Hello, I try to make this but it doesnt' work :/ :

instead of "Grains of Infinity" you need to use the internal registry name for the item, which in this case would be "enderio:item_material" with meta 20. You can check what these registry names are either by pressing f3+h ingame to view advanced tooltips, or by using something like crafttweaker which has the command "/mt hand" and will copy the registry name of the item you are holding into your copy+paste clipboard.

Anyway, the proper recipe should be as follows

<recipe type="evaporator">
<input quantity="144">dawnstone</input>
<output>
    <item quantity="2" meta="20">enderio:item_material</item>
</output>
</recipe>

I will test this on my own just to make sure that I can get this to work.

Ok, yes. It looks like the recipe I posted should work. If you have any other recipe questions feel free to ask.
