I trying to make sticker on the transparent bottle - but i couldt figure out - how to mix shaders by mask? I place the sticker with help of UV. I can make the bottle completely glass like - or non glass but with sticker.

    Also never use the output of a shader as a factor for a mix shader –  Mar 19 '18 at 15:57

Ok, sure. Before posting this question a play a lot with my file, and was very close to solution - but every time something was not perfect :) In some cases i receive good combination, but some part of sticker was transparent and as inside glass. Anyway i was not quite sure - of what is wrong. After you reply - i found issue with my sticker - it was not exported as i expecting. I attach the difference. For the below right version - i add white non transparent background. So i can control this transparency :)

Difference in alfa channel Nodes for material - glass and sticker Then i adjust materials and nodes as read it in links - i catch idea in right way.

Here is corrected scene
