ADVANTAGES:
1. It is a good conductor of heat.
2. It has low specific hest capacity.
3. It has uniform expansion.
4. It is opaque n shining.
5. It does not stick to glass-sides.
6. It has a high b.p. of 357 degree C.
7. It is easily available in pure state.
8. It exerts low vapour pressure.
DISADVANTAGES:
1. Its expansion for 1 degree C rise in temp. is not very large n hence small changes in the temp. cannot be accurately measured.
2. It freezes below -39 degree C n cannot be used in very cold regions like Antarctic or the Arctic.

Well there's the fact that it's POISONOUS!!!
You don't want to put it into a fire because the mercury will vaporize and then will build up pressure in the tube eventually shattering it, putting POISONOUS Mercury EVERYWHERE!

The stuff inside can kill you. Be very careful not to break it.

THEY ONLY WORK WITHIN A SPECIFIC TEMPERATURE RANGE, THEY ARE TRADOTIONALLY MADE OF GLASS, (FRAGILE) AND THEY CONTAIN POISONOUS LIQUID METAL.
