General Mechanics registers a set of industrial fluids, each with a chemical formula, temperature parameter, and acid/base classification. Every fluid has a source block, flowing fluid, and a bucket item. Fluid properties such as temperature are used by machines and chemical processing recipes.
Acidic fluids (Sulfuric Acid, Hydrochloric Acid, Nitric Acid) are hazardous. Handle them carefully in piping systems and avoid uncontained spills. Machines interacting with acidic fluids may require corrosion-resistant components.

Fluid Buckets

Every fluid has a corresponding bucket item (e.g., Crude Oil Bucket, Sulfuric Acid Bucket). Buckets stack to 1 and return an empty bucket when used, following standard Minecraft bucket behavior.
