Mosaic Artist | Teacher

Sandra Robertson — affectionately known as the Wizard of MOS — has been conjuring mosaic magic for more than two decades from her Brisbane studio, OzMosaics. A fearless experimenter and beloved teacher, she blends smalti, slate, china, glass, and the most unexpected treasures into artworks that shimmer with story and soul. Students call her the China Whisperer, the MOSaic Guru, and the mentor who can turn a broken plate into pure possibility.

Her studio is a playground of colour, texture, and invention, where beginners and advanced artists alike discover the joy of mosaic art. From Pique Assiette to 3D sculptural builds, from hydrangeas and flowers to portraits, murals, and mixed‑media masterpieces, Sandra’s imagination knows no limits — and she shares it all with generosity, humour, and heart.

Through The MOS — Mosaic Online School, Sandra opens her creative universe to the world. Her courses guide you step by step, helping you build confidence, master techniques, and find your own mosaic voice. She champions sustainability, celebrates imperfection, and believes every shard carries a story worth telling.

A mentor, adventurer, innovator, and award‑winning artist, Sandra continues to push the boundaries of mosaic art while cheering on everyone who dares to begin. With her at your side, you don’t just learn mosaics — you discover the magic of making.
