I was a chem major for a while, and did a lot of labs. I dropped some fairly expensive glassware on the tile lab floors, and discovered that they mostly did not break IF I caught them on the first bounce. If not, they would always shatter. I was a frequent visitor to Fisher Scientific to replace the pieces I missed. Standing waves? There must be some scientific explanation of this phenomenon. Anyone? Craig?

It is a traditional brown bottle, and can be corked for the vino or capped for the cider. The first time I dropped a bottle on the concrete floor of the processing room while moving bottles from the filler to the capping stand, I about had heart failure and envisioned glass everywhere. To my amazement, the bottle bounced, and I caught it on the rebound. There after, i just tried to catch the bottle on the rebound. When I ran out of the bottles, I found a deal on 8 pallets of green bottles made in meh-he-co. They could be corked or capped, so I bought them. They were VERY heavy! A case of empty bottles weighed almost as much as a case of filled W25 bottles! The first time one slipped out of my hand, i just prepared to catch it on the rebound. Not so. Glass shards everywhere! Every time I dropped a green one, it shattered. I guess the meh-he-co glass is not the same quality as the St Gobain glass made in the US of A or our northern neighbour! It was an eye-opening experience about the differences in glass. I have no idea why the W25 glass is so resilient. Perhaps there is an annealing or similar stress relieving process that the green ones did not get. The way the green glass flew, it was evident that it had a lot of internal stress. _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
