Click to chat· Firing is the process of bringing clay and glazes up to a high temperature. The final aim is to heat the object to the point that the clay and glazes are "mature"—that is that they have reached their optimal level of melting. To the human eye pots and other clay objects do not look melted the melting that occurs is on the molecular level.

Click to chatDuring the firing process the manganese colouring agents undergo several chemical changes resulting in manganese compounds that are insoluble in water. They have varying degrees of solubility in weak acids. Once dissolved these compounds may migrate in solution towards the surface of brickwork.
Click to chat· Clinker bricks are produced when wet clay bricks are exposed to excessive heat during the firing process sintering the surface of the and forming a shiny dark-coloured coating.
Click to chat· Our testing showed that about 5 shrink during the drying process 1/2 during bisque firing (cone 06) and 5.5 during glaze firing (cone 6). The total of 11 is shown in the lantern picture below (before and after). We also found through out after years of firing that even with the same clay body shrinkage can vary 1-2 from batch to batch.
Click to chat· Nonuniform firing temperatures lead possibly to color variations even within a single . The value of compressive strengths of bricks increases with color intensity from low-strength light-red-colored bricks to high-resistance dark-red-colored ones.
