Title: Opaline posy vase ?
Post by: bat20 on September 10, 2021, 11:04:09 AM
Hi all , this little vase has a broken pontil and a green tint to the glass , I’m used to seeing Walsh Walsh  straw opaline pieces, but I’m not sure if they used different colours ? Any thoughts , thanks .

Hi, might it be a leech jar?

Hi - have you put the u.v. torch on this piece?                     It might well be a leech jar or posy vase, but is it really opaline?         Opaline isn't simply coloured glass, and can't ever recall seeing opaline in the bi-coloured state i.e. part clear part coloured - the green here is almost what the States guys call vaseline, though it won't be if the green doesn't glow :)

It's opalescent rather then opaline. I suggest that possibly English is probably as good as it gets.

Think it is a leech pots, have a look at the seventh photo down here: http://www.gardenwithindoors.org.uk/leechpots
I would much prefer a leech pot to a posy vase.

My money is on it not glowing under  uv light. I have a similar coloured bowl which is not uranium, although there must be exceptions.

despite Christine's comments  -   usually more knowledgeable than mine, I'm wondering if that circular appearance to the snapped point scar, is the result of a hollow pontil rod rather than a solid one.         Continental rods - so I understand - were sometimes hollow.            Just a suggestion - what do folk think? :)

Thanks for replies ,it doesn’t glow. I’m never sure about labelling these things as leech jars after a debate on here about them, I think someone thought they maybe seed jars ??

Paul, you're right, Biot glass in particular transferred pieces from the blowpipe to another blowpipe rather than a solid pontil rod to do the finishing work to the rim etc. This left a circular pontil with the same smooth finish to the glass inside and outside the ring. They also domed the base to prevent the pontil mark from damaging surfaces. This piece appears to have both these features although the pontil does seem a bit crude.

This type of pontil scar seen frequently on bottles/ flasks blown in piece molds and pattern molded in dip molds [ in USA]. Dating roughly 1820s to 1870s. So much so that collectors have designated it a " tubular pontil ".

You would think seeds would be sold in paper bags or envelopes (like today)...but you wouldn’t  want to trust a leech in a paper bag ;D
