Finally fired up the blaster and this is my first attempt. It is addictive can't wait to do more. So much to learn..............

Jim,
What are we looking at?
Did you back the etched area with something black, to make it visible to the camera?

Jim,
That is a great start. You picked a great thing to etch on your first attempt. Pay special attention to the finer lines on the point scale. This will show you the limits of line thickness that can be achieved with blasting.
Did you use silicone carbide or aluminum oxide, and what grit size?

All - this is a 4" square glass block (actually a bank with plastic insert). I used 220 alum ox. I used a piece of black craft paper so the engrving shows better. It is also my first product photo in my new lighting igloo. In other shots I used a blue background but I like the pureness of the white. I photo'd some basketball trophies and this glass block and then proceeded to try and move one of the two lights and the lite fell off the tripod and a brand new, used 30 minutes, $30 tungsten bulb got broked (NASCAR talk) and my photo session came to a halt.
The graphic came with the RapidMask test kit that Photobrasive sent with my cabinet/system. I like it because like David pointed out is shows the range well with line thickness and the points in the fonts. It also gave me a little confidence right out of the box with a totally new material and process.

Jim,
I'm curious if you got any electrical shock on your forearms when you were blasting. The reason I ask is that aluminum oxide generates plenty of static electricity, enough to send a little wattage into your arms when you come in contact with the metal frame of your cabinet.
220 grit will get you some really good detail, especially if you are using it in combination with RapidMask when blasting photographs.

David,
None noticed yet but I have very limited experience so far, wonder if my foot on the cement floor grounds me out?
