The pour did happen today.


Plaster investment poured with a number 80 crucible. Brownie points to any one who knows how many pounds of bronze that is. Answer in comments.

Professor Laura West, head of Sculpture at Fresno City College, has been casting iron since her undergraduate studies at Southern Illinois University in the late 1980's/early 1990's. This is where her first iron furnace was built. Professor West continued her studies at Idaho State University and then became part of the teaching staff at the Johnson Atelier Technical Institute of Sculpture before moving to Fresno, California. Although Professor West has run and built furnaces of a wide variety of sizes, types and situations, she specializes in smaller furnaces and beginner crews. Laura is known internationally for her iron casting skills. Her small tap out iron cupola which melts 100 lbs/7minutes and has been used in classrooms and workshops from coast to coast. This furnace alone has seen over 30,000 pounds of iron flow through it. Professor West was even a member of a small crew of people who poured iron north of the arctic circle in Alaska. Laura's work has been exhibited internationally and focuses on the placement of cast figurative elements within installation and environmental formats. In the past several years, her work has expanded to include the use of digital technology and rapid prototyping. This research focuses on the use of digitally produced molds and patterns for use with cast metal.

    240 pounds of bronze

    #80 Crucible = 80 pounds of aluminum. For brass and bronze it is three times that amount.

    Seems like that would be 176 lbs of bronze.

      Oops, I have now read 2 different things. One says that crucibles are rated based on the number of pounds of Al they can hold so in that case a #80 crucible would hold about 240 lbs of bronze (3*80). The 176 lbs I posted earlier came from a different reference that stated that was referring to “A” shape crucibles which are rated by how many kg of brass they can hold. I’d place my bet on 240 lbs.

    I did a little googling and while I could not find a direct answer I think it’s about 240 pounds of bronze. Is that right? Wish I could have been at the pour today.

    According to “The Internet”, Crucibles are sized according to pound-weight-capacity of aluminum (i.e. a #80 crucible could hold 80 pounds of aluminum). Since bronze is roughly three times as dense as aluminum, a #80 crucible would hold approximately 240 pounds of bronze (which seems like an awful lot for the two guys in the picture to be handling. I guess casting metal is a pretty good workout).
