John,
Your posting has perfect timing for my SGS project. Given that my 40 square plain glass window is already in place in a second floor bathroom, I will be creating the stained glass sundial as a framed piece to then be screwed in place on the outside of the window. I like the magnetic attachment of the gnomon idea. My thinking is akin to the approach you suggest (mosaic pieces first then poured in grout lines), only in reverse: create the structural lines to the sundial and art design then put in the stained glass using pourable colored translucent resin. The grout lines could be created by routing a sheet of ¼ outdoor sign board. So my question to the readers of this list is whether anyone has experience and recommendations on using any pourable resins and how the material/colors hold up in the face of weathering/UV exposure? Larry Bohlayer Concord, NC [email protected] _____ Its called Glass on Glass Mosaics. These are small pieces of stained glass that are stuck onto a larger pane of clear glass with a clear waterproof adhesive (like clear silicone). The spaces between the glass are filled with grout. What a great idea! Light would shine through the clear stained glass mosaic tiles, just like a traditional leaded glass window, but without the lead. It would definitely work for an indoor stained glass sundial design! A stained glass mosaic indoor sundial! You could make them on an existing window or on a piece of framed glass as a window hanging. See examples here: http://www.flickr.com/groups/1114...@n25/ Just imagine using this for sundial windows. I cant locate any literature or websites on this simple technique, but I image that they are made by placing a drawing of the design behind the pane of clear glass. Then you put a glob of silicone on each little piece of stained glass and stick it to the clear glass. Let it all dry for 24 hours, then fill in the gaps with grout. Attach the gnomon to the window frame or to the glass. Simple! And you dont have to solder anything! Oh, by the way, on a related subject, Ive been thinking about a neat way of firmly attaching a gnomon to a glass sundial that would prevent the glass from breaking if something bumps into the gnomon (i.e. a window washer or house painter) You could attach a gnomon that has a flat steel base to the outside of the glass by placing a magnet on the inside of the glass. Ive already tested this and it works great! If somebody bumps into the gnomon, instead of cracking the glass, it simply falls off and you just stick it back on. This method of gnomon attachment is especially easy to do with a perpendicular rod gnomon since it just has one point of attachment just put a flat steel base on the rod that will attract the magnet. Simple! No drilling, nuts, washers, or soldering needed! John L. Carmichael Sundial Sculptures 925 E.
