Cast Iron Dust, High Carbon, Mesh 150
A high carbon cast iron powder suitable for sintering, melting, fireworks, and hand warmers. May also be used as a filler in resins or added to concrete for a rust effect. Includes some clumps naturally formed due to stacking pressure, which can be removed by re-screening, chopping, or grinding. Suitable for wood stains when mixed with vinegar, with clumps gradually disintegrating. Particles are slightly hydrofoabic to reduce fire risks; surfactant recommended for increased wetting properties in specific applications.

Laboratory Support Stand with Triangular Cast Iron Base and Steel Rod
This assembly consists of a triangular cast iron base and a vertical plated steel rod, designed to function as a general-purpose laboratory support stand. The base is fabricated from high-mass cast iron to ensure a low center of gravity and high resistance to mechanical tipping. Its three-point geometry provides stable contact with the bench surface, compensating for minor surface irregularities and enhancing overall stability.
The base features a central threaded bore, machined to accept a 13 mm (1/2 in.) diameter rod with standard threading. The rod is composed of plated carbon steel, offering moderate corrosion resistance and sufficient rigidity under typical lab loading conditions. It has a total length of 500 mm (20 in.), suitable for vertical mounting of various laboratory fixtures such as clamps, rings, and holders.
To resist degradation in chemically active environments, the base is coated with a chemical-resistant enamel paint, which provides a protective barrier against spills and vapors encountered in routine laboratory operations.
