Quartz (SiO2)
Quartz is one of the most widely used minerals in ceramics, its main component is silica (silicon dioxide), which is essential for vitrification. Quartz, being rich in silica, contributes to the formation of a glassy structure during firing, which improves the resistance of ceramic pieces to moisture and abrasion.
In addition to its role in vitrification, quartz plays an important role as a degreaser in clay bodys. By acting as an agent that reduces the amount of organic material in the mixture, quartz improves the workability of the clays, preventing them from being too sticky or difficult to handle. This facilitates the formation and shaping of the pieces, and also improves their structural stability.
On the other hand, being a highly refractory mineral, quartz increases the ability of the pieces to resist intense heat without deforming or cracking, which makes it a crucial component for technical and refractory ceramics, such as tiles or bricks exposed to high temperatures.
Quartz also helps prevent deformation during firing, providing dimensional stability to the pieces. This is especially important in the manufacture of large ceramics or complex shapes, where precise shape control is crucial.Interesting Fact
Quartz is one of the most abundant minerals on Earth, and its purity and particle size directly affect the properties of ceramics. The finer the quartz, the better its integration into the ceramic mixture.Helpful Tip
Be sure to use good quality, well-sifted quartz to avoid unwanted inclusions in your pieces. Also, balance its use with other ingredients in the mix, as too much quartz can increase the brittleness of the pieces after firing.
