Soda-lime Glass vs. ASTM B817 Type I
Soda-lime glass and ASTM B817 type I belong to fundamentally different material chemistries. Soda-lime glass is a ceramic material, while ASTM B817 type I is a metal. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 15 material properties with values for both materials. Properties with values for just one material (20, in this case) are not shown.
For each property being compared, the top bar is soda-lime glass and the bottom bar is ASTM B817 type I.
