Just a quick history for the college student. The "light bulbs" you are looking at are vaccum tubes. And they are what came before transistors which were before ic chips. This is the stuff that started electronics, its history. Thats why some have suggested you take the time to discover what you have. For some its like restoring an old car.
As far a dangerous substances none really. Of course normal saftey concers apply. I see you use gloves, great, also avoid inhaleing dust etc. Mike.
