Adhesives for Gluing Glass to Glass
There are many different types of adhesive for permanently attaching glass to
glass, with different characteristics and suitability for different
situations. Here's a list of the main types.
1. Silicone
Silicone glue, widely available from most
hardware or DIY stores, is both inexpensive and easy to use.
The clear varieties dry clear and resist yellowing. These are
often used for attaching feet to fused pieces, but their flexibility
makes them practical for holding larger pieces of glass together as
well. They're one of the best glues to use for outdoor
installations, and have the advantage that they can be removed with
a razor blade. The GE Silicone II brand is one of the best.
2. Glass epoxies
Although most epoxies do not work well for
glass -- they tend to yellow in time -- there are some epoxies that
have been specially formulated for glass. One of the best
known of these is Hxtal, an ultra-clear epoxy that does not yellow.
This is an expensive product and it must be mixed precisely (a scale
is essential). It also requires a long curing period (as long
as a week), but if applied properly it forms a secure and
long-lasting bond.
3. Ultraviolet glue
Ultraviolet (or UV) glues can also provide
a secure, long-lasting bond. They're easier to use than
epoxies, but they do require that the glass be transparent.
The curing process involves exposing the glue to an ultraviolet
light source, which can range from sunlight (for some varieties) to
a long wave ultraviolet lamp.

how best to use adhesives to ensure a strong and lasting bond.
