The sprued wax copy & cup are then dipped in several layers of a liquid "slurry" mixture and sand to encase the wax, which then dries and hardens. This ensures that the wax pattern & sprues are fortified by an outer ceramic shell that becomes the final mold after the shell is fired and the wax has melted out.

Shell Burn-Out or "Flashing"

The flashing/burn-out stage eliminates all wax and moisture from the ceramic shell.  The shells are placed into the furnace and heated to a point where the wax is melted away, leaving a hollow ceramic shell that is ready to accept the molten bronze. The shells are now ready for casting!

Jamey Kearl

Portrait - Jamey.jpg

Jamey has made a great impact at Baer Bronze by incorporating his background in the manufacturing and design fields. He got his bachelor's degree in industrial design which has helped him bring a creative approach to producing bronze castings.

His passion for the guitar has allowed him to perform in countries like Brazil, Argentina, South Korea, China, and all over the US. He loves burritos, Star Wars, Star Trek, the Lord of the Rings trilogy, and his wife and 5 children. He would like the world to know that he is aware that he should have been a ballerina because he has the grace of a swan.

Joe is our resident "Jack of All Trades" and is skilled in pretty much every area of the bronze casting process. He is particularly skilled at mold making, slurry dipping, and quality control. Joe's art background includes sculpting, pottery, drawing, and working with clay in its many forms. 

Nathanael Stuver


Nathanael has quickly made an impact at Baer Bronze in the slurry, casting, and metal prep departments. He has an impressive background in welding & fabrication as he is trained in Gas Metal Arc Welding (MIG) and earned the Blueprints, Symbols, and Thermal Cutting Process Certificates from Mountainland Technical College (MTECH).

He loves sushi and all Italian foods, can quote all of A Knight’s Tale, and was initially surprised by his patronus, but now proud to say it is an English Stoat. Nathanael has a love of reading, particularly fantasy novels and recommends Harry Potter, the Sword of Truth series, and The Dresden Files.
