weather....

The wind was brutally cold on Sunday.  Two parties in the barn were not held..on cancelled and the other postponed.  The house is cold.  A decision has been made to hold off on using electricity or propane for heat until Nov. 20.  Of course, that means a fire in the furnace which sometimes doesn't happen.  

As their name implies, the double tetrahedral silicates are complex in structure.  The melllilite group includes gehlenite, akermanite, and hardystonite.  All are commonly found in limestone.  Akermanite is relatively rare in nature but is found in industrial slag.  Hardystonite has been found only in Franklin, NJ.  All are dull in sppearance and to be honest, I have never knowingly seen any of them, nor do I care to.
