Low Expansion Glass-ceramic vs. Granite
Low expansion glass-ceramic belongs to the glass and glass-ceramics classification, while granite belongs to the natural stone. There are 15 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.
For each property being compared, the top bar is low expansion glass-ceramic and the bottom bar is granite.
