I always screen my glazes anyway.

They sell 3 types
Ceramic Grade-which is plenty fine
Granular –which looks sort of darkish
I have been using ceramic grade for 30 years as I go thru lots
The brands have changed over the years but its all been ceramic grade for me.
I just check both my bags and they are really fine powder.
Your supplier may have only two kinds

Thanks for the responses. I'm looking at making a smooth glaze so the milled would work the best. But, I've also been interested in adding to a glaze to add iron spots to it. I think I will buy the ceramic grade and screen it to take out the larger pieces to use later.
I don't know if you are familiar with Dansk Pottery. They make a high end stoneware dinner plate in Albany slip colour[brown] and a white matt that has speckles. They are fired in oxidation in an electric kiln. [I think]. Potters add speckles to their glazes to get that stoneware reduction effect. You can use granular rutile, and you can also use granular illmanite. Don't quote me, but I think 2% would give you the effect you are looking for.I do not use these techniques in my own work, but remember them from art school.Good luck.
