In a similar vein, I would certainly challange Margaret
to also produce a block of both "granite" and "diorite"
by the geopolymer process. I would be satisfied with
a block about a foot square which should not tax a
person's budget as a 2.5 ton block would. In addition,
it would be instructive for her to make a piece of each
rock that is 2.5 cm by 1 cm so petrographic thin
sections can be made of them.
It is instructive that so far Margret can "talk the talk"
of speculating how geopolymers can be used to make
"limestone" blocks and granite and diorite artifacts
but fail miserably at "walking the walk" when it comes
to making even scale-down versions of these.
I find it difficult to accept that the geopolymer process
can duplicate in every detail the crystal structures that
form by the slow cooling of magma over hundreds of
thousands, even millions of years. There is simply no
way that a person can grow interlocking crystals of
quartz, felsspar, and other igneous minerals using
relatively "cold" geopolymers.
