<p>[QUOTE=&quot;Anabel P., post: 2788890, member: 16749&quot;]The reasoning of the bubbles fades into the air as you notice that the rust spots come out of the enamel itself.</p><p>The spots of rust are triggered at the intersections of the crackle, where they then find the space to escape. Since, as you can see, these rust spots also come out of the glaze, this means that the crackle passes through it, and where the glaze is thinner, the crackle is best seen, where instead the glaze is thicker, the crackle occurs less. Furthermore, since rust is found on both crackle and glaze, and that its oxidative state is homogeneously at the same level, this proves that the glaze is the same age as the ceramic, and therefore it is not possible that the vase was decorated later. This is a 19th century vase, not because I say so, but because it is the oxidative state of the iron oxide that affirms it.[/QUOTE]</p><p><br /></p>
