A penny stock typically trades outside of the major market exchanges at a relatively low price and has a small market capitalization.
CorianÂ® is dishwasher safe. CorianÂ® is non-porous so food and most household stains wipe off with a sponge and soapy water. Stubborn stains like coffee, grape juice, ink, hair dye and food coloring rub off with an abrasive household cleanser and a Scotch-Brite pad. Even tougher stains disappear using fine grade (180-200 grit) sandpaper.
However, that same lack of hardness makes Corian less durable than quartz. It can be burned by a hot pan, scratched by a knife, cracked by dropping something heavy on it, and stained by spills such as tomato sauce or red wine. It is somewhat germ-resistant, but not as much as quartz.
