A minimally drippy aventurine glaze
Here I showed an adventurine glaze on a bowl. One observes that the aventurine sparkle is visible only on the virtical walls, and the bottom of the bowl has a crack and has all the attractiveness of brown plastic.
The glaze flow into the bottom of the bowl created the appearance seen above.
Below I show another picture of the original glaze, and below that, a modification of that glaze.
The aventurine effect is as pronounced in the modified glaze as in the original. In addition, the modified glaze is more viscous, and shows a more evenly distribution of the aventurine sparkle. In particular, the adventurine bits show in the bottom of the bowl as well as on the side walls.
The irregular blob shape at the foot of each bowl, is a leaf print.
