This Pebeo no drip Medium was created to easily mix with the Vitrail glass paints. This medium allows glass objects to be decorated vertically without the paint running down the object which would create an uneven paint finish
It is important to mix the colours and the medium well, while avoiding the incorporation of air (do not shake). Mix 50% of Vitrail colour with 50% of the no-drip Vitrail Medium.
