  2. Lithuanian long currency - Wikipedia

    en.wikipedia.org/wiki/Lithuanian_long_currency

    The wax would melt leaving a mold for the ingot. Molten silver was poured into the mold using a special clay scoop. After cooling off, the mold was broken to remove the ingot. [16] Therefore, most molds were one-time use though a few examples of ingots are known that were cast using the same mold. Because of this technique, archaeologists have ...

  3. Ingot - Wikipedia

    en.wikipedia.org/wiki/Ingot

    For a top-poured ingot, as the liquid cools within the mold, differential volume effects cause the top of the liquid to recede leaving a curved surface at the mold top which may eventually be required to be machined from the ingot. The mold cooling effect creates an advancing solidification front, which has several associated zones, closer to ...

  4. Oxhide ingot - Wikipedia

    en.wikipedia.org/wiki/Oxhide_ingot

    This is not to say that oxhide ingots were normally cast in limestone molds. Using an experimental clay mold, Bass et al. argue that the ingot's smooth side was in contact with the mold while its rough side was exposed to the atmosphere. [6]: 70 The roughness results from the interaction of the atmosphere and the cooling metal. [6]: 70

  5. Metal casting - Wikipedia

    en.wikipedia.org/wiki/Metal_casting

    Mold cavity: The combined open area of the molding material and core, where the metal is poured to produce the casting. Riser: An extra void in the mold that fills with molten material to compensate for shrinkage during solidification. Gating system: The network of connected channels that deliver the molten material to the mold cavities.

  6. Yemenite silversmithing - Wikipedia

    en.wikipedia.org/wiki/Yemenite_silversmithing

    Silver wires were made in Yemen by taking raw, unshaped silver (sabāyik in Arabic), [18] melting it in a crucible and then pouring the melted silver into a finger-length mold made from special earth shaped like a tube. [19] This produced ingots.

  7. Coin counterfeiting - Wikipedia

    en.wikipedia.org/wiki/Coin_counterfeiting

    The coin mold would come with two halves that would be lined with clay to make an impression of a genuine coin, then molten lead would be poured into the mold and the fake coin later plated with a thin layer of silver. Legitimate U.S. coins were made by government mints and stamped from silver or gold coin discs as most counterfeit coins were ...

  8. Cast coinage - Wikipedia

    en.wikipedia.org/wiki/Cast_coinage

    Cast coinage refers to coins made by pouring melted metal into a mold, i.e. casting. It has been used for regular coins, particularly in East Asia, but also other areas on a smaller scale (e.g. the ancient Mediterranean world). The method differs from the current mode of coin production, which is done by striking coin blanks that have been cut ...

  9. Kuki Silver Mine - Wikipedia

    en.wikipedia.org/wiki/Kuki_Silver_Mine

    The production volume was about 210.5 tons (1.9 tons of silver) in 1903 and about 255.4 tons (2.2 tons of silver) in 1904. The ingots were transported via Hamada Port to Osaka. However, in 1907, the entrance of the tunnel was submerged, and the amount of silver produced decreased sharply.
