Laser Engraving

My wife's cousin and I have been working on a co op project involving using a laser engraver and dichroic glass. Here is an example of a necklace I just finished up over the weekend. Is anyone else doing this type of work?

Cool.  How does that work?

Sorry about posting so late. Basically I start with a blank piece of dichroic glass which has a metallic coating. My wife's cousin then laser engraves the image. Once I get it back I put a piece of clear glass on top of the dichroic glass to protect the image then  I fire it in a kiln that reaches about 1500 degrees. After it's cooled I glue a necklace bail to the back side of it. That has to dry for about 24 hours then it's ready to wear.

Very cool!

 

Is the laser engraving similar to the 3D images in crystal blocks that you can buy in gift shops/malls?

I am not sure if it's the same process or not. I will have to ask my wife's cousin if he knows. Let me get back to you on that one.

The 3D images in gift shops is a point cloud and the laser goes to each point based of the density of the point cloud and send a millisecond bust of laser into that point it fractures the crystal a couple microns. You can do that with Verisurf pretty easily. Just need a laser scanner and you are good to go.
