Rust – Ultimate Furnace Guide + Oil Refinery (Updated 2021)

Intro

This guide allows rust players to effectively smelt resources in:

• Small Furnace
• Large Furnace
• Oil Refinery

This will prevent resources from overflowing while producing to maximum capacity.

• 5 wood per 1 metal ore
• 2.5 wood per 1 sulfur ore
• 10 wood per 1 high quality metal ore
