The other day I was cleaning a big box of 2 minute wax cylinders and wondered why some have solid inside core wax and some were ribbed. when did they change? I take it the solid was the first ones and then they went to ribs.
Also I noticed that most of the Edison's are pretty clean with only a few being attacked by mold yet the 3 Columbias are terrible. It must be some organic material in the columbias that make them more susceptible to mold attack.
Do you find the wax columbias are in worse shape when found in the wild?

I rarely find clean Columbia's in the wild. I found about 20 MINT cylinder cases w/cylinders that look unplayed but were badly molded - so sad. I wonder if it isn't the wax but possibly the cotton batting used in the Columbia record cases? They seem to be much more densely packed - maybe they also absorb more H2O and grow better mold?

These had been stored in a Herzog barrel cabinet with pegs all there life most likely. So in this case the cotton would not force them to spoil more than the Edison. it must be in the recipe for the wax.

Moo,
I believe it was sometime in 1906 that Edison first made the smooth inside core on his 2 minute cylinders. It apparently didn't last long before they reverted back to the ribs.

Oh so they had ribbed then smooth then back to ribbed. I wonder who talked Edison into that? The ribbed seem to be the better choice when putting the on a mandrel. Plus as tight as TAE was I would think the solid has more materials in them...

Hi Guys.
According to Frow (as opposed to Hoyle), this was a result of patent litigation. When North American Phonograph Company went bankrupt in 1894, there were several angry people. Many of the other changes at this time like copper diaphragms and the move to the end-gateless models were as a result of this. In the instance of the cylinder ribbing, they reverted when the patent ran out. There's a pretty thorough discussion on page 407 in the "Edison Cylinder Phonograph Companion". I've got a few of these myself which always had me wondering why they had the ribbing in the first place.

One possibility is that using the ribbing saves wax- a small amount but over the course of hundreds of cylinders it adds up. Martin
