[Avodah] alloys/mixtures/compunds

[Eli Turkel]

Alloys, such as steel or 14K gold, are made up of grains, and each
grain is a crystal containing only one element.  The size of the
grains may vary depending on how the alloy was produced.

Things like ceasarstone are made from separate pieces of stone held
together by a resin.

Of course the pieces in ceasarstone are much, much bigger than the
grains in an alloy.  Also, the grains are held together by chemical
bonds, not by some type of glue (resin).>>

Of course the question is do these differences affect the absorbility
of the material and did chazal look into the details of mixtures as
is done today.
