Learn how to finish your rough casting with all of its unwanted gates, sprues, and runners.
About this Class
Learn when to remove specific gates and sprues, and see how to finish the casting by grinding, texturing, and polishing to a desired finish (a separate class may be needed if machining is required). A media-blast cabinet may be used to get the desired texture. It’s also possible some blemishes will need to be filled using a TIG welder. Finally, you’ll learn how to apply a patina of your choice to achieve the finished look that appeals to you.
Finishing the casting is the third of three basic steps of Foundry Arts:
1. Make the pattern
2. Form the mold and pour metal to create the casting
3. Finish the Casting
BARN offers related casting classes including The Basics of Metal Casting (online), Pattern-Making for Casting in the Foundry where you learn how to make patterns used to produce a working mold, and Metal Casting in the Foundry where you make molds from patterns and pour molten metal into the mold to form the casting. A foundry casting event - Guided Open Studio - is available to those who’ve attended Metal Casting in the Foundry or who have demonstrated competency in the foundry. Our goal is to host this event each month, so check the calendar. Registration is required for all Foundry and Casting events.
Jeff Oens - A widely renowned sculptor with bronze artwork exhibited in prominent art collections and public displays across the United States and Canada, Jeff is best known for his outstanding wildlife sculptures. But his portfolio also includes human figures, mythical creatures, and other diverse subjects, ranging in size from miniature to monumental. Many of Jeff’s sculptures can be seen around the industrial park on Three Tree Lane.
Frank Wurden - While getting his BS Electrical Engineering degree at the University of Washington, Frank also obtained a BFA degree with emphasis in life drawing, sculpting and foundry art working with green sand, CO2 sand casting, investment casting, and ceramic shell casting. Sculpture materials were clay, foam, wood, or wax for the patterns, and casting in aluminum, bronze and stainless steel. Frank says it’s been many years since he's actually done casting, so it’s great fun to get back into it! “I totally enjoy the entire process and look forward to helping other people do the same.”
Mario Oblak - Mario honed his passion for casting metal with BFA (University of Washington) and MFA (Rhode Island School of Design) degrees in sculpture. Creating, designing, and building in different materials and mediums is a joy, but working in liquid metal is “it” for him. Mario feels “casting is a magical process that requires patience, skill, labor, and teamwork, with the results both satisfying and permanent.” By sharing his knowledge and experience, Mario wants to help others explore, learn, and develop skills so they can see their ideas come to life.
