I have bought three silicone spatulas so far and all of them start "melting" when used to flip frying eggs.
I don't leave them in the pan or anything and, supposedly, silicone should be able to withstand much higher temperatures than frying oil.
But I've had the same happen with a "silicone basket"-like utensil (I don't know exactly what it was called) which, quite literally, melted and fell apart when I used it for the first time to fish french fries out of the frier.
I also see a lot of people having the same experience over the wire/internet.
Why is this happening and is there a way to confirm the utensils are real silicone and not something else?
After some digging I have discovered I have, in fact, bought a nylon spatula, instead of a silicone one.
I am going to copy @unlisted's comment for benefit of future readers:
Though both obviously 'plasticky' nylon is hard & silicone is soft. If it will squish a bit, it's silicone. Nylon will bend but you could never describe it as 'squishy'. Of course, even if it passes that test it may still not be food-grade.
