Describe the bug:
Create is a popular mod that revolves around (no pun intended) using rotational power to automate processes through multi-block contraptions.
One feature is called bulk blasting. This involves using a fan behind lava which can push items and smelt then simultaneously.
Bulk blasting can be used to smelt clay into terracotta, this recipe also appears in the REI interface. It seems this is instead creating smooth clay.

Versions:
Minecraft version: 1.19.2
Using FTB Legend of the Eyes, so subject to whatever version they use.

To Reproduce:
Steps to reproduce the behavior. Format it as a numbered list of steps.

1. Basic bulk blasting setup: Fan (requires rotational force) - Lava - Block to stop item
2. Drop clay between lava and end block.
3. Clay blasted into Smooth Clay

Expected behavior:
Clay blasted into terracotta

but that's more an issue on create's behalf, as there are no differences in furnace and blast recipes in bulk blasting

this same issue annoyed me, so I created a little datapack that lets you craft / mix smooth clay into terracotta.

not as good as actually fixing the bulk blasting compatibility, but it makes it usable now
