Yes I love this. Its nice to see this thread. Kinda de railed a bit but on a good track. Ive delved in the metal casting world but only in aluminum because of the ease at the moment. Sand casting and lost foam. I have smelted down copper once into ingots but nothing more. I a small forge made out of a propane tank and some Kaowool. Reil Burner design. I have thought about fabricating a extruder/press mold to make crucibles quickly. Basically a sturdy plaster base with a hole in the bottom. Strong side walls and a inner piece to plunge and press the shape while the excess clay and be scraped away and also pushed out the bottom. Figured it would be a good idea in conjunction with a good clay mix that might not be as workable, but still have the good attributes to withstand abuse.
Plan to also build another furnace to get away from aluminum for a bit and expand my horizons in different metals. We have a ton of waste auto oil from doing my whole families oil changes at our shop so I want to utilize a waste oil burner soon as well.
