Here’s a short, personalized review you can use: ⸻ I’ve been using the Speedball White Underglaze on my pottery pieces, and it’s been a great addition to my studio. Once I gave it a good stir and thinned it slightly, it brushed on beautifully—smooth and opaque in just two to three coats. I love using it for sgraffito and surface designs where I want crisp, clean lines, and it fires to a nice bright white under clear glaze. It holds up well through bisque and glaze firings, even at Cone 6. Definitely a solid staple for any potter looking to add reliable white detailing to their work. The only concern that I feel obligated to state about this product is that if you’re going to apply a clear glaze over it, you definitely should be using Speedball clear because it does not seem to like when I use another brand’s clear over it and will occasionally bubble or crack if I don’t use the Speed ball clear.. I called Speedball to ask them about this problem and they confirmed that this is a known issue.
