Celebrating it's 28th anniversary this year (2006), the famous Luminarc product we all love as the "Working Glass", was originally designed to be a jelly jar for preserves. That model would have had a pressure-lock lid like typical American canning jars. Trendy American consumers in those days were excited by finding unusual uses for everyday items... and soon discovered that this jelly jar really "Worked" for lots of things!

The large capacity was perfect for drinks with lots of ice! The tumbler's heavy weight made it possible to drink your coffee or tea in the same glass, too! The flexible lid we designed made it great for storing in the fridge or even the freezer...and for carrying those home-made lunch entrees and snacks to work or school. Toss in a votive candle, and it "Works" as a cool lighting element. A bunch of them make great egg-dying vats for little ones to enjoy as well. The uses are endless.

And, its thick, bulky design makes it nearly indestructible in normal use. Indeed, we're sure that many glasses are still "Working" for their owners after all these years!

Luminarc has discontinued the production of Working Glass products in colors.
