Raised Niobium Patterned Discs

2 comments

Anybody have any comments regarding how to best ”pad” an anodized raised patterned disc without removing the unraised background, near its edges for example? Which Micro-mesh Soft Touch pad grit typically works the best?

 

It seems just the slightest pressure in an effort to remove the first anodized background layer off the raised pattern surface also tends to mar the unraised area too. The coarser the pad, the worse it is. Seems there is an ”optimum” grit that hits only the raised pattern, leaving the background in tack, while having enough ”bite” to get the job done without overdoing it and marring the background.

 

Making a lot of scrap and little finished product.

 

Thanks again,

Rick

I've used these pads and the trick isn't so much about which grit (all will work) it's more about making sure the discs are on a flat surface and the pad is held parallel to the disc. Don't use the pads edge as it will always hit the edges and in the grooves. It also helps if the embossed parts are deep. Some shallow ones are harder to keep from hitting the edges too.

Thanks for the comments. Guess I have to work on my technique some more. However, it is nice to able to ”erase” one’s mistakes with the next etching session. I’m building quite a collection of things to re-etch!

  • I teach our fold forming classes and I read that niobium can be fold formed My concern is that with copper, I anneal it fairly often with some folds What folds can be done with it any hints? I love making pea pods by hammering on the folded curve, but I always have to anneal those before I can open them. I have this dream of nice green pea pod.
  • Hello, I feel really silly asking this question because I fear the answer is obvious and I’m just missing it, but I don’t want to electrocute myself. When you say rubber gloves are these like the kitchen cleaning gloves with latex, or do I need electrician gloves? Thank you.
  • Hello, thanks for answering my question about paint brush sparking. Now I have two questions about thermal oxidation. First, I really like the torch process and the result, so I hope your answers are the ones I want to hear. 1. I read thermal oxidation of titanium is toxic, by "releasing" titanium oxides. It was a comment on youtube, not necessarily a credible source. The titanium oxides are built up on the metal, right? Is there a known health risk of heating titanium in a closed space? I don't have a fan at my bench. I open a window in warmer weather but it is closed in winter. Is a face mask recommended? 2. How durable are torch fired colors? Is anodizing more durable? What I noticed was the torched oxidation was thicker and less prone to scratches. But if it turns gray in a month's time, it wasn't worth my time or the value of other materials. I read there are no clear coats for titanium - is that true? I am a beginner at titanium, anodizing or torching. I used flux on this pendant (I know flux is toxic) and the colors were torch fired. This is your crystalline titanium paired with a small lapis. Thnx for any advice on using torch on titanium.
