How big are the individual granules of frit? If applying Bullseye frit with a sifter, what size mesh screen will I need?



Bullseye manufactures these five different grades of frit: extra large, coarse, medium, fine, and powder

Bullseye frit granules come in five sizes: extra large (available in clear only), coarse, medium, fine, and powder. We recommend applying frit with a sifter, as there are a number of interesting effects that can be achieved.

Grain sizes range from 5.2 - 30mm; granules are retained on a 4-mesh screen.
