Large Glass Slag Boulder

This item appears to be a large, irregularly shaped mass of industrial glass slag, commonly referred to as 'cullet glass.' The specimen exhibits a predominant greenish-blue or seafoam hue with varying levels of opacity. Its physical characteristics include a heavily pitted and vesicular surface texture, which is indicative of gas bubbles trapped during the cooling process of molten glass. The exterior surface shows an uneven, organic topography with matte patches and glassy, translucent sections. The material is likely a byproduct of glass manufacturing or architectural glass production, possibly dating from the mid-20th century. There are no discernible maker's marks or signatures, as these are typically waste products rather than finished artisan pieces. The item shows signs of weathering and surface abrasions consistent with being an outdoor decorative element or garden ornament. The craftsmanship is unintentional, resulting from the random flow of molten waste, yet it possesses a distinct aesthetic appeal due to its sculptural form and light-refracting properties. Its size suggests it is a significant, heavy mass, fitting for a collection of geological or industrial curiosities.
