1 oz Hand Poured Elemental Bullion Bars - 99.9% Pure Metal Ingots of Zinc, Bismuth, Tin, Lead - Metal Collection for Science, Display or Desk Decor Made in USA (4 Pack)

This 4-piece set includes four 1 oz metal bars made from 99.9% pure zinc, bismuth, tin, and lead. Each ingot is hand poured in the United States and finished with a smooth, polished surface for a clean, display-ready appearance. These compact metal bars are designed as collectible samples, offering a simple way to experience real elemental metals in a small and manageable size. Each piece is clearly marked for identification, with zinc, tin, and lead stamped and bismuth laser engraved due to its more brittle structure. Each metal offers its own unique characteristics. Bismuth is known for its ability to form colorful crystals, tin is valued for its low melting point, zinc is commonly used in alloys and coatings, and lead is recognized for its high density. This variety makes the set useful for learning, comparison, and display. Ideal for collectors, educators, and hobbyists, these 1 oz bars are well suited for element collections, desk display, and hands-on STEM learning. Their compact size makes them easy to store, handle, and showcase.
