Is this one really only 6.5 cms. tall? Some people here have spilled gallons of ink discussing the definitions of some of these names.

The general appearance of this and many very similar vases, often showing enamel painting, probably do come from eastern Europe, though couldn't say who made them to save my life - they turn up commonly in charity shops even now though not so frequently - have to say I always had them down as low end of the market, but even lowly vases need someone to love them.
Obviously not opalescent - think of Jobling, Burtles and Tate and those large pike - that stuff can be seen a mile away.
According to Mark West, the real C19 opaline - think of Baccarat - have the sunset glow/fire due to the inclusion of gold oxide added to the mix/batch - I take his word for it.
Opal was one of the names that Sowerby gave to a particular plain white opal-shade of opaque Vitro-Porcelain - though I'm sure it's an oft used word covering many things - too good a word to waste probably.
In glass the fiery glow was also created by the addition of phosphate in the form of calcined animal bones (does calcined come from calcium?),
though apparently later opalescent glass used phosphates of alumina and fluorine - so the book says.
My suggestion would be that this is simply an opaque vase that had the inclusion of phosphate of some kind added to the mix, to give the glow, but shame the gilding has mostly gone. Not a clue as to age, but might have suggested early C20, but you sound confident with c. 1890.
Perhaps it's now time for it to hold some flowers
