Bronze is a metal alloy which appears pinkish / gold because of its copper & brass content.
The bronze firebowl is 1/8” thick for the 45” model, and 1/4” thick for the 54” and 68” models. Over time, bronze will naturally patina to a dark, tobacco brown color within a few weeks, then ultimately to a grayish green.
Note: There is some chance of surface staining, but much less than rusted steel. Patination time and color is dependent on local atmospheric conditions.
Copper is a ductile metal with a soft pink, peachy color.
The copper firebowl is 1/8” thick for the 45” model, and 1/4” thick for the 54” and 68” models. Like bronze, copper will immediately begin to patina to a dark, tobacco brown color and ultimately to a bluish/green color.
Note: There is some chance of surface staining, but much less than rusted steel. Patination time and color is dependent on local atmospheric conditions.
Corten steel is also called “weathering steel” and is a structural / architectural / sculptural grade of carbon steel.
The corten steel Firebowl is of 7 gauge material, or slightly over 1/8” thick. Corten steel will begin rusting almost immediately, and will stabilize within a few months and stop rusting.
Note: Corten steel will leave rust streaks on the surface below it; we ecommend mounting the Firebowl on a bed.
Mild steel is industrial grade carbon steel, and the most economical of the Firebowl materials.
The mild steel Firebowl is of 10 gauge material, roughly 1/8” thick. Mild steel will begin rusting almost immediately, and continue rusting slowly for decades.
Note: Mild steel will leave rust streaks on the surface below it. We recommend mounting the Firebowl on a bed of gravel if surface staining is a concern.
Stainless steel is non-corrosive steel alloy and will remain silver in color.
The stainless steel Firebowl is of 10 gauge 304 stainless which is more pewter in color than kitchen stainless.
Stainless steel will not stain the surface on which it is placed.
