Abstract: An enamel paste composition comprising: glass frit; a pigment; and an organic carrier medium; wherein the glass frit comprises at least two glass frits including a first glass frit and a second glass frit, and wherein the first glass frit has a larger particle size and a higher glass transition temperature than the second glass frit. Also described is a method of forming an enamel coating comprising: depositing the enamel paste composition on a substrate; and firing the enamel paste to form an enamel coating on the substrate, the enamel coating comprising a heterogeneous frit microstructure with particles of the first frit embedded in a matrix of second frit.
