Oozing Goo - The Lava Lamp Syndicate

Hi, I recently added a green Century to my collection and I've noticed it has more light pinholes in the Starlite base than my other two. I've been told the red lamp is from the 60s (though I'm not sure) and I know the blue was made in 1990, but I'm really curious about the green lamp. Can anyone help me identify the year the green lamp was made (and the red one as well if possible.) I'd really appreciate any insight. Thanks!

Nice lamps!  I can't speak to when the green was made based on number of light holes but others can.  There may be a couple of ways to determine when made though.  One is to take the globe and turn upside down, look to see if there is a date imprint in the bottom of the globe.  Sometimes it's there, sometimes not.  Another way is to look through the glass into the cap area.  There should be identification labels there if the globe has not ever been opened.  This should have a date on one of the labels (sometimes there is only a single label).  Here is an example of a cap that has been removed that has the labels still attached.  (not my pic)

Cool info. I like the idea of determining the years of production and the discovery perhaps of the differing pin hole number in the starlight bases.

Thanks Keith. That really is great info. I had no idea. I'll give the bottom of the globe a shot after my lamps cool down. If I don't see a date there maybe, if I'm feeling confident enough, I'll try to remove the caps without cracking them. I appreciate it.

You should be able to see the labels without removing the caps by tilting the globe and looking through the glass.  If you do remove the caps DON'T use tools or you could crack the cap.

It's interesting, I would've never thought about the amount of pinholes but when I got the green one and I started looking around, there weren't any others quite like it. I haven't had any luck finding any reference to pinhole numbers anywhere online. It'll be interesting to see if anyone else has some insight.

Ah, okay. I'll definitely look tomorrow then. Thanks again!

I found some information you will be interested in, especially Jonas Clark-Elliott's comment.  A good chance the green is from the early 70's.  (I wanted to say that anyway but was unsure.  This particular post kept rattling around in my head so I had to find it, lol)

Pretty interesting. The seller of the green one told me he had it for "thirty, probably forty years" so that would make sense that it's an early 70's model. 

I did a quick measurement on all three, and it looks like the base on the green lamp and the base on the blue come in at just over seven inches, while the red is just a hair under seven. So now I need to cross check all of that, though I think that means the red was made in the 70's (having problems seeing what's under the cap.)
