How tall is this building?

Dianna,

I'm trying to better understand gravitational time dilation (GTD) and I could use some help.  I can only find subatomic test results, e. g. radioactive decay/muons, but I can not find test results at a higher level, by measure of testing the behavior of chemical elements.  For example,  let there be an atomic clock measuring time, down to the nanosecond, paired along with a closed system aquarium growing a crystal from a mass of chemical gas measured to exact atomic weight, down to the atom.  Employing your "space-scraper" as an imaginary model to test a speculative hypothesis, if two similar aquariums and atomic clocks where placed in the building, one pair set in place at the top floor, and the other set at the bottom, when comparing the weights of the two grown crystals, after many years, between the two aquariums, would the top crystal weight more, be heavier in mass?  I assume the top crystal would weigh more if the time dilation effect observed in the atomic clock is demonstrative of physical/chemical properties.  I would be interested to see test results from non-subatomic clock experiments, as well as electrical tests, to affirm time dilation.  Are there are any such alternative tests to read about the GTD subject?

My imagination is "seeing" a possible issue, but I don't know how to communicate it, other than with a not so great pseudo "science" experiment based upon a silly example:  let there be a room with two clocks measuring time, one clock with a "pendulum" based from liquid water, and the other clock using a mechanical spring as its "pendulum."  When the room temperature is lowered below freezing the water clock slows to a stop, and when the temperature is heated above boiling, the water clock dramatically speeds up, all the while the clock with a mechanical spring ticks along at, more or less, a consistent rate of speed.  In other words, I wonder if the concentration of gravity alters atomic decay in an observable manner, but does this gravitational effect also equally change the rate of chemical reactions and vapor kinetics for non-radioactive elements, or electricity?
