Chemistry mythbusting

I have been told by several independent sources that if you microwave your molecular sieves for too long then you are left with a molecular sieve block. Molecular sieve blocks sound fun, so we decided to test it out.

We took average 4 A sieves in a round bottom and microwaved the shit out of them for about 4 minutes until they smelled weird. We managed to get them white hot, but no luck with fusing the little buggers together. I believe a higher wattage is required, but that doesn't explain all the reports about the sieves unexpectedly melting. I think we need to investigate different pore sizes.
