Diamond Converter (FORGE)

I made this mod just for me and my friends but i want to share it because maybe one of you wants something like this too. the models are not good (never done that before) and the concept is simple.

Its my first ever little Mod that i have created.

You can craft 3 new Items, 2 of them are placeable blocks.

1. Hard-Diamond

- This is an item that you get, when you place one Diamond Ore (silk Touch needed) into one of the new Blocks. I explain what you need the Hard Diamonds for later

2. Diamond Converter

- This is where you place the Diamond Ore inside. You get 2 Hard-Diamonds from 1 block Diamond Ore. The Converter needs Fuel that also runs out, when nothing is inside.

- Fuel Sources are Blaze Rods, Blaze Powder, Coal Block, Coal, Charcoal

3. Convertion Table

- After you made yourself a Hard-Diamond you can place them in there, click Convert and out come 4 Diamonds. (1 Ore -> 1 Hard-Diamonds -> 2 Diamonds)

any suggestions are welcome.

keep in mind that this is my frist mod and i am new to this :D so keep the suggestions beginner friendly :D
