<p>A stable glaze slip formulation having a pH of above 7.5 which comprises particles of at least one glass forming material suspended in an aqueous medium containing a synthetic associative polymeric thickener which comprises a hydrophobically modified polyacrylate copolymer which forms aggregates or micelles in aqueous media, which is shear thinning in aqueous media but which does not break down under shear, the thickener being incorporated into the glaze slip formulation in an amount such that the suspension, prior to application, has a yield stress of greater than 2Pa, the glaze slip formulations, in use, exhibiting shear thinning behaviour on application to a substrate surface and on firing the thickener decomposing and/or burning out of the glaze slip formulation in order to leave substantially no residues or residual artefacts in the glaze so formed.</p> |
