This is the only test-sized sieve on the market that was actually designed specifically around the experience of use. We designed the product from the ground up, based on the experience of thousands of test glazes processed over the years. Sieving glazes is can be a chore, but it is an important one, and we dare say it might even be a little bit enjoyable with this sieve.
This larger size sieve does not include a spatula, but if you want to add spatulas, this is the link to the correct one, available in white only. The jar sieves are much smaller and their spatulas will not fit this sieve.

What Mesh Size is the right one?
Mesh size indicates the number of wires per linear inch in the screen—the higher the number, the finer the mesh. A finer mesh requires more effort to push material through but captures smaller particles. Ceramicists often select their preferred mesh size based on their specific needs. Generally, 60 Mesh suits general glaze and underglaze reconstitution, 80 Mesh is ideal for filtering out oolites and small crystals while breaking up colorants, and 100 Mesh provides the smoothest texture by breaking down the finest colorant particles, though it may also filter out some glaze, underglaze, or slip components.

Features
Integrated Venting and Hanging Hole
When you sieve a glaze, often a seal forms which prevents the glaze from flowing smoothly through the screen. We solved that with an impressed venting channel. You will no longer need to "burp" the glazes, which will cut down on the mess and hassle. Also, we tied that right into our hanging hole.
Features
Easy to Read
The mesh size is indelibly printed right into the rim in bold lettering, making sure you will never question which mesh size you are using. The lettering is structurally integrated so it can never fade or wash off.
Features
Stair-step Exterior
These steps have been measured to fit the openings of popular containers used in glaze labs, including lidded deli containers, 1.5 quart Mix'n'Measures, 16oz. solo cups, Glaze sprayers, and 8 ounce disposable cups.
What's the Difference Between Jar Sieves and Cup Sieves?
-
Jar Sieves
Jar SievesWe designed these specifically to lock into most commercial glaze and underglaze containers. We started by collecting as many glaze containers as we could find, and based the stair-step design on those openings.
Jar sieves are super compact, fit a 16 oz. solo cup as the largest size, and include a handy clip-on spatula for pushing the material through the screen.
-
Cup Sieves
These were designed to maximize throughput for a smaller sieve. We made the screen as wide as it could be while still fitting the popular 8oz. cup used in glaze testing. While versatile for all sorts of users, these are right at home in university glaze labs, group studios and classrooms. They work great for large deli containers, 16oz. solo cups, and glaze sprayers. We do make a spatula, available separately.
