Do you have pictures of the other ones you own with fire polished rims ?

I only own three, as far as I can see.. one is the largest Aurinkopullo, the others a Pagoda and a Tornado. 

I believe the Rulla also has a firepolished rim, but unfortunately I don't own one :(

Hi
Surely they're ground tops?

I thought a  fire polished top is very rounded, much more 'organic' ?

I'm sure you are right and my experience and knowledge is very limited so I
 am probably confused!

 I do have Scandinavian vases where I am certain they have a ground and polished rim (one being an Alvar Aalto savoy vase for example and another example being the one I first posted in this link) and then I have some Aseda vases and these two that I assumed were fire polished because of what they look like.  But looking again perhaps I have thought that because they are so much thinner walled than the others and so they don't 'look' ground flat and polished to me  I'll take some comparison pics later and post them so I can understand better - my apologies if I have confused anyone :-[

I have one of those in your picture of three shelves of green vases, bottom shelf sixth from right. That has a rim that I would say has been ground and then fire polished. It is flat but has no edges.

This is the only Riihimaki vase I have had out of around fifty or so which had a fire polished rim: http://www.glassmessages.com/index.php/topic,33243.msg181155.html#msg181155

The others all had rims which were ground flat and polished, this one had a rim that was semicircular in cross section and was obviously different from the rest.

Yes, the Solmuke, and in fact a fair few that possess a name rather than a number, are more likely to have fire worked rims, along with the ringed base ?

(but like the Whitefriars pontil, this doesn't appear on everything by any means)

The 'export' vases, as lovely as they are, were fairly low-cost pieces and I shouldn't have thought warranted such a treatment, cost-wise ?

This is how I understood fire polished to be?

see here where there is also an example of a ground and polished rim.

http://www.blenkoarchive.org/blenko_characteristics.htm

On this basis I am pretty certain that both my other Riihimaen Lasi Oy vases have a fire polished rim  :-\

Would I be right in thinking that cold working the rim by grinding and then polishing would be more intensive and expensive than fire polishing it?

I'm really not sure!

 I always assumed furnace work was more skilled, and therefore more expensive, than machine work ?
I'm confused now  :-\

It's not furnace work. All it requires is a very hot gas flame. At Dartington Glass, they have a rotating gas-fired machine into which they pop the glasses after a preliminary grind to level the rims and that fire polishes the rims.
