This 5" x 7" hinged box is 3" tall. The top of the box has a layer of Kaolin Clay laid on the lid surface. This is a Seattle historic landmark, the Fireboat MV Duwamish, built in 1909. I took the photo while she was at her mooring on Lake Union in Seattle, Washington. In her day the Duwamish was as fine a fireboat as existed in the US with the capacity to pump water at what was then a furious rate of 3,000 gallons a minute. Her specifications are still admired in the world of fireboats. She was even designed to be able to ram a vessel in order to sink it if the fire was becoming too dangerous to even consider fighting with water alone. She is retired now and on exihibit outside the Museum of History and Industry (known as MOHAI) and the Center for Wooden Boats on the south end of Seattle's Lake Union.
This is a great example of what I can do with a photo if you want to do a custom engraving for yourself or as a gift.
These engravings are done on an archival Mason Board surface that has been coated with a thin layer of white Kaolin Clay. I manipulate the photos digitally to reduce them to line art and then run that file through my laser engraver. The dark lines in the image is where the laser has burned away the clay, revealing the dark Mason Board underlayer. The surface can be watercolored and is quite durable. I also use this material as the basis for the Encaustic Beeswax art pieces I offer.
