Using glass as a base to create your mosaic allows you to experiment with the transmission of light, creating a new dimension to your mosaic. You are also only limited by your imagination as bases can include vases, bottles, jars and tables.
Suitable adhesives include:
Weldbond Glue - When bonding glass tiles to a glass surface, use Weldbond sparingly if you require a crystal-clear bond. Any whiteness indicates the curing process is not complete. Clear Silicone - Use plenty of clear silicone, pressing down to ensure there are no air bubbles when using transparent glass or tiles.
The glass must be completely clean prior to applying any adhesives. Rub the surface down with methylated spirits prior to applying glue.
Tips when using transparent tiles & glass
Any whiteness in the adhesive indicates that the curing process is not complete (applies to Weldbond not silicone). Do not start grouting until the adhesive is completely clear.
If you are intending on grouting you need to make sure that there are no gaps where glue can seep under the tesserae.
It is a balancing act between getting a crystal clear finish and making sure you have enough adhesive applied so that the grout does not seep underneath.
If you are using a glass vase etc you need to take into consideration that you may see the back of your mosaic through the opposing sides.
A good result takes time; don't rush the laying of the tesserae
