you know those old cartoons? i recall one where these records were being thrown and breaking like plates...
why would they do that? did they used to make records of something other than vinyl?

78's used to be made out of shellac. The one's I have would break more easily due to being more brittle & less flexible. Nothing to play them on anyway so it wouldn't really matter. A friend of mine once threw Pink Floyd's Meddle LP out of a three story building in a fit of rage, it landed on concrete & didn't break. It didn't sound too good after that though.

Records wouldn't break until when using brute strength against a hard surface and thrown at the right angle like a ninja star weapon (well, like frisbee style). You don't believe me, see THE EXORCIST where many 7" records are flying thru the air to the window area at one stage. Oh, don't worry, this has nothing to do with devilish curse!   |

i still don't understand why they don't make them of ceramic or kevlar or vectarin or something hugely abrasion resistant and less toxic than vinyl.

The diamond stylus would wear out very quickly if they did that!  |

You can place a record over an upside down ceramic bowl, put it in the oven for a couple of minutes at 100 degrees C and then you have an analog way to serve popcorn or potato chips (crisps for UK and Australian readers......)
Vinyl actually has very desirable properties for the recording industry. It wears out, creating demand for replacements, dust particles are rammed into the groove by the stylus creating sandpaper to wear out the stylus, creating a need for replacements. The geometric challenges of playing a record back properly created opportunities for all sorts of contraptions to improve tracking angle error, azimuth and resonance of the disc. Along came the CD industry and moved tweakability into the electronics requiring ENGINEERS. That was the original sin - taking away a bunch of snake oil from the industry.
I was fed a rumor years ago that the plasticizer in vinyl (keeps it soft and supple) would evaporate after a while leaving the disks brittle. I have no evidence of this in my collection
