Title: Is this Bowl *Alabastro* ??
Post by: antiquerose123 on January 03, 2012, 07:41:38 AM
 :hi:  Was wondering IF this bowl is Alabastro .....if that is what it is called.....??

It is kinda kidney shaped with 1 fold.  It is a pretty pink color.  Size is about 6.50 inches by 5.25 inches and about 2.75 inches tall at the tallest point.  Weight is almost 2.50 pounds.  Bottom does show wear.

(Seems I am getting a few Pink things here -- they will always go with my Pink Lamps....LOL)

Any ideas on the maker, or the age?  Thanks as always  ;)

I'm probably going to get this wrong Rose but I would say not, I would say that is opalescent glass....and very beautiful it is too!  :sun:

Definitely not alabastro. Alabastro is opaque. I agree with flying free, though I'm staying away from the "o" words today.  ;D

Umm, I don't think it's opalescent, I think it's opaline and pink.
But I've been sticking my neck on the line today anyway!

 ;D I still think it would be described as opalescent though - but I could be wrong  :ooh:
there is a description on the ddoty website if you scroll down on the right hand side, a description of 'opalescent' and a good picture of a footed bowl.

That is certainly like this bowl, pink with milky bits, but perhaps the use of the term there might be confined to carnival glass - or it may be an Americanism, m. (like "vaseline" for clear-milky uranium glass, but not for uranium custard glass)

To me opalescent glass is the stuff which is coloured with arsenic, and gives "fire" when light comes through it. It is milky opaque, with blues, yellows and reds showing, depending on the thickness of the glass - that's the fire.
It's the stuff typically used by Sabino, Jobling and Lalique - as well as others.


I don't think  :spls: glass coloured with arsenic is used in carnival glass - it would be a bit silly, given the lustre-ing would cover it up!

ah, I thought opalescent glass was glass which contained bone ash  :-\ and I thought it was that which caused the 'fiery' opalescence when held up to the light.

Maybe they are the same thing, but different words?  :help:

I'm sure one is just milky white while the other has fire.
I looked up Ivo's "Fact File" last night but I'm still not sure what's what, and now I'm not at all sure whether or not the stuff with fire is made with potash or arsenic...... :ooh:

But potash isn't arsenic. Potash has potassium in it. (Potassium hydroxide?). Arsenic is another metal entirely.

It doesn't look satinized to me, but I agree it is one of the "o" words.

I am really going to have to learn my *O* words here.  I am always confused  :ho: on this matter. :thud:

I did some online dictionary work on this the other day. There are two "schools" of thought on the words. School 1: According to Oxford & Webster, opaline and opalescent are synonyms. School 2: Some smaller online definition sources have that opalescent means having colorful iridescence. (The trouble here is I found a couple of things that mentioned this for opaline. :help:)

I think I will personally use them as synonyms. If it's good enough for Oxford and Webster, it's good enough for me. I do reserve the use of the "o" words to glass that is milky with an opal appearance. I call the pure white glass lattimo or milk glass. (Or if it is colored, I call it colored lattimo or milk glass.)

I'd like to get a person who understands glass chemistry to comment. Where are our glassmasters when we need them?

I *think* there is a good descriptor here of opalescent glass (but I'm open to correction  :) )
You need to read down a bit but I didn't want to risk copyright by cutting and pasting.
