-
Steel glass
-
Copper glass
-
Brass glass
-
Plastic glass
Technically, however, glass can refer either to the material or to a drinking vessel.
A tumbler generally refers to a drinking vessel without a stem, usually with a relatively flat base. Tumblers are available in many shapes, capacities and materials.
They are commonly used for:
-
Drinking water
-
Juice
-
Milk
-
Buttermilk or chaas
-
Lassi
-
Soft drinks
-
Other compatible beverages
Common materials include:
-
Stainless steel
-
Glass
-
Copper
-
Brass
-
Plastic
-
Ceramic
-
Double-wall or insulated constructions
The best tumbler depends on the beverage, intended use, material, durability, ease of cleaning and temperature requirements.

Is not normally intended for leak-proof transport
Unlike stemware, a tumbler:
-
Has no stem
-
Rests directly on its base
Tumblers range from simple everyday vessels to:
-
Decorative tableware
-
Insulated drinkware
-
Traditional metal drinking vessels
-
Specialized beverage glasses
The exact terminology varies by region and manufacturer.

Safety Information
Use Food-Contact-Suitable Materials
A tumbler directly contacts beverages.
The:
-
Interior
-
Rim
-
Coating
-
Lining
-
Decorative food-contact surfaces
should be appropriate for their intended use.
FDA regulates substances that contact food through containers, packaging and related applications, while FSSAI establishes applicable requirements for food-contact materials in India. (U.S. Food and Drug Administration)
Check for Chips and Cracks
Do not continue using glass or ceramic tumblers with:
-
Chipped drinking rims
-
Significant cracks
-
Structural damage
These can cause:
-
Cuts
-
Breakage during use
Be Careful With Hot Beverages
Single-wall metal can become very hot externally.
Ordinary glass may be vulnerable to thermal shock.
Use hot beverages only when the tumbler is designed for them.
Avoid Thermal Shock
Thermal shock occurs when rapid temperature change creates stress in a material.
For example, avoid:
-
Pouring boiling liquid into an unverified cold glass
-
Moving hot glassware directly onto very cold or wet surfaces
Use only according to the manufacturer’s temperature guidance.
Be Careful With Copper and Brass
Copper and copper-containing alloys can react with certain acidic foods and beverages.
Avoid prolonged storage of acidic liquids in unlined reactive metal vessels unless the product is specifically designed for that use.
Be Careful With Decorative Ceramicware
Decorative pottery should not automatically be assumed to be safe drinkware.
FDA warns that some improperly manufactured traditional pottery can release lead into food or drinks and advises that decorative items not intended for food use should not be used as foodware. (U.S. Food and Drug Administration)
Do Not Microwave Metal Tumblers
Do not place:
-
Stainless steel
-
Copper
-
Brass
-
Aluminium
tumblers in a conventional microwave oven.
