Query: Not the same Pyrex: shatters into sharp tiny pieces

So, my Pyrex measuring cup fell the distance of one foot onto my plain formica counter and pretty much exploded. There were sharp tiny shards everywhere -- even five feet away. It was almost impressive: I didn't know something could shatter so widely and effectively. I had to throw out the night's dinner, which was sitting on the stovetop nearby, and vacuum/mop the kitchen several times. I was still finding tiny slivers of glass days later. I don't take issue with the thing breaking: I dropped it, after all. But the way it broke makes it bad news in any kitchen.
