The Process of Making Mosaics
Creating a mosaic is an imaginative yet structured process, where materials and intention come together step by step. The mains steps are described in brief below.
1. Conceptualization and Design
Every mosaic begins with visualisation of the idea. This is followed by selecting the techniques that align with the meaning of the composition. At this stage, I define the overall composition, establishing the direction of movement and selecting the colour palette that supports the intended mood. Choices of materials—glass, marble, smalti, millefiori—are aligned with the purpose of the work, be it decorative, symbolic, or narrative.
The scale of the piece and the surface on which it will rest on are also evaluated, ensuring the design can be translated effectively into tesserae.
This step serves as the foundation, guiding every decision that follows in the mosaic-making process.
2. Surface Preparation
Choosing the right surface is essential, because it determines the mosaic’s stability, longevity, and the techniques that can be used. I estimate the weight of the mosaic and anticipate where it will live — indoors or outdoors, exposed to moisture— and select a substrate that can safely support the materials. Acrylic boards and cement walls offer strong, weather-resistant bases; mesh backing allows flexible or curved applications; while lime plaster supports traditional Italian methods.
3. Cutting the Tesserae
The cut of each tesserae determines the mosaic’s energy — directing the eye, shaping the flow, and defining the movement of the pattern. Every fragment must meet its neighbour with purpose; the precision of their fit creates the rhythm, tension, and emotional tone of the artwork. A mosaic breathes through these cuts — each angle a decision, each edge a pulse of intention. Thus, cutting the tesserae is one of the most refined and essential skills in mosaic-making. Tools include: hammer and hardie (traditional Italian tool), wheeled nippers and tile cutters.
Hand-held nippers and hammers coax marble and stone along their natural veins, shaping them through controlled pressure, rather than force. Glass and smalti respond differently: they break with a crisp, musical snap. Guided by scoring wheels or hardie-and-hammer, the emerging cuts break along their inner venation.
With every trimmed edge, I have often discovered the fragment’s true voice — the exact shape in which each tesserae wants to belong to the mosaic.

4. Placing the Tesserae into Pattern and Flow
Placing tesserae in straight or curved lines establishes the basic rhythm of the mosaic and sets the direction in which the viewer’s eye moves. As pieces are aligned, even the slightest shifts in spacing, angle, and tilt help define the contours, the transitions, and the emphasis within the design.
Patterns build gradually, with each tesserae supporting the next to create a continuous flow or a controlled contrast, depending on the intent. Through these deliberate placements, a mosaic gains clarity, structure, and visual movement — the underlying geometry that gives the artwork its character.
5. grouting
Once the tesserae are placed into a design, they need to be made permanent using grout. Grouting with epoxy is the popular method of sealing a mosaic. Alternatively, I also use resin to fill the spaces between tesserae. Both these methods protect the mosaic permanently.
Grout colour dramatically influences the final appearance—dark for drama, light for softness, or tinted for harmony. Specially available grout coloured powders can be mixed with epoxy or resin. As the epoxy grout settles into the interstices between the tesserae, it deepens colours, draws out hidden luminosities, and binds the tesserae into a unified field of strength. Its silken spread glides into every contour, embracing each piece without overtaking its voice.
When cured, the mosaic surface gains a quiet resilience — a sheen that speaks of durability, intention, and care.
In this final act, the mosaic is not just completed; it is awakened into permanence.
