: You want to use the "smoothest" texture as possible. The only reason to use textured glass is so you cant peel off the pieces easily. Dependning on how you plan to display your project (or what you plan to use it for) it may not matter. Using a textured glass will create grooves, cracks, (MORE SURFACE AREA) for the caulk to adhere to. If the glass is too textured (i.e. rippled etc, then the pieces will never set straight, they will lean, be crooked, etc. Silicone caulk is good. Its pliable, until set, easily cleansup and if you buy a quality silicone caulk is guranteed to bond for 50 years plus. In reality you could use play-do (cause once you grout it in it shouldnt go anywhere LOL)...but the caulk is good and helpd things adhere to the glass.

: : I am new at mosaics so please excuse the stupid question! My pattern book says to do glass mosaics with a glass backing, the backing must be textured glass, and to use silicone caulk. What do they mean by textured glass - etched? bumpy? rippled? and why won't regular smooth windowpane glass work as a backing? Also, is the silicone caulk the best adhesive?
: : Thanks for your help!
Hello--
I have used smooth glass as a foundation for mosaic pieces that are designed to be put in a window or in front of a light source. I didn't find it necessary to use silicone caulk; but I did use liquid nails CLEAR for small projects. I prefer the way this dries completely clear for when you want light to transmit through the piece. Once the piece is grouted, it really is secure, and I had no problem with slippage or peeling off. Best of luck!
