Polvorador

It is a mod that adds the option to craft gunpowder in the game, adding a new crafting table and a new ingredient.
To be able to create the crafting table you have to use powder iron and wooden logs, with the new powder table you have to add zombie meat and iron nuggets one in each respective space and press the button on the table this will give a new item which is potassium nitrate, then with this new ingredient you place nine in each space of the normal crafting table and this will give you five gunpowder and that's how the gunpowder works.
This mod is recommended for use in a zombie world where crepers don't spawn and you need to have gunpowder or use it instead of creating gunpowder farms.
