John Sollinger

John Sollinger (Solly) is an artist and educator, based in Ashland, Oregon, USA. With stained glass pieces chaotically arranged, he produces mosaic wall-hangings that portray
plants and fire or water in realistic-to-impressionistic landscapes of Western USA forests. His techniques developed in isolation, and his visual vocabulary was sculpted by biology. Solly has earned major awards in international, mosaic and all-media competitions. He presents at mosaic conferences and offers workshops at home and overseas. In USA his mosaics have been featured in popular press, coffee-table books, trade journals, art magazines and advertisements for art organizations and competitions.
John's Classes
Learn Solly's signature fluid double reverse technique, whereby the entire mosaic is assembled without adhesive. Then it is flipped to expose the backside of the mosaic. An adhesive-covered substrate is laid over the mosaic and then the mosaic (+ substrate) is flipped a second time, exposing the front side of the mosaic. This session should particularly benefit those who enjoy stepping outside their comfort zone in search of new ways of thinking and making, those who feel that they spend too much time removing adhered tesserae, and those who wish to work more quickly and without the mess created by frequent handling of adhesives. A slide presentation, in which Solly provides an overview of the technique, will be followed by a brief demonstration and Q&A session. In the remaining time students will practice this method in at least one dry run before working on a 12 x 12 inch mosaic, using images and designs that are provided by Solly. Solly will assist those who are new to using stained glass (cutting techniques), and share his processes for choosing images to mosaic, color schemes, framing, layering, and, if desired, methods Solly employs to create an illusion of 3-D and realism.
