  1. "Most ceramics resist the flow of electric current, and for this reason ceramic materials such as porcelain have traditionally been made into electric insulators. Some ceramics, however, are excellent conductors of electricity." "Electric conductivity in ceramics, as in most materials, is of two types: electronic and ionic. Electronic conduction is the passage of free electrons through a material. In ceramics the ionic bonds holding the atoms together do not allow for free electrons. However, in some cases impurities of differing valence (that is, possessing different numbers of bonding electrons) may be included in the material, and these impurities may act as donors or acceptors of electrons. In other cases transition metals or rare-earth elements of varying valency may be included; these impurities may act as centres for polarons—species of electrons that create small regions of local polarization as they move from atom to atom. Electronically conductive ceramics are used as resistors, electrodes, and heating elements." Try next time google the topic of your comment first...😅

  2. leaded gasoline=lead going directly to the air->lungs->blood... "Lead will be back in the field" you clearly have no idea... lead from almost century of leaded gasoline use is even in the ocean water right in the middle of the ocean... at the bottom there is clean water but whole surface water is full of lead. Also air is full of stuff from nuclear tests conducted in the air->that is why pre-WW2 steel is so expensive now->u need plenty of air when you producing steel. So no need to worry about lead in this aloy... you wouldn't be able to measure any measurable difference from it to our "Lead FREE" habitat.
