World Standards Day at BMXnet

October 11, 2011 by Brian Skellie

I am teaching Biomaterials standards for body art at the BMXnet conference in Essen, Germany this month for World Standards Day, the celebration of the birth of ISO October 14th, 1946. ASTM International will participate in the U.S. celebration of World Standards Day, sponsored by the American National Standards Institute (ANSI) on Oct. 13 in Washington, D.C. This year’s … Read more

Questionable jewelry project

October 2, 2011June 22, 2011 by Brian Skellie

Have you seen any body jewelry that made you wonder whether or not it was safe to wear?
Please add any manufacturer to this list who makes body jewelry that does not seem to meet appropriate safety standards. Our work group is collecting a list of examples for body jewelry review. You can email pictures, too. Your comments will be used in our ongoing project to help inform the public and improve body jewelry quality worldwide.

Anodizing Titanium and Niobium Body Jewelry

October 5, 2024June 13, 2011 by Brian Skellie

Sign up for the workshop with Brian Skellie

APP Conference / Online “Anodizing is Awesome!”

Previously Presented at BMXnet, UKAPP, APP, LBP, 2º Congresso Educativo para Perfuradores Corporais da América do Sul – ATPB 2013 & more events

1) What is Anodizing?

Anodizing is a process where a coating is built up on the surface of certain metals (titanium, niobium, tantalum, aluminum, magnesium and zinc) by heating, with chemicals, or by electricity. In the case of titanium, the coating that is built up is a layer of titanium dioxide. Titanium dioxide, which is also known as titanium oxide, occurs naturally on the surface of titanium. Anodizing the surface of titanium can be done by the use of heat but the results are not easily controlled. The most common method is to form an oxide layer on the surface with the use of electricity. The way that this is done is with a variable power supply in which an electrode is connected to the positive side (anode), and one to the negative side (cathode). Both are then submerged into a mildly conductive solution, thus completing the electrical circuit. The piece that is to be anodized is connected to the positive side, and that is why the process is called “anodizing”.

Nonconforming Imported Titanium

*En Español*

Some of my colleagues have already learned of this from my biomaterials presentations at APP 2010 and BMXnet conferences. This reflects upon imported jewelry, and the situations that can arise when quality controls are not normalized. So far, most of the response I get from US distributors of medical titanium alloys is for ELI material they only use domestic melts.

I’ve been talking with fellow ASTM committee members about international sourcing for F136 Ti in particular. They all only use domestic melts for ELI material from Perryman, ATI and Fort Wayne Metals for example . Therefore when companies in China or elsewhere want to make jewelry from F136 they either have to buy from a US or EU source that has a distributor in their area, eg Taiwan, or buy from an local mill melt, that quite possibly won’t meet FDA, BSI, ISO etc.

Selected freehand piercings

April 13, 2020April 13, 2011 by Brian Skellie

Here is a glimpse of a few piercings I performed during an exhibition for colleagues in New England. I enjoy sharing ideas and techniques with my peers. Let me know what you think.

My goal is an atraumatic aseptic technique: Primum non nocere

All of these piercings were performed without clamps using the STATIM 2000 autoclave, sterilized single use equipment, sterile nitrile gloves, and the titanium jewelry was anodized with the Reactive Metals Micro anodizer.
