Example of the Burnished Bronze Finish of a Cosanti Windbell: The unassembled bronze-cast bells and their bronze-cast components are steel-brush-buffed with a high RPM wire-wheel, in order to achieve a lustrous burnished finish. While still unassembled, burnished bells and components are initially heated in an oven, then subsequently flame-treated with a torch, in order to result in a varied surface mottling of metallic golden bronze highlights and iridescent shimmers of coloration. The colors are typically not brilliant, but rather subtle, and may range from yellowish-greens to greenish-blues, and from magenta to purplish hues. Once the burnished bronze bells are assembled, an acrylic spray coating completes the finishing process, making the burnished bronze wind-bells resistant to oxidation. When subjected to the outdoor elements, the burnished bronze finish will gradually dull and darken in time, somewhat like that of a tarnished penny. Due to the varied results, associated with the burnishing/heat-treating process, any burnished item ordered and thus received, will vary from the sample photo.
