the forming and handling equipment from sticking and or adhering to the composition during the forming operation the enamel composition includes a crystallizable glass frit portion and a seed powder the crystallized glass frit portion includes precursors from which zn 2 sio 4 can be crystallized upon firing of the enamel composition the seed powder causes at least a portion of the precursors to crystallize upon firing such that during firing at least a part of the crystallizable glass frit yields crystallized zn 2 sio 4 the enamel composition also preferably includes bismuth oxide in order to help further ensure that no sticking and or adhering problems develop during the forming operation application_number US 79938991 A description an enamel composition made in accordance with the principles of the present invention for use in producing a layer of enamel or an enamel finish or band upon a section of glass at typical glass forming temperatures comprises a crystallizable glass frit portion and a seed powder the crystallizable glass frit portion includes precursors from which zn 2 sio 4 can be crystallized upon heating or firing of the enamel composition the seed powder causes at least a portion of the precursors to crystallize upon firing such that subsequent to firing at least about 2 percent by weight of the crystallizable glass frit portion yields crystallized zn 2 sio 4 formed by the precursors the precursors include zno and sio 2 the zno comprises from at least about 30 percent by weight.
