Obsidian Building Blocks

This mod adds new obsidian-like blocks, which cannot be destroyed. like reinforced glass. And mod adds craft of obsidian, and some items. I made this mod for SRP(ScapeAndRunParasites) modpacks, which don't have blast-protected blocks.

You can use these blocks in bunkers instead obsidian, and you can craft reinforced tools, it helps you to mine these blocks.

You can see mod content in the pictures bellow.
