My tongue piercing experience: discussing materials

After my tongue’d healed up I was able to experience the pleasure of purchasing new piercings. This is what I learned about materials (I’m not a professional so correct me if I got anything wrong)

Surgical stainless steel: It’s what you get pierced with usually. It looks flattering and shiny. The bad thing about it it’s that it’s harder than your teeth. It means that if you’re not careful enough, you can bite on the balls and chip your teeth.

Titanium: If you are allergic to nickel the piercer shouldn’t use steel. Titanium has a much lower nickel content, therefore this is the material your piercer might use to pierce you.

Bioplast: It’s a new thing on the market. Piercings made of bioplast come in many different colours. They are flexible and comfy. And if you bite on the balls they won’t ruin your teeth. It’s better to break the piercing than your teeth, right?

Acrylic: I’ve heard many bad things about it. It can harbour bacteria, cause infections, break down  and start releasing toxins. Yet, it’s one of the most popular piercing materials. Acrylic balls come in various shapes and colours and they are extremely cheap. I’d say it shouldn’t be a problem if it’s not something you wear daily. If you end up wearing acrylic, I suggest you to purchase a bar made of one of the materials above and only use balls made of acrylic.

I ordered my piercings online from bodycandy.com. Most of them are pretty cheap and there are many colours and materials that you can choose from. I got free shipping and even 15% off, which I think is a great deal.

This is my collection now. A bioplast retainer, a stainless steel piercing that I got at my local piercing studio, two acrylic-balls piercings and two bioplast piercings. One of the bioplast ones is in my tongue now and it’s super comfy!!

You can check out the whole healing process on my blog.

Take care! x

Txch This Week: Smartphone Screens from Butterfly Wings, Humans Infected the Pacific, and Nature’s Own Genetically Modified Sweet Potatoes

This week on Txchnologist, we learned about a breakthrough in artificial photosynthesis and revelations in materials that could mean safer, greener plastics and massive energy savings in building airplanes.

Now we’re bringing you the highlights from the week, along with other news we’ve been following in the world of science, technology and innovation.

Title: Phototropia

Category: #smartmaterial #bioplastics #electro-active polymers

Author: Computer Aided Architectural Design, ETH Zurich

Year: 2012

Url: https://vimeo.com/materiability

Description: Phototropia is part of an ongoing series on the application of smart materials in an architectural context and was realized in April 2012 by the Master of Advanced Studies class at the Chair for CAAD. The project combines self-made electro-active polymers, screen-printed electroluminescent displays, eco-friendly bioplastics and thin-film dye-sensitized solar cells into an autonomous installation that produces its required energy from sunlight and - when charged - responds to user presence through moving and illuminating elements.

Test Compost Session: BioBag: Remember when I composted the BioBag?  Here is a little piece I found when doing the transfer.  After testing different bioplastics in my composter I’ve come to a conclusion about how they compost: bioplastics break apart rather than decay.  I guess breaking apart, shredding, fracturing are all means of disbursement but it is different than the decay that an apple or meat undergoes during decay.

I started composting the BioBag on 10/7 and this photo was taken on 11/8.  One month passed and this plastic was mildly intact.  I’m sure it broke down far better than a regular plastic bag, but I truly wonder how it would break down in the bottom of some landfill, compacted by time and earth, sealed from air. 

I bet a bird would love this to make their nest.

BioPlastics in Landfills a Bad Idea

According to University of North Carolina researchers, biodegradable products such as compostable service-ware do more harm than good when they end up in landfills. The study, published online May 27 in Environmental Science & Technology, points to increased interest in the use of biodegradable materials because they are believed to be “greener.” But when they end up in a landfill - as a large percentage of these products do - the materials degrade anaerobically to form methane and carbon dioxide.
