Bronze pour documented start to finish, barely cut

The thing that jumped out at me first: almost 300 pounds of bronze going into just two investment molds, shown nearly uncut. The maker left the whole ten minutes intact apart from trimming three minutes of downtime while the metal came down to pouring temperature. Watching a pour at real speed, with all the small pauses and corrections left in, is rare, and it makes the scale of the work feel real in a way edited clips never do.



The sequence itself is worth studying. The furnace lid is opened with long leverage bars, the crucible is lifted out on an overhead chain hoist with a lifting clamp, then set into a two-man pouring shank ring and secured. One person skims dross and slag off the melt with a long rod before anything moves toward the molds. The crews talk each other through every lift and lower, which given the weight involved seems less like ceremony and more like the only sane way to run it. Both operators are in aluminized heat-reflective suits with face shields and heavy gloves.



These cast sections are the first two of six large hollow pieces with quarter-inch walls, all part of an abstract sculpture headed for a local hospital. Once all six are done the finished work should come in around 800 pounds. The wax side interested me too: brown stock is partly new and partly reclaimed, formed in plaster molds, with red wax added after cleanup. When everything burns out the red blends in and turns brown anyway.



The one open thread: the maker admits not being experienced enough to say whether new and reclaimed wax behave differently. That is a genuinely interesting question, and I hope a future pour answers it.

The cardboard dropped into the furnace before the crucible goes back in is the kind of small trick that separates working foundries from hobby setups. The burning layer leaves carbon on the floor so the crucible will not fuse to the furnace bottom. It costs nothing and saves a crucible. Clever, low-tech thinking like that is half the reason uncut footage like this is worth watching closely.

Does anyone know how the pouring height was handled here? The crucible looks like it sits well above the sprues in that sand-filled bed, and with nearly 300 pounds going in I would expect turbulence to be a real porosity risk. Also curious whether the quiet, velocity-and-pressure feeding approach mentioned by the maker changes how fast the molds fill compared to a more conventional pour.

If the maker does another run of the remaining sections, it might be worth splitting the next melt so one mold gets mostly virgin wax-derived metal and the other gets a higher reclaimed share, then comparing fill quality side by side. That would turn the open question about new versus reclaimed wax into actual evidence, and with four sections still to cast there is plenty of opportunity to test it without extra effort.
