# Glass material: object shown with strange artifacts

I have an object that I've built using many circles, and then connecting the edge loops between them. I've tried to apply a glassy material, playing with transparency values, but the problem is that the parts where there are the circles are drawn differently:

I've already adjusted the normals. How could I eliminate these artifacts?

Update

There are no faces inside the edge loops. This is how the mesh looks in edit mode:

• Try selecting all and removing doubles from W menu. If that doesn't help please upload the file, at least part of the problem model. – Mr Zak Jun 15 '16 at 19:55

It looks to me like there are still faces left inside your mesh. Like this:

What you need to do is delete those inside faces. This can be done by just selecting the center vertex of each circle and hitting X on the keyboard and then selecting delete vertices. Your final clean mesh should look like this:

Hope this helps!

• You could also select those faces with Select Non-Manifold operator from Select menu or Ctrl+Alt+Shift+M – Mr Zak Jun 14 '16 at 22:43
• It's strange because there are no faces inside the edge loops. I created some circles and united them with w -> bridge edge loops. Check my post, I uploaded a new image that shows the wireframe structure of the object. – Ramy Al Zuhouri Jun 15 '16 at 14:22
