Shell Sanding and Polishing (More Gilding the Lily)

Since I’ve been having fun with the Dremel tool,

The hole was natural!

I decided to grind a shell I’ve had in my collection that’s not all that stunning. But, it’s a good candidate to paint into a neato necklace pendant since it’s already bleached a simple white.
In this case, I focused on sanding the INSIDE of the shell. I didn’t want to lose the nice outside ridges, but I wanted to paint the inside concave area. To do this, I needed to get rid of some of the imperfections.

I needed to make the inside smooth if I wanted to paint it

Now, we need to talk safety equipment. Anytime you are drilling, sanding, etc. with shells or sea glass, PLEASE wear:

  • Safety Glasses/Goggles
  • Mask (You do NOT want to breathe in any particles)
  • Gloves (again, particulate is not fun)

Also, I use water on my piece only while sanding and buffing it. Do not place the Dremel into the water. 

My equipment


Dipping the shell in water before sanding


I used a 150 grit sanding drum first, then the buffer

After I finished sanding and buffing (which took around 10 minutes), I rinsed and dried the shell off throughly.
Next, I put 3 coats of varnish over the entire shell before painting it. This will improve the shell’s surface for taking paint.

I love this varnish- a little goes a long way

After everything’s dried, I was ready to move on to the next stage. BeDazzling the shell….

I think this is an excellent use of time.
