I have only just started using this mod pack and was wanting to craft the mirror however the recipe doesnt seem to work any help would be great. using 1.16.4

The crafting recipe is one glass pane on top of one gold ingot. See mirror.json.
Let me know if you still have problems

Even with the recipe it isn't working for me. I can't make the mirror.

You're not using the "mineshafts and monsters" mod pack by any chance, are you?
I just learned that some of the Greek Fantasy recipes are changed by that modpack.

Ooh, yes I am! That explains it then, but is it just different or is it not possible to make it at all?

I wouldn't know. You would need to ask the modpack maker.
