Using Hand-made Tiles My hand rolled tiles are thicker than most commercially produced ones which are made of pressed clay powder and not wet clay.
My tiles are approximately 12mm or 7mm in thickness and this needs to be taken into consideration when mixing with other tiles. Commercial floor tiles are generally thicker than wall tiles for strength. My encaustic tiles being about 12mm in thick, work well along side terracotta quarry tiles, for example.
I would recommend using the services of a professional tiler when installing more than a small panel of hand cut tiles due to their slightly irregular nature.
Due to the nature of many Terra Amada glazes (their lead content for example or crackled surface), many creations are not generally suitable for food use. This means they not suitable for work tops, for example but are perfect for splash backs, walls and floors.
A limited types of our tiles will be suitable for continued exposure to water. This is due to the crackle nature of some of the glazes. While generally suitable for sink splash backs, some of my tiles may not be sealed enough for showers or for any use in bathrooms which remain damp for long periods after use.
My tiles are suitable for indoor installation. I have had tiles outside my studio in all weathers (Southern Portugal) for several years and would also be confident of them surviving outside in this mild climate. However, they have not been tested for outside use in cold climates, where water may penetrate and after freezing, expand and crack the clay.
I would be willing to send samples for testing (over-wintering) to interested parties in Northern Europe.
