One of intrinsic disadvantages of enamel coatings is the presence of large gas inclusions and pores formed as a result of the gas bubbles breaking during melting of the frit. Moreover, pores reduce enamels mechanical strength and lower the chemical resistance as a result of a decrease in the effective thickness of the protective layer and could lead to the erosion of enamel. However, gas bubbles prevent the development of cracks and increase the elasticity of coating layer.
