Tylose glue or a.k.a gum glue is an edible glue that is used when cake decorators need to adhere gumpaste or fondant together. e.g for making gumpaste.
Fondant and gum paste will start to dissolve if too much edible glue is used. You can always add more if needed, but it's impossible to take.
I use edible glue for many things, from decorating biscuits with fondant / sugarpaste, to securing flowers and other decorations to fondant. Take a pea size ball of fondant, drop it in 1/8 c. or so of water, let it sit. Once dissolved (or nearly so), it's fondant glue.
