I was told to post this idea on the forums, so here I am. 

If you don't like reading long posts, then leave this page now. It's a long post.

Thanks to "the_new_powder99999" for some of the properties! :)

OBSIDIAN is not just from Minecraft, It's real. It can eather be very brittle and weak or extremely strong. Just like IRL OBSD would be made by quickly cooling LAVA. However, The Hardness will be determined on what type of lava is cooled. For example, Molten STNE would make weak OBSD, and Molten TTAN will make strong OBSD. When OBSD Breaks, it will turn into POBS (Powdered Obsidian). The weight of POBS is determined on it's Life. Also, OBSD's Heat Resistance would be it's TMP. It's original melting point would be between TTAN and TUGN. It would also melt like GLAS. It will react to PHOT as if it was QRTZ and GLAS put together in a checkerboard pattern. Some PHOT would be reflected, and some would go through. Since glass is sharp when broken, POBS should be able to damage any Stickman by 1 Life per second. Even if no one makes OBSD and POBS, I would like GLAS to be able to hurt STKM. I never saw anyone who can walk on broken glass without getting hurt. Also, Like GLAS, OBSD and POBS would not be affected by ACID. Since TMP is heat resistance, TMP2 Would be it's hardness, so it would be easier for the Moderators to make it strong depending on what kind of lava was cooled. I really hope they make this, It's a very good idea! It's not useless in ANY way. We need a strong material that can still be destroyable. TUGN can withstand ALOT of heat, but it can be broken easily, also, many other kinds of materials can not be affected by pressure, but melt or burn easily. OBSD may seem overpowered, but we need something like this. Please comment and try to get the Mods to make this! :) 

This is my first forum post! :)
