Back with another simple PR, and figured I should make an issue.
The tags in the spouting recipes did not use any namespace (for example, raw_ores/platinum), causing Minecraft to interpret the tags as under the minecraft namespace, e.g., minecraft:raw_ores/platinum (obviously nonexistent). What should have been used is the c namespace, c:raw_ores/platinum.

Fixed by #15.

Thanks for testing and fixing!
