Vitrified ceramic materials are unaffected by ageing, weathering, ultraviolet radiation or atmospheric pollution.
For some restoration projects or specific design requirements, it may be more important to achieve a good aesthetic match than to achieve specific physical properties and tolerances. Each project should be individually considered.
Fixing and Cleaning
The importance of employing companies that are competent or who have years of experience in such matters cannot be stressed highly enough. All too often we see some of the finest buildings having been incorrectly cleaned, causing irreparable damage to materials. The fixing of terracotta and faience should not be underestimated. It is only with experience that their natural characteristics are appreciated. We will gladly advise on both these important matters and recommend specialist companies able to carry out such work.
