50 years ago I bought a carousel pipe rack with an ashtray on top. (The image of one below is from the web, but mine is identical.) It served me well for all these years and then recently the ashtray broke in half right down the center. I have no idea why. I looked on line for a replacement but didn't like what people were asking for them. So, for a few months I lived without the ashtray and used another one on the end table next to my desk... works, but not as convenient. Then a while back I drove past a garage sale and stopped to take a look. To my amazement there it was, an identical, unused ashtray at a give-a-way price. I jumped on it and was back in business happy as a duck at my good luck. Then the curse struck! This time I was at my computer having a pipe and I heard a sharp "crack". You guessed it, the new ashtray had done exactly what the other one had. Cleaved itself in half as clean as a whistle. And no, there was not any burning ashes in it at the time. Now I"m on the lookout for another replacement.... this time I thinking stainless steel.
