  2. Ladle (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/Ladle_(metallurgy)

    In metallurgy, a ladle is a bucket-shaped container or vessel used to transport and pour out molten metals. [1] Ladles are often used in foundries and range in size from small hand-carried vessels that resemble a kitchen ladle and hold 20 kilograms (44 lb) to large steelmill ladles that hold up to 300 tonnes (295 long tons; 331 short tons).

  3. Molybdomancy - Wikipedia

    en.wikipedia.org/wiki/Molybdomancy

    A molybdomancy kit includes a set of shaped lead ingots, to be melted over a candle flame in a spoon. A piece of molten lead after immersion in cold water. Molybdomancy (from Ancient Greek: μόλυβδος, romanized: molybdos, lit. 'lead' [1] and -mancy) is a technique of divination using molten metal.

  4. Gravity casting - Wikipedia

    en.wikipedia.org/wiki/Gravity_casting

    Gravity casting is among the oldest known processes for fabricating metals and metal alloys. [1] It involves the pouring of molten metal from a crucible into a mold under only the force of gravity, without the use of pressurized gases, vacuums, or centrifugal force.

  5. Crucible - Wikipedia

    en.wikipedia.org/wiki/Crucible

    These crucibles have added handles to allow for better manipulation, however, due to the poor preservation of the crucibles there is no evidence of a pouring spout. The main purpose of the crucible during this period was to keep the ore in the area where the heat was concentrated to separate it from impurities before shaping. [6]

  6. Metal casting - Wikipedia

    en.wikipedia.org/wiki/Metal_casting

    Sand casting requires a lead time of days, or even weeks sometimes, for production at high output rates (1–20 pieces/hr-mold) and is unsurpassed for large-part production. Green (moist) sand, which is black in color, has almost no part weight limit, whereas dry sand has a practical part mass limit of 2,300–2,700 kg (5,100–6,000 lb).

  7. Metallurgical assay - Wikipedia

    en.wikipedia.org/wiki/Metallurgical_assay

    Cupellation: the lead bullets are placed in porous crucibles (cupels) of bone ash or magnesium oxide and heated in air to about 1,000 °C. This is usually carried out in a 'muffle' furnace, containing a refractory muffle (usually nitride-bonded silicon carbide) heated externally by silicon carbide heating elements.

  8. Beaker (laboratory equipment) - Wikipedia

    en.wikipedia.org/wiki/Beaker_(laboratory_equipment)

    Most also have a small spout (or "beak") to aid pouring, as shown in the picture. Beakers are available in a wide range of sizes, from one milliliter up to several liters. A beaker is distinguished from a flask by having straight rather than sloping sides. [2] The exception to this definition is a slightly conical-sided beaker called a Philips ...

  9. Ludlow Typograph - Wikipedia

    en.wikipedia.org/wiki/Ludlow_Typograph

    The machine has a heated crucible for the hot type metal, with a mechanically actuated plunger which operates as part of the injection cycle. The pot on the machine was usually left on overnight during the week, with some flux added to the pot to reduce oxidation. At the end of each week, the plunger assembly had to be disassembled (while hot ...
