It will also be noted that all examples exhibited some or all evidence of porosity, casting flash and gas bubbles (appearing as small granules of silver adhered to the model). It was the Schmutzler ring that exhibited the largest degree of casting flash, porosity and gas bubbles.

I have only held a few examples of different HRs Don has showed me at a few shows,but never have looked at them using a loop or a Dental scope like people use now on daggers and such,but on the ORIGINAL RINGS you have, or have looked at have you found any such "flashing and porosity" as Peter did in the rings he checked for gottlieb?

Thanks again
