“Layered Glass Mosaics,”
with Yulia Hanansen

On Saturday and Sunday, July 30th & 31st, 2022, immediately following the opening of “Mosaics 2022: As Seen Through New Eyes” in the Foothills Art Center, the principal juror, Yulia Hanansen, taught a group of very interested mosaicists about the freedom of using tesserae in layers.  They learned how form and volume can be emphasized with “brush-stroke” tesserae, and how to create exciting flow and direction in their mosaics.

The goal of this intermediate session is to help students observe sources of inspiration allowing for the creation of their own signature textural and temporal andamento studies. Students who have some basic mosaic-cutting and fitting experience will boost their know-how by learning to analyze why they are drawn to a particular work of art by examining and “unpacking” the compositions and andamento of a variety of mosaic works. This intense observation will allow them to assess how the andamento is used to create a mood or effect, as well as some basics on composition. Students should bring one printed or emailed example of a work they want to deconstruct as well as images that are inspiring that could serve as a possible mosaic. This class will allow them to see in a new way, and to create texture that will enhance the character of their mosaics by utilizing several methods for creating tactile textures based on both a presentation and hands-on work.

Each student will execute a set of two samples based on four possible options— Shell Out, Rising Up, Pebble Waves, Detritus Assemblage. These dynamic and dimensional samples can be used as a visual reference for future works. The materials provided will be affixed to a cement board substrate with thinset. There will be explanations and instruction provided to the group at large, after which each student will receive individual attention. The last part of the class will be devoted to a group discussion and critique, if requested.
