Glossary of tiling terms

ENCAUSTIC TILES — Encaustic tiles are a type of ceramic tile distinguished by their decorative patterns, which are not created by glaze but by using different colours of clay. The pattern is inlaid into the body of the tile, ensuring its longevity even as the tile wears down.

Originally known as inlaid tiles, the term "encaustic" is misleading. It originates from Ancient Greek and refers to a process of painting with beeswax-based paint fixed by heat, as well as medieval enamelling, which is not how encaustic tiles are made. However, in the nineteenth century, Victorians began using the term "encaustic" to describe these two-coloured tiles, as they resembled enamel work. Despite the incorrect terminology, the name "encaustic" has become widely accepted for this style of inlaid tile work.

Modern encaustic tiles are manufactured using a two-shot moulding process. The first moulding creates the inlay colour, with separate moulds used for each colour. Careful filling of the moulds ensures precise colour placement. The coloured clay is then placed face-down in a mould, which is subsequently filled with the body colour. After firing, the tiles are ready for use.

Encaustic tiles continue to be appreciated for their timeless beauty and durability, serving as a popular choice for enhancing floors, walls, and other architectural surfaces with their intricate and vibrant designs.
