A few years ago I had had a great day chasing free flight model planes at Old Warden and was pretty tired... To rive me a bit for the drive home I reached for my flask of hot coffee....-and it slipped from my oily grasp and there was a tinkling sound as the coffee ran out of the broken glass liner. :( From that day on I've used stainless steel flasks. But, I have a luking suspicion that they tend to lose their effectiveness after a year or so. They don't seem to keep things as hot as they did when new. Could it be that the vacuum is gradually lost over a period of time? I'm thinking of trying a traditional glass flask again. What has been your experience with stainless flasks?
