Speedball001050 Underglaze, White, 16OZ

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 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!

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.

Works very well

So the color is absolutely beautiful which is why I spent so much time trying to make this work for me. Im not sure if I was sent a very old bottle or this is just how these underglazes are by nature but it was extremely gritty/chalky which makes even or detailed application almost impossible. I’ve mixed it, sieved it, and tried adding gum solution, which helped slightly but not enough. When fired the resulting color is a beautiful golden yellow, nicely saturated like amaco velvets. The color is one I haven’t found in either Mayco fundamentals or amaco velvets but the consistency makes application so challenging I think it would be easier to make my own underglaze at this point. Don’t buy or you’ll be tempted to use and then spend hours wiping it off your pot cursing speedball for this crappy product…

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

I use Speedball underglazes in all my classes. I fired to cone 5 with Amaco zinc free clear in the picture I attached. I’m happy with the results. I do recommend 3 coats for an opaque result. The student wanted a wash look, so this was applied like watercolor.
