Above is an image of the type of variation that may occur between two tiles of the same design and size. The differences may occur for a variety of reasons:
Their being painted by two different artists
Their being located in different parts of a kiln during firing, whereby one tile was fired slightly higher than the other, causing the glaze to spread out slightly more than the other
They may be from two lots painted months apart, where the artist will paint slightly differently.
Also, with solid color tiles and molded pieces, slight variations may occur in shade from lot to lot. The deep cobalt color is the most susceptible to this, but variations are by far the exception and not the rule.
Additionally, the cobalt blues applied to decorated tiles varies in darkness according to the thickness of the application of the glaze. The thicker the application, the closer the color approximates our cobalt field tile. The thinner the application, the closer it approximates our blue field tile.
The image show above is by far an exception – most decorated tiles have differences between them that are much less apparent to perceive. Please do take into consideration however the nature of this product when sampling and purchasing.
