It would be nice of you wrote down the name of the items used instead of just using the images of the items.
I don't get the recipe to work for the Experience Flask and I'm not sure if I use the right items for it.
The recipes for the other items work, but not for the Experience Flask.

Right now I use these items:

7 black stained glass - 1 terracotta - 1 Bottle o´ Enchanting

But nothing happens with these items.

Fair point, I can add ingredient lists to the recipes. The in-game recipe book also has all the recipes in as well, they're given to automatically.

You have the recipe wrong though, the glass is "Tinted Glass", not black stained glass.
