A brief detour from chemistry, branching out into science in general today. This graphic looks at the different factors that can contribute towards ‘bad’ science

Perhaps if he was more diplomatic and better demonstrated his hypothesis he would have had a better response from his colleagues
What Titanium materials are best for body jewelry? My articles at http://jewelry.piercing.org/ and http://brnskll.com/shares/titanium-standards-why-not-g23/ explain that the two most effective Titanium standards are alloyed ASTM F136 and pure ASTM F67, the most common being the former as it is stronger, harder and easier to polish. Both are used for permanent surgical implants.
Is there a chemical residue left behind from your disinfectant?
“Most Sharpies have not been validated for industrial usage or for use in the sterilization conditions. There are a couple of Sharpie markers that do conform to the ASTM standard D4236 which means the product has been evaluated by a toxicologist for acute and chronic toxicity and the Safety Data Sheet (SDS) identifies ingredients as presenting any chronic health hazard, along with safe use instructions. The pens that bear the AP seal with the notation “conforms to ASTM D4236″ (see right) are the markers that may be used for labeling your packages.”

Have you ever visited a salt evaporation pond? It was enough to dissuade me from any desire to put unrefined sea salt in an open wound.
Among jewelry materials for initial piercing, glass deserves a closer look.
Understanding the hazards of handling and mixing chemicals is essential to safe use.
William Stewart Halsted, The Johns Hopkins Hospital’s first surgeon in chief, is widely credited as the first to develop and introduce rubber surgical gloves in the United States. That was in 1894, five years after the institution opened.
Now, in an effort to make medical care safer for patients and health care workers, The Johns Hopkins Hospital has become the first major medical institution to become “latex safe” by ending all use of latex gloves and almost all medical latex products.

The opportunity to explain and demonstrate anodizing titanium body jewlery to my colleagues in person is always a pleasure. For those of you who are interested, here are some of the basics. There are many other techniques, tips and tricks that I’ll be glad to help with if you have questions.
This is a follow up to the presentation the FDA made to my ASTM International committee on nonconforming imported titanium. It should have met ASTM F136 for surgical implants, however the Quality Systems at the mill that melted it were inadequate. More information from the FDA and a bit of legal analysis.
I like the idea of a single non-staining, non-toxic agent that Techni-Care represented for skin preparation, and have been trying other options. Here is some further information, a fun presentation, and some links
