Just when I’m thinking about how to display all of mine. Do I have to put a hazmat sign on the display case now? Bad enough things like Christmas lights have lead warnings on them these days.

That article implies touching the outside of the glass is the issue. In any case, I kept mine in a dark cabinet out of reach, yet my dad would use my ESB glasses for whatever that spicy egg nog like concoction he liked to have on a weekend for a few years. Boy, was I pissed about that at the time. Interesting thing is they survived untold trips inside the dishwasher that faded other things like Muppet glasses. The paint on the Star Wars and ESB glasses always seemed more durable than the Jedi set.

What of all those plastic tumblers I drank out of as a kid? And holy hell, are my 2009 Star Trek glasses even safe?

After all these years, I can’t recall for sure if BK sold you the SW glasses with soda in it or not.

I have to wonder about all the Sigma Star Wars ceramics now. Besides the infamous Threepio tape dispenser, they made mugs and even a Luke Taun Taun teapot.

None of those really struck me as really being suitable for having a cup of tea.

All my Sigma mugs perished in the 1994 Northridge Earthquake. My Rumph Star Wars mugs survived without a scratch. My Rumph Chewie survived a Laserdisc player landing on him, the player was totalled though.
