ABSTRACT OF THE DISCLOSURE
A formed ceramic body is produced by a
method which includes the steps of producing a batch
of ceramic material, forming a tile from a first
portion of that batch, slipping a second portion of
that batch of ceramic material to render that slipped
second portion flowable, applying a coating of the
slipped second portion of the batch to the tile, and
firing the tile and coating thereon. The tile is
further made stain-resistant by grinding up the
second portion of the batch of ceramic material to
reduce the grain size of that second portion relative
to the grain size of the first portion of the batch
forming a tile, prior to slipping that second portion
and applying it to the tile.
