Heat anodizing titanium: a smart, practical caution

Summary for heat anodizing titanium Discussion

Heat-anodizing of titanium is discussed as a possible low-cost way to color necklace chains more evenly, but the answer warns that it is unlikely to be more consistent than electrical anodizing. Joe Davisson asked what temperature range would produce colors, whether a toaster oven or kiln could give a full color range, and whether heat would improve uniformity on complicated parts. The reply from Luck & Regards says that humidity differences, heat-up and cool-down times, and other variables make heat anodizing hard to control, while electrical anodizing can produce a more exact color when voltage is controlled. Rather than recommending a specific temperature range, the answer suggests searching the site for many existing threads on anodizing titanium and on achieving consistent color. No books are recommended in the excerpt, and no firm heat-anodizing process is endorsed.
