Artland Iris Martini glass in ruby red. These glasses are known for their handcrafted, seeded glass design and vibrant color. Key features include: Design: The glass has a classic martini shape with a V-shaped bowl, a clear stem, and a round base. The ruby red color is achieved by adding gold salts to the molten glass, a technique used to create cranberry glass. The "seeded" texture refers to the tiny bubbles trapped within the glass, a characteristic of the Iris line. Material: It is made of durable, high-quality glass, resistant to chipping and breakage. Dimensions: Martini glasses typically hold between 8 and 10 ounces, but the Artland Iris martini glass can hold more. Care: They are dishwasher safe. Other Considerations: The martini glass shape is designed to prevent ingredients from separating and to keep the drink cold.
