Are they made of glass rather than plastic?

yes glass and very sturdy, dishwasher safe and microwave. They are absolutely wonderful!

They are glass, but not just silicon but 'borosilicate', which means they're like the same glass used for pyrex these days. This increases durability and the ability to handle thermal shock.

Yes, double walled glass, no plastic plug in the bottom. A little heavy but very good otherwise.

I doubt they are plastic. Pretty thick and dont break when dropped on a tile floor.

They are made of a type of plastic. They are very robust as I am using 6 pieces and have had no problems with them.

They are made with plastic, not glass. I just began using them over the weekend, and they appear very durable. I am really glad I purchased this product because I like to get all my ingredients set up before I start cooking, and these little beakers will enable me to pre-measure out flavorings and extracts.

Dear Math, thanks for asking. These items are made of glass (apart from the absinthe spoons of course!)

They look like they could be plastic glasses, but they aren't. The set we have is all glass. They are very nice glasses and they have no issues in the dishwasher.

No they are plastic. They work really well! Pay attention to how the old ones are threaded and just do the same.

The glasses I got (both large and small) are all glass, no plastic. I know that Fiesta makes plastic glasses but these are not plastic.

They are made of plastic. I wouldn't say it is cheap. I think they are worth the price.

I'm not positive but think they are made of plastic. I'm sure they are not Styrofoam.

I believe they are plastic but I am not entirely sure as I bought this as a gift for my daughter last Christmas.

Yes! They're made of plastic, but seem very sturdy. They're also easy to clean.
