I asked this question w/in a thread, too. . . looking for a glue with some body (so it helps keep the skinny figure upright) to use to anchor a small figure in a very small glass jar for a snowglobe necklace.
Hmmm, I thought you were asking about gluing a clay base with partly-embedded items to the base of a snowglobe (cap, etc.)... for those kinds of glues, look in the other thread. Gluing a figure directly to glass rather than partly embedding it in clay would require a waterproof glue meant for glass and plastic (see link below), or possibly a resin.
but what kind of glue do you like for polymer clay?
Which glues will work with polymer clay depends a lot on the particular application you're wanting, and what kind of surface the clay will be glued to.
This page has loads of info on all the glues we generally use with polymer clay, and which may work best for each application:http://www.glassattic.com/polymer/glues-Diluent.htm
My daughters & I make a lot of little toys that frequently break
Two things here... how to fix
polymer items that have broken, and how to make them so they don't break in the first place.
So first, if you use a strong brand of clay (like Premo, FimoClassic, Kato, and possibly FimoSoft... iow, not Sculpey
), the baked clay won't be brittle and easily breakable (those stronger clays will just bend
if stressed rather than snapping off or chipping, especially in any thin or projecting areas).
Secondly, the join needs to be strong any time you're connecting two raw pieces, or adding one piece to another (like an arm to a body perhaps). This can be done by making a large
area of connection between the two, or by using an armature inside the two pieces connecting them together as one (as simple as a bit of toothpick or piece of wire), using certain "glues" like liquid polymer clay, or just leaving the pieces in contact overnight before baking, etc.
You might want to read more about making strong joins, using armatures in those ways and others, and making simple clay figures successfully on these pages:http://www.glassattic.com/polymer/glues-Diluent.htm
