Help me identify this glassware! I'm a freshly graduated physics and math teacher moved into a small school from the late 1920s.  The equipment here is old and confusing, at the very least.  I have found many things which I have never seen before.  I would like some help identifying what I have and what I can do with them, if anything.

1. A load of copper pots.  For boiling something perhaps?


2. Some sort of wash bottle?  Why is the cork on there?


3. I managed to make out "unitized wash bottle" on the back.  This serves the same function as the last one, I presume.


4. It reminds me of a graduated cylinder until the frosted top and the "arms" that poke out the sides.  What is this for?


5. This reminds me of halogen bulbs.  Again, I have no idea what this is for.


6. I've taken to calling this "trumpet" glass pipe.  What is it used for?


7. This large bulb has confused me since day one.  I feel like it needs some sort of current passed through the ends.  It reminds me of a cathode ray tube in a way.  I'm completely lost on this one.


8. Here.  Have a free safety poster!  Not as good as old Carol, though.
#4 is a collection vessel of some sort. 

The ground glass fitting would have connected to some other ground glass fitting. A set of the ears would be on the connecting piece of glassware also. Then springs would hold the two pieces together.
