The characteristics and production method between glazed and unglazed of ceramic and porcelain tiles by firing process: A review

Abstract

This paper reviews the difference between glazed and unglazed ceramic and porcelain tiles, other than the fact that glazed tiles undergo an additional phase in the firing process. Both tiles are made of clay and burned in a kiln, but porcelain is a particular sort of ceramic. Porcelain clays have a greater density and are burnt at a higher temperature for a longer period time than ceramic clays. This makes it denser and more durable than ceramic tile. The variation in components and production process results in tiles with distinct properties. Although glazed ceramic and porcelain tiles are a little less robust in terms of density and thickness than their unglazed counterpart, they allow for a wider range of styles and colours. Some varieties of glazed tile are fired at higher temperatures than others, and therefore are harder as well. Unglazed tiles are denser and thicker than glazed tiles due to their unfinished appearance. In addition to safety, ceramic and unglazed ceramic tiles are scratch resistant. Because they have the colour of the mineral deposits from which the clay was originally mined, these tiles have a natural aesthetic. The major difference between ceramic and porcelain tiles is how it’s made. In conclusion, porcelain tiles are superior to ceramic tiles based on these reviews.
