why this product

This wide enamelware coffee mug is unbreakable to see you through every last one of your drowsy morning coffees. Tough porcelain enamel can be heated right on the stove top or an open flame — even in the oven — so this is a great all-around heat-and-serve vessel, particularly if you’re keeping things very minimal in the kitchen.

Porcelain enamel won’t affect the flavor of what’s inside, and even the richest oils can be fully washed off the surface, so go ahead and drink coffee out of it in the morning, then sip tomato soup out of it at night.

The surface doesn’t harbor bacteria like a crack in ceramic, and doesn’t have any harmful chemicals to leech like BPA in plastic.

The company that makes these containers has been specializing in porcelain enamel for over 80 years, but started in 1550 (that’s 461 years ago, if you don’t have a calculator handy) as a pan-making firm. Despite being very old, the company strives to produce their enamelware with a minimum of energy waste. They have their own hydroelectric power stations, reuse generated heat three times over, and are working toward fuel oil-independence.

use & care

Porcelain enamel is the coating around a core of metal, so don't put this container in the microwave. If you've heated it on the stove, be sure to let it cool before submerging it in water-- a sudden change in temperature could cause the metal to warp. This is sturdy, but not invincible. Dropping porcelain enamelware onto a stone floor can cause chips in the enamel.

This mug is dishwasher safe, but is also easy to clean by hand. If there's food stuck on the bottom, soak it with a bit of hot water and dish soap.

The mug is safe for those with a nickel allergy.


production & design

Only natural, abundantly available raw materials are used for enameling this mug (namely: glass, a potassium compound and metal oxide).

To carry out the high-heat enameling of their products, the company constructed three of their own hydroelectric power stations that allow them to use 100% green electricity. This saves 4,600 tons of carbon dioxide and 3.6 tons of sulfur oxide and sulfur dioxide from ever being made and released into our air. The construction of their drying and burning facilities allows them to use and reuse the heat they generate for three different purposes. They're excited about residual heat and are working towards the day when they are completely independent from fuel oil.

The mug is the opposite of disposable-- you'll use it a thousand times over, but for good measure, it is 100% recyclable.
