I'm so glad to have found this group! I have a question about what kind of glue to use. I am an art teacher in the middle of a project with my classroom kids. Our project involves using window glass to be placed on top of my children's artwork (painted image in acrylic) and surrounding each image with mosaic tiles. My dilemma is (and has always been) the type of glue to use for the window glass, since it will be see through. I need a glue that dries clear and does not yellow after a while. What kind of glue would anyone recommend?
