Chat Online· The firing temperature also has a specific effect on the physical properties of the (weight and colour) but its effect on the size was negligible. The weight of the bricks decrease as the firing temperatures increase and the colour of the bricks became lighter from the deep reddish brown to a lighter reddish brown (Table 3).
Chat Online· Chemistry of Firing . Over the period of firing clay becomes a metamorphic rock. Clay minerals break down release chemically bound water and change into a mixture of two minerals quartz and mullite. The quartz crystallizes very little in that time remaining in a glassy state.
