When selecting glass display stands, the type of glass is the most critical factor for safety and clarity. You should prioritize Tempered Glass (Toughened Glass), which is 4-5 times stronger than standard glass and shatters into small, blunt pieces if broken. For high-end luxury items, consider Extra-Clear (Low-Iron) Glass to eliminate the green tint found in standard glass, ensuring maximum color accuracy for the displayed products. Ensure the glass thickness is at least 6mm to 8mm for shelves to support weight without bowing.
