Granite vs. Low Expansion Glass-ceramic
Granite belongs to the natural stone classification, while low expansion glass-ceramic belongs to the glass and glass-ceramics. 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 granite and the bottom bar is low expansion glass-ceramic.
