Review of Popular Bead Coatings and their Durability

May 18, 2018

 

We have all been there.  You find a gorgeous new beading pattern or video and can’t wait to start it.  Then, after selecting the colors, spending over an hour hunched over your bead mat, and sharing your accomplishment on your favorite online beading group, the finish on your beads starts wearing off!  You want to scream!

This is an experience far too many of us have had.  While it is impossible to predict exactly how each particular coating will wear over time, there are some finishes that have a better track record than others.  I recently conducted an experiment of my own to test the durability of some of the popular coatings in both Czech Glass and Miyuki Seed Beads.

THE EXPERIMENT

I began by selecting a number of colors of DiscDuo bead.  I selected this bead for it’s flat surface.  This allows for more of the bead to have contact with my skin allowing for maximum wear.  I also selected Duracoat Galvanized Champagne and Galvanized Dusty Mauve to test the durability of Galvanized compared to Duracoat Galvanized.

I used peyote stitch to create my project.  Using 4 of each color DiscDuo, I worked my pattern keeping each set of 4 together.  This allowed the color blocks to be compared easily from week to

week.  The Miyuki seed beads were alternated in stripes at the beginning and end of my project and throughout the peyote stitch.  The length of the experiment ran for 30 days, wearing the bracelet about 5 days per week (and occasionally in the shower).

THE RESULTS : CZECH COATINGS

After the 30 days were up, I documented the bracelet for the last time.  I compiled the photos that best showed the progress over time.

TOP OFFENDERS

1. Capri Gold Full: This finish, on a jet color bead in this case, wore off the fastest of all the colors tested.  After only 2 days of wear, it was obvious that is was coming off quickly.  After the 30 day mark, almost all of the coating was off on the side of the bracelet that had been worn facing my skin.

2. Amber:  Amber’s change was less noticeable since it was over a crystal bead and the contrast was less striking.  The wear was slightly less than the Capri Gold, but still showing signs of wear at day 2.

3. Sunset: Crystal Sunset was the third color to start showing signs of wear.  Similar to the Capri Gold and Amber, it was almost completely gone from some beads at the end of 30 days.

4. Crystal Sliperit Matted: It was a surprise to me that this color wore off as much as it did.  The other matte color I used, Vitrail Matte, did not show any signs of wear.  At the end of 30 days, the color seemed to have rubbed off the surface, but some had remained in the crevices of the textured (matted) surface.

5. Aztec Gold: The previous colors mentioned seemed to gently rub off over time, however the Aztec Gold was more susceptible to getting scratches.  At the end of my experiment, there was some noticeable wear from rubbing against my skin, but very little in comparison to Capri Gold, Amber, or Sunset.

 

THE RESULTS: MIYUKI GALVANIZED COATINGS

As I expected, the Miyuki Duracoat Galvanized coatings showed much less wear than the Galvanized.  On the Galvanized seed beads, the color at the end of 30 days was either

flaking off or completely off all the beads.  The color did hold up better in areas where there was less chance for beads to rub against each other or my skin.

The area of most wear was the loop I created for the button closure.  The Galvanized Smoky Mauve is much lighter, or gone, on the beads of this color used in the loop.  This is most clearly seen on the bead at the very bottom of the picture to the right.

LESSONS LEARNED

While there are many factors that play into how well the finish of a bead will hold up over time, you don’t have to feel completely helpless when you select the colors for your next project.  My experiment showed that some colors were very resistant to wear.  Coatings that appear thicker and slightly matted tend to hold up well, like the Pastel Light Green, Aztec Gold, and Metallic Violet.  The Azuro, Marea, and Hematitecoatings also held up very well.  Lusters, represented by Teal and Lila Vega, did fairly well, too.

Keep in mind that it isn’t only the coating itself that is the cause of discoloration or wear.  Other factors may include:

  1. The amount of moisture to which the beads are exposed
  2. Your skins pH balance
  3. Conditions in which the jewelry is stored when not worn
  4. Exposure to sharp edges (like keys in your purse)
  5. Topical skin creams and make up you use
  6. Exposure to cleaning chemicals

Every person is different, just as every coating is different.  The chemical ingredients in each coating react in their own way to all these outside influences.  No one can predict how well a coating will wear over time, but you can learn from your own experience and reduce the wear to which your jewelry is exposed.

For those of you who want to reduce the risk of wear and discoloration to 0%, plain

opaque or transparent colors are the way to go.  The color in these beads is not on the surface, but in the glass used to make the bead.  If the bead is cracked in two, the color will be the same all the way through.  All beads start out as a transparent or opaque color, but some have coatings applied to the outside.

In an upcoming blog, you’ll learn more about the Czech coatings from a scientific point of view.  There are a few different processes that are used as well as an array of chemicals used.  Don’t worry – there wont be a test later   Understanding the meticulous, lengthy process each bead has to go through will give you a better appreciation of the final product.

Happy Beading!
