I was so happy with the results of this underglaze. When I looked into Speedball, they are going for high quality products at an affordable cost and I would say that they have achieved this! Here's a picture I took of a project I made for my prima. This is using the Emerald underglaze with an aqua celadon over the top. Happy potting!

I'm still a beginner at all this, so I don't know all the terminology. This works as expected. It makes a nice base. The color is light.

This is a great underglaze, I have not had any issues with it sticking to the kiln shelf and the color does not burn out at cone 5 with a ten minute hold! I have only used it on little loafers so I cannot attest to other clays.

I generally paint with acrylics, but I always like to try different mediums in search of a new effect or a good value. I love the color of burnt orange, but applying it straight from the container onto your art surface is not going to result in a burnt orange color. At best, it is a pale desaturated orangish yellow. I can only assume that firing it on clay deepens the color intensely.

Good results so far, easy to brush on and good results at Cone 6. I know color is subjective and vary due to clay bodies, but I find the color is well represented online to results in real life.

This underglaze is smooth and subtle, easy to apply and great for detail work. It comes with a good amount for the price and the container has a fair bit of space up top for mixing (pro or con). One star off because it arrived unprotected and the container was bend in, making it not stackable.

Speedball has some really nice glazes, and this is one of them. Really love the light blue color. Looks amazing. Plus, so easy to work with, my 8-year-old was evening using it. Can't be happier.
