    The muffin man is seated at the table
    In the laboratory of the metal muffin Research kitchen.
    Reaching for an oversized chrome spoon,
    He gathers an intimate quantity of soda can
    Remnants and brushing his scapular aside,
    Proceeds to dump these inside of his shirt...
    He turns to us and speaks:
    "Some people like metal cupcakes better.
    I for one care less for them!"
    Arrogantly twisting the sterile canvas
    Snoot of a fully charged icing anointment utensil,
    He poots forth a quarter-ounce green rosette,
    - oh ah yuk, yuk... let's try that again...!
    He poots forth a quarter-ounce green rosette
    Near the summit of a dense,
    But radiant aluminium muffin of his own design.
    Later he says:
    "Some people... some people like metal cupcakes
    Exclusively, while myself, I say,
    There is naught nor ought there be nothing
    So exalted on the face of God's grey
    Earth as that prince of foods... the metal muffin!"
    "The universe is under no obligation to make sense to you."

    I did this stuff (smelting aluminum and pouring into sand molds to make fireplace tools) in my grade 9 metal shop class in junior high school......we were grouped in pairs and there was a lot of fooling around going on as kids do and I watched as molten aluminum got spilled and got poured over some poor kids foot! ........hot is right! 3rd degree burns to his foot when it burnt through his shoe!......made me appreciate and kind of fear heat and fire from that point on! :shock:
    Why,driving into a brick wall at 60 miles per hour, would I expect it not to hurt!

    I have worked in several places that had foundries. The molds were computer machined, but the rest is old basic stuff as shown in the video. One of the problems with non ornamental applications is porosity, or trapped gas bubbles. One of my jobs was to verify the computer x-ray sorting machine did not screw up. It often did.

    Janet will get that.
    All the world’s a stage, but obviously the play is unrehearsed and everybody is ad-libbing his lines. Maybe that’s why it’s hard to tell if we’re living in a tragedy or a farce.

    I had a temporary job once, making small castings destined for ACDelco. After casting, I took them to be plated, then to be "proofed" which seemed to be boiling them in a mixture of borax and some waxy substance. Apparently this was to fill any porosity in the castings but the process was kept "secret".

    I used to call on a foundry in Iowa where they made huge aluminum alloy castings, like the cases for big helicopter engines. This was supposed to be the only place that could make something that big as a single piece. I was always fascinated by the combination of ultra-modern and ultra-ancient technology.
