Cone 6 (First Image): Clear Flux is a translucent, mobility enhancer that is intended to be layered with glazes. Cone 10 (Second Image): More movement. TIP: Clear Flux is the most fluid of the Flux products. Take care in applying on vertical surfaces. Mobility will increase along with the number of coats. Avoid application on the bottom third of your vertical ware. Can be used as a stand-alone glaze.
