Lead-alkali-silica Glass vs. Machinable Glass-ceramic
Both lead-alkali-silica glass and machinable glass-ceramic are glass and glass-ceramics. There are 10 material properties with values for both materials. Properties with values for just one material (16, in this case) are not shown.
For each property being compared, the top bar is lead-alkali-silica glass and the bottom bar is machinable glass-ceramic.
