What would be the best glue for use outdoors?

[j b]

I am making a landscape decoration which is wood and will have recycled clear red glass glued to it to sparkle in the sun. Do not want to use gorilla glue since this turns white when it activates. Anyone have any ideas on what might be another type of adhesive that dries clear and will not detract from the sun sparkling on the broken glass?

Clear silicon will do what you want and not detract from your art work good luck

How about a clear silicone adhesive, like they use for aquariums?
