Thank you to RMB for posting this.   I have indeed noticed that  my Corelle 
plates, when they fall on my tiled floor, do not just  break, but shatter in a 
million pieces and scatter all over the kitchen.   I.e., they explode.   
Fascinating.  What I want to know though,  is not whether you can kasher Corelle, 
but something different:  do you  have to tovel Corelle?  
 
Every year or so I go off and buy a few new bowls and plates  to replace the 
ones that have exploded in the course of the year, and then  I don't let 
anyone use the new ones until I get around to tovelling them, which,  depending on 
how many Avodahs there are in my inbox to read and respond to, can  take a 
while.  My husband says that Corelle does not need tevillah but  I think they are 
at least safek glass and therefore insist on tovelling  them, usually along 
with a few metal things (to replace the odd spoon and  fork that accidentally 
got thrown in the garbage in the course of the year) in  order to obviate any 
shailah of whether safek glass needs a bracha when  tovelling.  Shattered 
plates and discarded silverware tell you more  than you probably wanted to know 
about my housekeeping skills, but at least I am  conscientious about halacha -- 
or try to be.  Truthfully, even if you tell  me that my husband is right, I 
will probably continue to tovel Corelle, but I am  curious what the olam thinks.
