xr4x4,
"caulk is caulk" and "silicone is silicone" ... so what, who said that they were'nt? In the UK, the London based OP used the term "caulk" to mean a sealant, and a method of sealing the frame and tile - go figure?
"They are different" - read what i wrote.
"used for different things" - read what i wrote.
Why cant you grasp that reading what's been written might solve some of your foolish bewilderment.

Are you thick ? Cant you read what i've written? Or are you some kind of child who merely repeats what other informants write?

Johnmelad,
"caulk and silicone" often mean different things but they are also inter-changeable terms, eg. the OP's reference to caulk as a sealant and a method of sealing.
If you took the trouble to look up some of my past posts you might be surprised to discover that i have a grasp of where the Forum is located, and a little knowledge of UK building practices & terms.
When you try to be smart you should be aware that in both the UK & the USA, sinks are in kitchens, and basins in bathrooms. In the USA, basins are never referred to as sinks by professional people.
It might also surprise you to learn that the term "skirting" is still used by some traditional US joinery shops.
FWIW: i could post pics of cartridge tubes of UK silicone caulk but why dont you go google them for your own education?
