Yes, but they are THIN (not the usual thickness of silicone products. They do work well on cupcakes, however.

They are silicone. They are also a bit stretchy, so don't be concerned if they appear to be a little small for your jar.

They must be plastic. They are marked "Not Oven Safe" They are marked "BPA Free". The do not appear to be as flexible as silicone and the center viewing window is a semi flexible clear plastic.

Hello! I checked the label and doesn't say anything about silicone. Good luck!

Yes, they are 100% silicone and they're easy to use, especially if you wipe the inside with a drop of cooking oil. The oil helps the egg slide out unbroken. I even take them on camping trips. Cleanup is a breeze compared to a greasy skillet.

The packaging does not say BPA free, but it does say that it is 100% FDA grade silicone.

Nope. They are fine after washing. I didn't notice any smell or taste from the silicone.

I've been wondering the same thing, but unfortunately I don't remember seeing it on the package either. I do believe that silicone is BPA free and I'm praying that I'm right!

They arent quite silicone, but softer than rubber. Its pretty much an even mix.

No these are silicone baking cups for a novel cupcake. I purchased to bake in for birthday celebrations.

I'm not sure. The description says: "100% FDA Approved Food Grade Silicone, BPA Free".

They are either silicon, or silicon-like. Whatever they are made of, they are incredibly pliable, do not dry out , and work extremely well.

No, silicone is a high temperature polymer. Nothing I have taken out of the oven, up to 450F has damaged the gloves.

No. On the sides there is a "grip" material which the description says is silicone.

Not sure if 100% silicone, but you can't see through them at all when bent. Completely opaque.

I am not completely sure, because these are made for ice, and not designed for baking. Yet, Wikipedia says of silicone in general that it has a thermal stability temperature range of −100 to 250 °C, and they are made of silicone. To be completely sure, you could contact the manufacturer.
