Trusted by Today’s Most Well Known Artists
World-renowned and up-coming artists alike are using Speedball Underglazes exclusively due to their incredible performance, value and versatility.
Ideal for detailed painting, sgraffito decoration, watercolor effects, free brush painting, screen printing and mashima decoration, the opaque underglazes are designed to perform in a wide firing range, Cone 05 – 6, and have been successfully fired to Cone 10.
Create Depth & Character
Speedball Underglazes can be used to create designs and patterns that will come through the glaze covering them, allowing for more visual depth and character. Although they are often used under clear glazes, they can also be used under other, generally light-colored, transparent glazes.
In the Studio
Speedball Underglazes can be applied to greenware and bisqueware. Colors will not move or flow during firing. For best results, apply 3 liberal coats and use with Speedball Earthenware or Stoneware Clear Glaze.
All colors are dinnerware safe when used and fired as directed, are lead-free and carry the AP Seal.

Product was 3/4 full. Unopened but not a full bottle of paint. Gave three stars for the fast shipping and affordable price.

This is not my first container of speedball underglaze but I think I will be ordering a different brand from now on. The product varies from container to container... my previous bottles were quite thick and had to be thinned this one is so thin that I swear it has been watered down. Not happy with speedball

Economical pottery underglaze

The color is very pretty in the jar. It comes out a bit more pink after it's done being fired and glazed. However, it is a great base color so adjust the skin color as needed. I think it's a great investment rather than making a skin tone color yourself and having no clue what it would look like after it comes out. With this glaze, I am able to know how it looks and modify it to my liking.Easy to paint on - very smooth. Wasn't too thin or thick. Very good viscosity. I would say this is quality underglaze, but also it is one of the first underglazes I have purchased for myself. The only other experience with underglaze I have is the ones I use at my local pottery studio. I like this glaze very much.Only giving it 4 stars because I didn't expect it to have a pink tint to it. I thought it would be more of a cream.

I used this for the bottom of my ceramic mugs to bring out my design and name. It was perfect. It didn’t stick to the bottom of my kiln plate. Yay!

I like that the bottle is the same width top to bottom, this allows even a wide brush to be dipped into the bottle easily. I use 3 coats at cone 6. The result is opaque, pure white without tints of other colors. Additionally, this white can be used in 2 or 3 coats beneath other glazes to give clean, bright results. White, red and brown clays can make glazes appear dull or "muddy", if you use this white in a couple of coats at greenware (recommended) or bisque, it's as if the glaze you apply over this underglaze has been applied to a porcelain type clay. You can use it alone or beneath other underglazes, other opaque or translucent glazes including clear. I've used this white to cone 10. If used alone to cone 10, be sure you have 3 full coats, allowing each coat to dry before applying another and if you're firing higher than cone 6, maybe add a 4th coat to be safe that you have good coverage. I've had this brown slightly in high fire, atmospheric firings such as wood fire, soda fire and salt fire. Hope helpful!

I did not get a chance to use the product as the lid was open and product dried out. It cost me $27 to ship it back. I am not happy with my expense and a non usable product. I have a photo I saved but can't submit. It shows the the condition of the package.

I should have heeded the previous reviews. This is how the jar of underglaze arrived today. No seal under the cap, though there very obviously used to be one. The underglaze itself is goopy and unusable in this state. I don't want to have to go through the hassle of reconstituting a product that should be immediately usable.I am leery of using it since it was unsealed and I don't know if what's inside is really what's on the label. Off to get some tried-and-true Amaco velvet underglaze now and hopefully get a refund on this.
