Material selection directly impacts durability, heat resistance, and aesthetic appeal. For high-end hospitality, crystal or thick-walled glass is preferred for its weight and clarity. For outdoor or industrial use, 304 stainless steel is the industry standard due to its corrosion resistance and fireproof properties. If sourcing for eco-friendly brands, ceramic or cement ashtrays offer a sustainable, heat-stable alternative. Always ensure the material has a high melting point and a non-porous surface to prevent odor absorption.
