These seem to work well for brushing glazes whether the bristles are fine or coarse, stiff or soft. The key to their utility is the shape. An ordinary brush, when dipped into glaze, pulls together - minimizing the total load it can hold and the breadth of stroke it can make. But these stay fanned. Each bristle has access to more glaze and thus the brush can deliver more. The fan shape also assists in spreading the glaze evenly over the surface, after all, that is the purpose, spreading evenly not decorating. A fan brush can be dipped and brushed in rapid succession, delivering a lot of glaze to the surface. And, these brushes are much easier to clean. Of course, these only work if the glaze contains enough gum to retard its drying and gel enough to stay in place. These were purchased at Michaels, they are high quality and inexpensive.
