Bone porcelain
Bone porcelain is distinguished by its unique composition that includes a significant proportion of calcined bone ash, as well as kaolin, feldspar and quartz. This formula modifies the internal structure of the clay body, providing greater mechanical strength, a soft translucency and a characteristic luster obtained by vitrifying the piece at high temperatures. Its ductility during modeling facilitates the creation of thin pieces and elaborate contours, which makes it especially appreciated for fine tableware, figures and decorative objects.
Although it requires rigorous control of temperature and firing time, its dimensional stability and response to appropriate glazes ensure smooth surfaces and finishes that enhance the brightness of the piece. Moreover, bone porcelain can be used in both artisanal and industrial contexts, offering wide aesthetic possibilities ranging from monochromatic sobriety to the application of complex decorations.Interesting Fact
Bone china was developed by the English ceramist Josiah Spode at the end of the 18th century and became a standard of quality in the British ceramic industry. Before its industrial consolidation, the search for a white, translucent porcelain prompted numerous experiments in European ceramic workshops, promoting exchanges of knowledge and stimulating innovation in the sector.Helpful Tip
When working with bone porcelain, keep in mind that its plasticity favors modeling, but it also requires special care during firing to prevent deformation. Plan the thermal curve precisely, monitoring heating and cooling times.
