Kang prepared robot duplicates to replace the slain counterparts to rule the empires of every Kang in existence. At the same time, Kang re-took his 40th-century base via his Growing Man. After the rest of the counterparts were eliminated, the prime Kang slew the rest of the Council.
Stoneware is a rather broad term for pottery or other ceramics fired at a relatively high temperature. A modern technical definition is a vitreous or semi-vitreous ceramic made primarily from stoneware clay or non-refractory fire clay.
Where it gets more confusing is that many kitchen places are refering to some of the manufactured stones as quartz. They are made of I think it is 95% quartz that is crushed and mixed with an epoxy to produce slabs for counters, you can sometimes see air bubbles on the bottom of the samples they have in the showroom.
