This is a super simple server-side mod that adds quicker furnaces using Polymer.
Textures are taken from IronFurnaces.
This is a Fabric mod targeting servers.
While it will also work fine on clients, you probably want to use a true port like this one instead.
Make sure to enable Polymer AutoHost on your servers.
