New Glass cutting tool
Well actually I can not take credit, my wife was using ceramic knife
from Harbor Frieght to cut an apple. She was cutting on a small corel plate it broke, so if you have trouble cutting glass with the typical glass cutter. I got three knives for about $26 before tax. They are good knives. Mark |

Mark Many years ago I had placed one of those red clay flower pots on a Corelle dinner plate. I don't recall why, but at some point I decided to spin the pot on the plate, perhaps to look at a different side of the plant. One small turn, a screech was heard and the plate exploded. It sent ridiculously thin curved slivers flying about 3 feet in all directions. Ah, but it wasn't done yet. For the next 15 minutes or so, the part of the plate that remained kept making these little "clink" sounds as more skinny curved shards continued to break off of the edge of the plate and drop to the table. Obviously, I hit the resonant frequency of the plate which caused the initial explosion. The more amazing thing, at least to me, was the internal stresses that remained, causing continued, yet gentler *curved* damage. It was pretty freaky. |

I wonder if anyone will be mad if I attempt to sacrifice a dinner plate. Funny, I thought those Corelle plates were supposed to be near-indestructible. |

In the 45 years or so that I've been using Corelle I think I've managed to break half a dozen Corelle dishes. |

After many years, Corel gets very brittle and will shatter into a kabillion very small shards with only a small impact. It is tempered glass and acts like it. As you suspect, your flower pot probably scratched it, starting its disintegration. |

I bought one of the paring knives about 5 or 6 years ago and only recently was my wife able to nick the edge. She's terrible with knives and gets ****ed a me when I sharpen them. I try to explain but. . . Take a regular dinner place, "China" and the base ring is unglazed. Got a dull knife? Run a couple of passes at the right angle with each side of the blade and it's dull no more. |
