Are Glass Coffee Mugs Safe?

Most people who enjoy a hot cup of coffee each morning do so from a ceramic mug, or maybe even an insulated travel mug for taking coffee on the go. But glass coffee mugs are an attractive alternative; they come in different shapes and sizes, and give a unique look to your morning coffee cup.

But are glass coffee mugs safe?

The Safety of Glass

Glass is an extremely safe material, and most glass mugs are lead free, so there should be no health concerns regarding their use. However, it is important to select a glass mug that is labeled as safe for hot fluids, or labeled as thermal or borosilicate. Some glass mugs on the market are not made to be microwaved or put in the dishwasher.

Glass Breakage

Glass is breakable, but glass mugs come in many different styles, sizes and thicknesses, so it is important to choose one that fits your needs. For people who are clumsy, or who have kids, thicker walled mugs or mugs with handles are a good choice. Handleless, tall and thin mugs can break more easily.

It is important to remember to allow the mug to slowly cool down with the beverage, before setting it down in a sink or washing it. A sudden temperature change from hot to cold can cause the glass to break or crack.

Care & Maintenance of Your Glass Mug

To keep your glass mug usable for a long time, there are some basic care and maintenance steps you should follow:

  • Check for chips – inspect the mug for chips or cracks before each use
  • Hand wash only – glass is delicate, so hand washing is recommended
  • Wash and dry – wash and dry the mug immediately after each use
  • Avoid microwaving – never microwave a glass mug or put it in the dishwasher
  • Store carefully – store glass mugs carefully, separately from other items like metal utensils

The Bottom Line

Glass is a safe material to drink from, but it is important to select an appropriate mug that is safe for hot beverages, and to handle it with care when using it and cleaning it. Taking these few steps will help you to enjoy your morning coffee in a beautiful glass mug for many years.
