To really capture the authentic aged appearance that antique Delft tiles are known for, we offer our clients the option of adding characteristic crackled finish to their newly made Poarte tiles
The process is actually quite simple, and we don't need much equipment. The most important tool is the torch. We carefully heat glazed surface of the tile and then cool it down with water, creating quite a bit of steam along the way.
The quick change in temperature causes the glaze to crack, creating fine lined patterns. This crackling is a natural occurrence in Delft tiles that develop over time, but with this process we simply speed things up a little.
Once the cracks have formed, we rub the surface with a thin, dark powdery liquid. This settles into all those cracks, making the lined pattern more visable.
After a few wipes with a towel, the process is complete and the tiles have that characteristic aged, crackled finish. And because the glaze cracks naturally, every crackled tile is unique. đź’™
