Not sure what it is so not sure how to clean?

[thinkingit]

Is this what they call sick glass?

 

[thinkingit]

Also, would any kind of lime a way or CLR help?

Hi thinkingit; It looks like you have a nice BIM -(2 part mold) demijohn. I would like to see a closer picture of the finish and a picture of the bottom. These would verify the applied finish that I am sure it is, it would also show any uneven sloppy glass under the tooled finish. The picture of the bottom would tell us more about the making process. I like these bottles, because they were made all over the world and traveled the early world liquid needs. RED Matthews

I'm not a bottle person so part of your reply is in a foreign language to me. Ha, ha...here are the only pics I have with me. Can you tell if the bottle is "sick"??? or can it be cleaned with one of the above methods such as lime away?

I can't tell from the photos if it's sick glass or not. If the muriatic acid didn't even make a dent in it, then it's probably sick glass.

It doesn't hurt to try CLR, as CLR is safe for glass. But I suspect your likelyhood of success is small.

CLR usually requires some rubbing. A sponge or rag on a coat hanger might help, but be careful not to let the sharp edge of the coat hanger scratch the glass. If the CLR doesn't work, maybe some steel wool on the end of a coat hanger will do the trick, although it'll take an awful lot of patience. Fine grain steel wool shouldn't hurt or mar the glass at all.

Well I am back to you thinkingit; First of all I doubt it the glass is what I would call sick. It is hard to tell what it has had in and around it. "Works' helps some times. Another thing I have used on stubborn glass is a product from Walmart for cleaning false teeth;"Stain Away + (plus that is.)
Your finish picture looks quite clean. It might not even be tooled - you would see the circular lines horizontally around the finish if it was applied and tooled. I just couldn't tell.
The bottom picture didn't tell me much either.
It is still a neat demijohn. RED Matthews

It might be hard water stain, scale in its first stages, in which lime away couldnt hurt, as the Jewish mother says about chicken soup, what could it hurt?????
