Product Description

Glass rock slag is a glassy, colorful, industrial byproduct created from smelting ore (often iron) or from manufacturing glass, often found as waste, landscaping rock, or "cullet". It is frequently mistaken for natural obsidian due to its glassy texture, conchoidal fracture, and vibrant colors like blue, green, and purple.

What is the typical lead time for an order?
Delivery usually takes 7-10 days depending on the order volume and destination. We have a production capacity of 2 containers per day.
