Dear Joey,

Thank you for the answers. Yes, the otoscope is for checking the ears. I got a retail version with a plastic head and led cool light. It works well enough for the price of under 40 to look at portions of the inside. (copying Giovanni's inquisitive spirit)

A really nice tool will be the military grade borescope with the adjustable fiberoptic heads, the ones they use in movie to see what is going one in a room by inserting a thin tube under door, or a small opening.

Then I understand now, the ones I have are really modern tourist ones (no bubbles on the cloisonné mini vase and enamel over coppers anywhere). They must had pour the left over glaze grinding back in or never bothered to empty it after grinding. That is why there is glazing on the inside with mixed color and transparent with metal showing. 

Another mystery for me solved, thank you.

With gratitude,
David
