This is an Astrolabe in progress. I used a blow forming rig I made to form the dome after engraving on the GF in med clear acrylic. I was worried about how the engrave would effect the shape but it turned out perfect, very happy! The inlay is rub n buff antique gold.

For those of you unfamiliar with the process it is basically a pressurized heater that blows the acrylic out thru a die like a bubble. I am attaching a move and pics of the forming for anyone interested.
