are tylose and gum tex the same thing? I can't find tylose where I live, but I can find gum tex.

They are not the same, but they are very similar. If you can only get your hands on gum tex and don't want to order tylose by mail, gum tex will work fine. I used it all of the time for about 2 years before I finally switched to tylose. Are you sprinkling it into your fondant to make your fondant firmer?

Yes, I was going to sprinkle it in fondant to make it firmer, but I also found a recipe for gum paste and needed tylose. I just wondered if the gum tex would work.

Hmm...I don't know about that part, as I've never used it to make gumpaste. I think there is a recipe for gumpaste on the gum tex canister though.
