Your Question

Applied energistics 2 uses some resources that are not accepted by Macerator in GregTech CEu.
Is it possible to add some recipes from applied energistics 2 to GregTech CEu?
Namely:

• 1 Fluix Crystal -> 1 Flux Dust
• 1 Certus Quartz Crystal (There is an analogue in GregTech CEu. But it is impossible to craft Charged Certus Quartz Crystal from ae2) -> 1 Certus quartz Dust (There is an analogue in GregTech CEu. But it is impossible to get Silicon from it from Applied energistics by remelting.)
• 1 Sky Stone -> 1 Sky Stone Dust

This would probably fit under Gregification mod by right, but AE2 is so integral to GT that I think it’s worth implementing into CEu itself

I'm also the one who wants this to be implemented in GTCEu, with an additional suggession (1 Certus Quartz Crystal -> 1 Charged Certus Quartz in Electrolyzer, GregTech 5 seems to have implemented this recipe) for a new recipe.
