Unburned

Wood is one of the most popular building materials in Minecraft, but it has a significant drawback: high flammability. The Unburned mod solves this problem by adding fire-resistant versions of all wooden blocks to the game.

The process of creating protected blocks is quite simple. First, you need to collect special plants in the Nether and create Nether Compound from them. Then this compound needs to be bottled and used in crafting along with any type of wood. As a result, you'll get a completely non-flammable equivalent of the familiar wooden block.

All crafting recipes are available for viewing through JEI (Just Enough Items), making the process of mastering the mod extremely convenient.
