Just wanted to briefly post here about our upcoming schedule for our Science Sunday gatherings at 3PM. We’ve got a couple of great ones coming up including a collab with Creative Arts to do Shibori tie dye with indigo. Please do register on the calendar if possible as that helps with planning. Thanks!
Feb-02-2025 - Dye Diffusion and Anodizing Aluminum
Various thicknesses of oxide were obtained on Ti by applying different voltages to give multiple colors on a simple wire “DMS.” Blues and yellows and purples were easily obtained but we did not have the setup to easily achieve the high voltages necessary to get a uniform green colors. We were only able to get a tiny speck of green that was visible under a microscope.
Aluminum anodization was demonstrated including the etch, anodize, dye, and sealing steps. It was found that of all the cheap RIT fabric dyes we purchased only the yellow dye seemed fully compatible with the process. The other colors did not have good take-up into the oxides.
