Mosaic Course

Lesson 1 • Tools and Studio Setup

Catalogue essential cutting, adhesion, and grouting tools and configure a functional workspace. Proper setup prevents injury and supports efficient workflow.

Lesson 2 • History and Cultural Origins

Survey mosaic traditions from ancient Mesopotamia through Byzantine and Roman periods to contemporary practice. Context informs design decisions throughout the course.

Lesson 3 • Health, Safety, and Sustainability

Apply dust control, eye protection, and chemical handling protocols specific to mosaic materials. Sustainable sourcing and waste reduction practices are introduced here.

Lesson 4 • Materials Overview and Selection

Identify glass, ceramic, stone, and mixed-media tesserae and their properties. Material choice directly affects durability, aesthetics, and technique selection.

Lesson 1 • Scoring and Snapping Glass

Execute controlled scores on vitreous and stained glass using wheeled cutters and running pliers. Consistent pressure and angle are the foundation of clean breaks.

Lesson 2 • Shaping Smalti and Specialty Glass

Cut smalti and fused glass using traditional hammer-and-hardie and specialised nippers. These materials require adapted technique due to their density and opacity.

Lesson 3 • Tesserae Quality Control

Evaluate cut pieces for edge consistency, size uniformity, and surface integrity before use. Quality control at this stage prevents design failures during installation.

Lesson 4 • Cutting Natural Stone

Apply hammer-and-hardie and wet-saw methods to cut marble, slate, and pebble materials. Stone cutting demands greater force control and safety awareness than glass.

Lesson 1 • Opus Styles and Their Effects

Compare opus vermiculatum, regulatum, palladianum, and sectile and select styles for specific design goals. Each opus creates distinct texture and visual rhythm.

Lesson 2 • Composition and Visual Flow

Structure focal points, balance, and movement using andamento lines and tesserae placement. Composition decisions are made at the design stage, not during installation.

Lesson 3 • Colour Theory in Mosaic Context

Analyse how grout colour, tesserae spacing, and material reflectivity alter perceived colour relationships. Mosaic colour behaves differently from paint due to optical mixing.

Lesson 4 • Designing for Material Constraints

Adapt designs to account for grout joint width, tesserae size limits, and substrate shape. Constraint-aware design reduces rework and material waste.

Lesson 1 • Substrate Types and Properties

Evaluate wood, cement board, mesh, terracotta, and glass substrates for weight, porosity, and flex tolerance. Substrate choice determines adhesive and installation method.

Lesson 2 • Surface Preparation Techniques

Clean, prime, seal, or score substrates to maximise adhesive bond strength before laying tesserae. Skipping preparation is the leading cause of mosaic failure.

Lesson 3 • Indirect and Double-Indirect Methods

Assemble tesserae face-down on paper or mesh for later transfer, enabling off-site fabrication and precise installation. Indirect methods suit large-scale and outdoor commissions.

Lesson 4 • Direct Method Adhesion

Apply tesserae face-up directly onto the substrate using back-buttering and spot adhesion techniques. Direct method gives immediate visual feedback during laying.

Lesson 1 • Cleanup and Haze Removal

Remove excess grout in stages using damp sponge, dry cloth, and chemical haze remover without disturbing joints. Timing cleanup correctly prevents surface damage.

Lesson 2 • Grout Types and Selection

Distinguish sanded, unsanded, epoxy, and furan grouts by joint width, exposure, and chemical resistance requirements. Wrong grout type causes cracking or staining.

Lesson 3 • Mixing Grout Correctly

Measure water-to-powder ratios precisely and achieve correct consistency to prevent shrinkage cracks and weak joints. Consistency is tested by slump and spreadability.

Lesson 4 • Sealing and Curing Grout

Apply penetrating or topical sealers after full cure to protect grout from staining and moisture. Curing time varies by grout type and ambient conditions.

Lesson 1 • Mixed-Media Integration

Incorporate non-traditional materials—beads, shells, metal, and found objects—alongside standard tesserae. Mixed media expands expressive range and requires adhesive adaptation.

Lesson 2 • Three-Dimensional Object Mosaics

Apply tesserae to curved and irregular three-dimensional objects such as pots, frames, and sculptures. Curved surfaces require tesserae shaping and adhesive flexibility.

Lesson 3 • Project Critique and Iteration

Evaluate completed projects against design intent using structured critique criteria and revise one element. Critique builds self-assessment skills essential for professional growth.

Lesson 4 • Geometric Panel Construction

Design and execute a flat panel using opus regulatum and a limited palette to reinforce precision cutting and layout. Geometric work exposes joint consistency issues clearly.

Lesson 1 • Developing a Personal Style

Analyse influences, experiment with signature material combinations, and produce a cohesive body of work. Personal style emerges from deliberate experimentation, not accident.

Lesson 2 • Opus Sectile and Pictorial Inlay

Cut and fit large, shaped stone or glass pieces to form precise pictorial compositions without grout joints. Sectile demands the highest cutting accuracy of any mosaic style.

Lesson 3 • Byzantine Gold and Smalti Work

Apply traditional Byzantine techniques using gold smalti, angled setting, and reflective light manipulation. Gold work requires precise angle control to maximise luminosity.

Lesson 4 • Large-Scale Panel Fabrication

Plan, section, and fabricate multi-panel mosaics designed for architectural installation using indirect methods. Large-scale work requires modular planning and seam management.

Lesson 1 • Mosaic Conservation and Repair

Diagnose common failures—delamination, cracking, staining—and apply appropriate repair techniques. Conservation knowledge extends the lifespan of both new and historic mosaics.

Lesson 2 • Portfolio and Professional Documentation

Photograph finished works, write project descriptions, and assemble a professional portfolio for commissions and exhibitions. Documentation is the primary marketing tool for mosaic artists.

Lesson 3 • On-Site Installation Procedures

Prepare installation sites, apply panels or direct-lay tesserae, and grout in field conditions. Site variables require adaptive problem-solving not needed in studio work.

Lesson 4 • Client Consultation and Briefs

Conduct needs assessments, translate client goals into design briefs, and manage expectations through the project lifecycle. Clear briefs prevent scope creep and disputes.
