Title: New discovery: Monart uranium glass
Post by: Gary on June 30, 2011, 09:09:21 PM
A couple of recent purchases, it was not the common shape of ZA that attracted my interest, but the unusual colour schemes in each of the bowls.The colour code 238 bowl is more lime green than shown, the bubble inclusion covers the bowl completely with none of them burst. The colour code 239 bowl has a white top and the same lime green as 238, if you hold it up to light the bottom half appears to be clear glass with the lime green can only be seen around the top. When viewed from any other angle the lime green is seen throughout the bowl.

Hi Gary,

I have a miniature bowl, shape MC, in this colour way, which doesn't look quite right for Monart, but you have just proved a long held belief. Thank you  8) 8)

Hi Nigel I am glad this was some assistance to you, being able to positively identify your bowl as a Monart piece. This is one of the good things about the GMB, the sharing of information.

One of these I will get going on listing the colours that have shown up since the last update a long time ago. One thing about Monart is that it never fails to deliver new surprises. I guess title could read "Unusual as usual"

This is my latest Monart purchase, a dressing table tray (shape RI). What I would like to find out, is this type of glass named Uranium. I will try and discribe the look of the tray. When held up in the daylight the glass appears to be clear, when put against a dark background the glass is green. My knowledge of uranium glass is next to nothing.

Wow!  :o It certainly looks like it, though named is probably the wrong word.  If it glows a really, really bright green under a UV light, then it is.
This site gives a good summary of uranium glass (aka vaseline glass) http://www.vaselineglass.org/

It does indeed look like it's uranium - and it's just glorious!

Post by: Paul S. on March 21, 2012, 08:23:00 PM
that edge colour is a dead ringer for u.          Try it in the sunlight tomorrow morning (if we get any), although you'd probably get more sunshine in the other Perth. ;)

The sun is shining brightly in the Fair City of Perth this afternoon and I took the tray outside to the back garden and the tray looks much greener in the sun light.
Thanks Christine for the link on uranium/vasiline glass, most informative, I agree Sue it is a glorious piece.
The link below is a previous thread, pre my new but limited knowledge on uranium/vasiline glass.

Looks like that might be uranium too.  :o You need a little UV light to check and I need a piece of uranium Monart...
Title: Re: Monart uranium glass ?
Post by: Gary on March 28, 2012, 07:19:22 PM
I borrowed a UV light and tried it out on all three Monart pieces and all turned bright green.

Three pieces? I see only two.
I don't know if D&D have any uranium Monart. I shall have to ask!

This is a new one on me. If I find a bit, Christine, it's yours!  :-*

There are two in the linked thread; similar shapes but slightly different decor

I thought that was different images of the same bowl - I had trouble following the text - my problem, not anything wrong with what was written.
Title: Re: New discovery: Monart uranium glass
Post by: Gary on May 14, 2012, 11:05:39 AM
In the Ian Turner Sale of his Monart glass there is definite instance of uranium glass and one possible case.
The definite one is in lot 21 a RI tray with the colour code 248 this is the same colour code as my RI tray (though it is a different size code). Lot 21 does not show up on Christies web site but there is a photo in the catalogue of the tray.
The possible one is lot 70 a Z shaped ginger jar. Gary

Certainly looks possible Gary
Title: Re: New discovery: Monart uranium glass
Post by: Frank on July 11, 2012, 12:49:51 AM
I must have tried with UV lamps long ago but don't recall getting any reacting so rarely bothered but I guess there were quite a few around in those colours. Just never seemed as interesting then as it does now with all the U interest.
Title: Re: New discovery: Monart uranium glass
Post by: Gary on August 02, 2012, 09:16:33 PM
Frank the ginger jar in the Ysart Glass book (page 71 plate 49), looks like the same decoration style (coloured whorls and clear) and colour scheme as the RI uranium tray with the colour 248. Is that ginger jar the same one from the I Turner collection sold at Christies in 2003.

I don't think so, probably went to Parkington or Perth Museum... grey cells to foggy  ???
Title: Re: New discovery: Monart uranium glass
Post by: Gary on August 29, 2012, 01:10:46 PM
Not in Perth museum, I have viewed the Monart glass collection twice and photographed every piece apart from what is on display and a couple of AF bowls and some Y pin dishes (fairly ordinary pieces).
Gary
Title: Re: New discovery: Monart uranium glass
Post by: Frank on September 06, 2012, 11:45:27 PM
Maybe Ian bought it in the Parkington sale.
Title: Re: New discovery: Monart uranium glass
Post by: Gary on November 02, 2013, 08:57:10 PM
Below are two images of my latest purchase, it is Monart, shape code IG size code 1V (12 inches wide) colour code unknown,citrine with orange and yellow splashes with bubble inclusions.
When I purchased the piece the vendor mentioned he thought it possibly was uranium glass.
I borrowed a UV light today and it is indeed uranium glass.

Thanks Nigel, I am well pleased with the bowl.
The colour scheme (IMHO) shows Salvador at his most creative.
Gary
Title: Re: New discovery: Monart uranium glass
Post by: KevinH on November 05, 2013, 06:23:46 PM
Gary, your photos of the bowl probably confirm something that has been noticed with some millefiori canes.

