Real name Steve but that name was taken on the forum. Used Middle name. Call me Steve or Scott, doesn't matter.
Ahhhhhh. Scott......Some conversations are simply timeless, like fine wine!
Besides, the concept of patenting the burning of a brick or denim is counterintuitive enough that no one new to the forum would ever imagine it. I am still in awe of the concept.
I am currently waiting on the acceptance of my patent for exhaling, and my second patent for inhaling. I was gonna do both inhaling and exhaling as an entire process but figure if I do them separately I have the process bottled up with some flexibility built in on my part. They are patent pending so far and looks like smooth sailing!!! Once it goes through, Katy bar the door!!!! <grin>

900x600 80watt EFR Tube laser from Liaocheng Ray Fine Tech LTD. Also a 900x600 2.5kw spindle CNC from Ray Fine. And my main tool, a well used and loved Jet 1642 Woodlathe with an outboard toolrest that helps me work from 36 inch diameters down to reallllllly tiny stuff.
I attempted to test the validity of your process which you are attempting to patent. I does not work! the pump must first be primed prior to exhaling. so your patent is incomplete and thus will be rejected.

I have had success engraving letters in bricks and then re-lasering with black powder coat fill.

How messy is it with your laser, Bill? Do you get a lot of debris? Any pics?
Jeff, Dave and the rest of you:
Is anyone here interested in a patented procedure for laser engraving lawyers?
Sort of a modern scarlet letter only on their forehead for a start.
Warning: they tend to squirm a bit when the head is put in the engraving field.
OSHA specifications are followed: eyes covered with safety glasses, no anesthesia required,
just play a recording of your state's ethics code, puts them out for hours.
Wasn't bad mess wise. Took forever to get a decent depth. I had to run it at 1% speed 100% power. Then I applied powdercoat twice at 100% speed and 10% power (I believe). Gave the test piece away before taking any pics. Will try to do another in the next few days and post.

Bill, at that speed could you possibly make a decent wage selling these bricks as a fund raiser? Seems like you'd have to sell them at a retail cost to recoup your laser time. I bought a few pavers from Laser Sketch to give it a try. I thought I might try to push a fund raiser towards my church. We moved into a new church this past weekend and have some plenty of acreage for some walking paths. Perfect for some engraved bricks. I see some fund raising possibilities for me (if it's worth it).
20140703_184535~2.jpg As promised, here's one I did with powder coat. This is one of those 1/2" thick (or so) fascia bricks. I'm using it for a larger project. Ran this one twice at 5% speed, 100% power, 600 dpi. Wound up having to apply the powder coat twice. No patent applied for yet

Have you tried using coloured glass powder? My friend suggested I try it, I just need to get my hands on some.

Powder coating powder is very fine, kind of like dust. Wonder if you mixed with water and applied as a paste? I recall it sets at about 400 degrees F. Harbor Freight used to stock in the stores.
