I’ve been experimenting with embedding titanium in epoxy resin to create artwork. I’ve had limited success with heated titanium, though most colours are lost. No success with DC anodised. Is there any coating that can be used on titanium or niobium that will preserve colours so as to enable embedding? Any suggestions on alternative approaches? Cheers Phil

Is it possible to create all the colors in the Frog image below in titanium Anodized Sorry for such a large images

i’m fairly new to anodizing niobium and only use the techique as called for with a project. I don’t do this every day as you likely do in your shop. Thus, my TSP and etching solutions may be ”older” than yours at times. I can always make up fresh TSP solution in small quantities and ensure I’m always using fresh solution, but the etchant is more problematic. The way it is packaged I have to make up the whole 1/2 gallon of the 2X concentrate all at one time. (I would make smaller lots if I could divide the dry powder accurately, better yet buy it in smaller units.) I then make up only 1 cup of the 1:1 dilution for a hot etch. After use I always decant it into a heavy polystyrene (?) lidded container for reuse later. I toss this diluted solution if I notice any color tint. Sorry for the long intro ... Because my use is so limited at times, these soultions tend to ”age in place”. Are there any tell-tales to look out for as an early indicator that it is time to use fresher reagents, or explain what I’m seeing when things go differently than expected?
