I found this website by accident after my granddaughter was looking at some items in my cupboard and decided to be curious about ' old things' as she called them! So we are doing some research together. Must point out that the technical and computer expertise comes from the 7 year old!
The first are 6 glasses marked at the bottom with Reims France and the number 30. I always thought they were Russian Tea Glasses. The pattern is quite raised like it has been enamelled. One has a maker's mark and I have tried to photograph it. They are 50mm dia. and 80mm high.
