Reticulation & Granulation: Surface, Heat & Transformation

Explore two of the most dynamic and historically rich surface techniques in metalsmithing—reticulation and granulation—in this hands-on workshop focused on heat, control, and transformation.

Reticulation is the process of creating dramatic “mountain and valley” textures by carefully heating specially prepared metal until its surface begins to move and flow. As the metal approaches a semi-molten state, it responds to the direction and intensity of the flame, producing organic, one-of-a-kind patterns that bring energy and depth to the surface.

Students will learn how to prepare metal through depletion gilding, design and fabricate forms suitable for reticulation, and control the movement of metal during heating using a variety of torch types. Techniques for forming reticulated sheet into three-dimensional structures, combining it with other fabricated elements, and addressing finishing concerns such as patination and repair will also be covered.

The workshop will also introduce granulation, an ancient decorative technique experiencing a modern resurgence. By transforming small snips of metal into perfectly rounded granules and fusing them to a surface, students will create richly textured patterns ranging from geometric to abstract. Instruction will include forming consistent granules, preparing and applying a traditional flux, and achieving successful adhesion without disturbing the underlying design.

Through demonstration and guided practice, participants will gain a deeper understanding of how heat, material, and surface interact—leaving with new technical skills and expanded possibilities for incorporating texture and pattern into their work.
