G3806F - Fluid melt clear
Taken from https://insight-live.com/insight/share.php?z=gbcM8HXmX2 via digital fire
I like this clear over underglazes, as it is a cone 6 clear that is designed to stay fluid at firing temperatures for a while to let out any offgasing bubbles from the underglaze. Microbubbles from offgasing make underglaze designs appear cloudy or gray, this keeps the colours a bit brighter. That link has a variety of different recipe versions, most of which include additives for color I don't use in the clear version for dipping.
