93% Natural? It is mostly plastic and resin. Resin pooling happens and typically is allowed and not something they replace tops over from what I know.

Resin pooling is a known issues with many quartz colors/brands and not considered a defect. You can do a search in Houzz Discussions to read older threads on the same topic.

You will also get this in natural stones that have some fissures that need to be filled. Here is a "spot" on my Taj Mahal Quartzite (natural stone).

Yes, resin pooling. The Quartz warranty will not cover replacement due to resin pooling, especially for small ones like you show.

I've decided to do nothing with the spots. I find it curious that in my previous home, of the four Cambria Torquay slabs installed, none featured these pools. I was hoping to hear from other Torquay owners to see if they experienced the same. Cambria stated they will drill the spots if later I change my mind.

It just happens, since it is man mad and they pour the resin, it is not controllable, some slabs you may get them and others might not.
