It pays to Re-Google

While waiting in a doctor's office today, I re-googled Ezra Riley on my IPad.  I haven't googled him in a long time and I found something new.   Ezra received a Patent in 1873 while he was the manager of Pontnewynydd Iron Works in Wales.

From Wikipedia: The puddling furnace is a metalmaking technology used to create wrought iron or steel from the pig iron produced in a blast furnace. The furnace is constructed to pull the hot air over the iron without it coming into direct contact with the fuel, a system generally known as a reverberatory furnace or open hearth furnace. The major advantage of this system is keeping the impurities of the fuel separated from the charge.
