By the way, I've learned a lot about making mosaics and it is even easier than making stained glass windows. I encourage more dialists to use this beautiful medium more. You don't need expensive tools or lots of experience to make a mosaic sundial. If you go to the bottom of the Technical Information Page on the SGS website, you will find a description of the two basic mosaic techniques (the poured concrete and the grout methods).
Well. I've found in my city a shop that makes laser etching on granite mosaics and some kind of thermical photo-transfer on common ceramic tiles (15*15 cm) from *.jpg pictures or Autocad drawings. I suppose there must be other shops like that in your cities (mine is at www.momentoseimagenes.com). Final results seen quite spectacular, but I do not know if this is suitable for sundialing: for instance, I suspect that the fixing-bath layer that protects the photo-transfer easily degradates with sunlight (the man at the shop says that it'd possibly degradate, but very slowly). As regards to laser etching on granite, it seems suitable, but the kind of granite he uses is rather grayish and it has just an average contrast. Have any of you had any experience with shops like that? Regards, Anselmo Perez Serrada -
