Why does a ceramic bowl keep oatmeal hot longer than a stainless steel bowl?
Metals including stainless steel are excellent conductors of heat. The heat in the oatmeal will be absorbed by the metal bowl and then lost to anything cooler it's in contact with, such as the table top, and the surrounding atmosphere, much faster than would happen with a ceramic bowl. That is why "heat sinks" used in electronics, notably computers, are made of metal.
What is more porous A. a bowl filled with cherries B. a bowl filled with blueberries C. a bowl filled with apples D. a bowl filled with grapes?
C. A bowl filled with apples is the more porous of the four. Porosity is a function of the size of the fruit. The larger the fruit, the more porous the bowl will be (the more air or water that can be placed in the bowl). The smaller the fruit, the less porous the bowl will be. Compare with a bowl of stones and a bowl of sand. The stones are more porous because the sand can be more densely compacted, leaving very little room for water.

How is quartz made?
Quartz singing bowls are made from a complex process where sand is melted and dropped into a centrifugal mold that fuses the particles into a sheet of crystal. This crystal is then fashioned into a bowl shape in the manufacturing process.
