#MYTH3: CERAMICS ARE EASILY STAINED

Today we dismantle another of the myths about ceramics: Ceramics stain easily.

In any work or reform, the choice of materials is vital and their technical and aesthetic qualities are an essential factor. Precisely because of its qualities, ceramics are presented as a good candidate for all types of reforms or new buildings. On the one hand, it does not require any special care, and on the other, it is easily cleaned with any neutral detergent.

The resistance to stains in a ceramic material is highly variable depending on the type of surface. That is why standard 14411 contains a test method, called ISO 10545-14, for the evaluation of resistance to stains that can be applied to both glazed and unglazed ceramics. For all types of ceramics, a minimum of class 3 is required with cleaning method C (mechanical cleaning with a rotating brush and commercial abrasive cleaning agent, for 2 min. Washing with water and drying with a chamois).

Glazed ceramic materials are easier to clean because stains have nowhere to nest. However, what many do not know is that unglazed materials have a considerable influence on the absorption capacity of water or their porosity. Our unglazed materials have a low porosity, well below 0.5% of what the standard requires. Here there are no capillaries that communicate the interior pores and, consequently, the staining agent can only occupy the external pores, where hardly any dirt remains, probably being the most hygienic alternative in any space, especially in kitchens or bathrooms.
