Complete Guide to Tesserae: Materials, Types & Choosing the Right Pieces


Before flow, before design, before expression…there is one essential decision:

What are your mosaics made of?

Tesserae are not just pieces you place—they determine how your mosaic feels, reflects light, ages over time, and ultimately… how it lives in the world.

In this lesson, you’ll learn how to confidently choose the right tesserae for any project, understanding their materials, properties, and behaviours.

No guesswork. No overwhelm. Just clarity.
