OTOH, I know a bunch of folks who have tried using ivory coloured Corian
as fake ivory and gave up because it's too brittle in use.

Just bear in mind what it was designed for. As long as you aren't making a
"diving board" out of it you usually do OK. It is a surface material and
should
have a good substrate.

If you are going to use Corian you do not want a solid substrate. A solid
underlayment will work as an insulating layer. Corian does not transfer heat
well across its surface so if a hot item, ie coffee cup, pot etc is placed
on the surface Corian tries to transfer the heat through, if you have a
solid wood surface under Corian the heat is trapped. If you are using and
solid surface you want to build a substrate that resembles a ladder leaving
large open areas for heat to escape. And only bond wood to corian using
silicone to allow for differences in expansion and contraction.
