Oh by the way, I am quoting those prior to 1900's. Companies continued to make the same pattern's until the 40's in which case they would be much less than that. I am assuming they are christmas bulbs and not float's for a net or even the very early fire bulbs. These were filled with a chemical, they were in-cased in a glass bulb and they would be used to throw into a fire, upon breaking they would release the chemical to put the fire out. If you have one of these now, they sell pretty good. We sold a mint set of them in the wooden case for 800 dollars US but they were rare colors.
