Glass Mosaic Tile Art: Base Materials
Tesserae can be adhered to almost any kind of base material.
Making wonderful glass mosaic tile art is easy! Let me show you how.
Tesserae can be adhered to almost any type of base material. Size and weight of the finished work, and where and how the work will be displayed are the primary factors to consider when selecting your base material. Glass is heavy, so the base material must be robust enough to support the weight of the tesserae and grout. Indoor mosaics that remain dry (i.e., not displayed in steam rooms or similar environments) may be made using wood as the base. Outdoor mosaics exposed to the weather should be made with backerboard or other water-proof material.
