I added a page to display my custom smelting recipe. But it doesn't display correctly.
Could anyone tell me where goes wrong?
(The recipe can work in minecraft world properly. And my minecraft version is 1.12.2)

p.s. Sorry for the texture of the ore. I haven't done it yet.

These are my code.

You are registering your smelting recipe during init and not the recipe registry event

So what exactly should I do?

Oh! I found what goes wrong and I solved that.
Thanks for your help.