The green of the glass in the bowl appears to be like that of a cane centre that has been seen in one or two canes in paperweights. Looks like this is a nod to a cane or two being made using the uranium glass rather than the usual clear glass for the central element.
Title: Re: New discovery: Monart uranium glass
Post by: Lustrousstone on November 05, 2013, 06:41:15 PM
Looks like yellow uranium to me...
Title: Re: New discovery: Monart uranium glass
Post by: Gary on November 05, 2013, 10:28:20 PM
With the UV light on the bowl it shows up green, especially where there is clear glass in the bowl (which there is some), and a green hue shows through the original citrine (yellowish) colour of the bowl with UV light.
Gary
Title: Re: New discovery: Monart uranium glass
Post by: Lustrousstone on November 06, 2013, 07:35:02 AM
That I would expect but the base colour is yellow. Kev is talking green. This has uranium in two canes but pale yellow I think, it's very difficult to tell (the green bit isn't uranium in those two canes) http://lustrousstone.co.uk/cpg/displayimage.php?pid=1832
Title: Re: New discovery: Monart uranium glass
Post by: KevinH on November 06, 2013, 05:54:12 PM
Hmm, yes ... or no .. ???

The cane centres in weights (all two of them) that I have seen were an obvious transluscent bright yellow-green and they reacted quite strongly to longwave UV (again with a bright yellow-green colour). In Gary's bowl, I see the colour of the main parts as "translucent yellow-green", hence my comments.
Title: Re: New discovery: Monart uranium glass
Post by: nigel benson on November 07, 2013, 01:06:30 AM
Hi,

It seems to me that the IG bowl is a difficult thing to photograph to show the green uranium that I suspect is the base colour. I think it's being masked by the ochre and bubbling as well as the slabs of yellow and orange/red enamel decoration.

Oh, try clicking on the third image down here: http://www.20thcentury-glass.org.uk/ (http://www.20thcentury-glass.org.uk/)

Check the green glow to the lower right of the image.

The Monart green uranium I have seen was definitely green - that looks like what I call pure uranium and much more yellow than green, especially when out of daylight
Title: Re: New discovery: Monart uranium glass
Post by: nigel benson on November 07, 2013, 10:25:47 AM
OK, I was just trying to help (having handled the piece) - which is great to photo as an item, but not to show what we're discussing here.

My latest piece of uranium Monart glass. The shape code is N colour code 295A and size V1 (9inches tall).

0OOh - yours has the same cloisonné effect - it's like a cross of my FA and OE!  ;D (pictures to be added later)
I didn't expect that.
Does it glow green or is it yellow - looks like it should be yellow somehow. Didn't expect it to be that size either  - is it quite thick glass?
Wow  ;D

It glows green with UV torch in the dark.
It is fairly thick glass even for Monart, I have noticed with shape N( the ones I own or have handled) they tend to be thicker than normal.

Thanks Carolyn it is a stunning colour scheme, among one of Salvador's finest.

I've been visiting Perth Museum again. This time, I took the good camera with me (and got myself stuck between cabinets, crawling all over the floor - I have no shame) with Michael holding the UV torch to try to get some better images of the big cylinder vase.

It's unfortunately at the back of the cabinet - and not properly lit, the lights miss it.
Title: Re: New discovery: Monart uranium glass
Post by: orangeglass on June 22, 2014, 07:30:05 PM
great pictures Sue!
The cylinder vase is exactly the same colour scheme as my vase, but mine has less blue and more like the top part of the cylinder vase.
I can see clearly now the chalice  "combing" (is that the correct term?) effect on it.
Thank you for your efforts - really must get north of the border when I can  ;D

I had a tiny stroke of good luck in a charity shop just before we went to the museum. I found a pink Monart pin dish - exactly the same as the one on display... I was wandering around with it in my hand - and nobody noticed that I appeared to have appropriated an exhibit.
First trial for my planned daring attempt to liberate the cylinder successful.  ;D

Yes, the chalice came out really well - (I had the good camera with me, thanks to Lustrousstone for that) and yes it's called combing.


I managed to get a nice pic of this vase - but it's not Uranium.
Title: Re: New discovery: Monart uranium glass
Post by: Frank on June 24, 2014, 10:13:42 AM
It is not combing which is achieved with pulling a combing tool. More a ribbed dip mould decoration.
Title: Re: New discovery: Monart uranium glass
Post by: orangeglass on June 24, 2014, 10:34:20 AM
I assumed the ribbed mould created the more obvious lines, but how are the "wiggly" lines going the opposite way created - this is what I thought was the "combing"?
Is it all done with ribbed moulds then?

Thanks for any info,
Roberta
Title: Re: New discovery: Monart uranium glass
Post by: Gary on June 24, 2014, 07:11:09 PM
As far as I am aware the vertical lines and the horizontal lines are made in the same ribbed mould (not at the same time), like the one shown below.
The other two images is of the goblet, one of the inside of the goblet and a side on view.
Gary
Title: Re: New discovery: Monart uranium glass
Post by: Frank on June 27, 2014, 01:10:25 PM
Yes the piece is twisted after dipping and then twisting in the opposite direction after second dip. Colours being marvered before dipping.

Combing can only pull-úp areas of colour whereas dipping concentrates colours without much pull-up, but obviously there is some pulling with second dip.

The cylinder would really come to life if it had lighting above it the way the chalice does. But it's at the back of the cabinet... :'(

Post by: helenaJ on September 05, 2014, 08:29:37 PM
Although it's not a good photo this is the UB bowl referred to by Gary Millar in previous discussions and the uranium element was discussed many, many years ago by several other Monart collectors.
