new inspiration to the local porcelain art scene.

Helga Mueller-Harren is celebrated for her refined mastery of porcelain painting and her poetic approach to classical motifs.

Her work reflects both technical excellence and a deep sensitivity to color and form. Through Marilena’s initiative, Greek artists had the rare opportunity to experience Helga’s teaching firsthand—discovering the grace, discipline, and emotional depth that define her artistic philosophy.

The seminar became a milestone event, remembered for its atmosphere of creativity and cultural exchange, and for the way it bridged traditional European craftsmanship with contemporary Greek artistry.
