I read a couple of months ago about a substance you can buy to make airbrushed fondant look "wet/glossy" like a patent effect. Im making a Marine Corp. Hat. Now when I tried to find it again, I can only find suggestions of vodka, crisco, corn syrup, etc. Does any body know the name of the stuff im talking about ? -Thanks so much!

Confectioner's Glaze, maybe? I ran across this product online when working on a gumpaste shoe. If you Google, or perhaps even on CC, you can find a recipe to make your own or it can be purchased through various sugarcraft stores.

Confectioner's glaze. You have to buy a bottle of thinner too because it doesn't come off of brushes at all.

This bow was painted with it. It's completely dry in the picture.

Oh, I just noticed you mentioned an airbrush...you wouldn't want to put confectioner's glaze in the airbrush, I don't think it would ever come out.

I've read of confectioners varnish that will give the cake a gloss. Have you tried using steam on it to make it shiny?

I don't know if you can put this in an airbrush since I don't have one, but maybe you can use the following recipe and brush it on?

I haven't tried this personally, but it's called edible varnish:

hey sorry guys....i didn't mean a glaze to go into the airbrush. I meant after it was airbrushed. I found the confectioners glaze and got the thinner too. Thanks so much for everyone's help!!!

Texas_Rose....you do such great work! How did you color your black fondant? My new dilemma is that I need a lot of black fondant. I originally thought I could airbrush white fondant black (im new to airbrush) but after trying it and getting a greenish color when practicing im thinking not. I did research and the one place I found said the only way was to purchase black fondant already colored. Any advice?

Try Americolor Super Black. If you can use chocolate fondant for what you're doing that's the easiest way...replace part of the powdered sugar with cocoa powder, maybe 1 cup or a little less, and add a bit extra water. Hershey's special dark cocoa makes almost black fondant. Other cocoa powders aren't quite as dark, but either way it doesn't take much black color to make it turn black. If you can't use chocolate, then use the Americolor super black and add it when you add the liquid to the marshmallows. As long as you get it a deep gray, it will darken to black overnight.

I forgot to mention that confectioner's glaze really stinks...you'll want to run the fan in the kitchen or crack open a window while you're using it. The smell goes away as it dries though.
