Solving the Mysteries of Glass

One of the absolutely most fun and amazing thing about collecting china, porcelain or nearly any kind of glassware is the mystery and the hunt to find the things you don’t know about it.


 
The bottom of your new piece of glass will, in nearly every case, offer you some kind of mark or another. These marks, whether they are shapes, numbers or letters will offer you fascinating clues, pieces of the puzzle as to how old your piece is, who made it, what company produced, it, sometimes even what furnace it was fired in, but sometimes even the exact year and the exact employee who made the piece you are holding in your hand.
Marks on your glass hold clues, or entire answers to some wonderful information for those who like knowing what they have, but more, who just like digging for obscure truths.

Some examples of this are:
You purchase a vase at the local garage sale, a large letter H on the bottom tells you that its a Hadley vase. Hadley was considered to be one of the best ceramics workers of the entire 19th century, so having found out that he worked in that time span, and that he also worked for Royal Worcestor, you know something already.
Later in time, his painted rose designs became known as Hadley Roses, for their beautiful soft colors.

His death in 1905 did not stop production of his products, with the molds being purchased by Royal Worcestor, so you aren’t certain when this one was made.

YOu can sort that out by viewing the number of dots that are going around the words Royal Worcestor.

Every dot represents a year.. beginning in 1891, therefore, if you have a piece of glassware from this company, the words Royal Worcestor, with 12 dots around it, will mean that it was produced in 1903
(1891+12=1903)

Nearly every type of glassware that you purchase will give you these kinds of clues. To begin with , start by researching what that single letter may mean, and then move outward from there.

  1. I bought a beautiful, slightly opaque pink glass vase with small raised flowers on the surface at an estate sale. On the bottom is a raised mark that looks like a bull or possibly deer, with short, curved horns that point inward over its head. That’s all, no words or other marks. Any idea who uses or used this mark? Thanks for any help!

  4. I have a small clear glass dish. It is round, but there is no side on it. I think it might be a candy dish. It has a flower etched on the side of it and it is a murky white color. There is a letter “T” on the bottom with a small marking on either side. I found a picture of the symbol at this website http://www.glasmarken-lexikon.de/marken.php?k=Buchstaben+ohne+Umrahmung%3BA-Z&b=t . It is the picture at the very bottom second from the right. However, the website will not give me any information on the artist. I was just curious about the artist was and how old the dish was. I would appreciate any help. Thank you!

  12. I have a pair of clear glass fish (like sunfish) that were my uncles who passed away last year at 91 years. He and his wife never had children. I did his estate sale and these fish didn’t sell. I had them marked at 40.00 but I think they are genuine old Murano. There is an impressed mark on the bottom of the bigger one. I read that the older pieces could have been sandblasted or have an etched marking at the center of the base. This mark is about 1/2″ long x 1/8″ wide and looks like an oblong teardrop. My uncle must have scratched his SS# on it as there is a 9 digit number on this piece as well. Will have to ask my mom about that. The pair are in perfect condition – no chips, scratches, etc.

  16. My grandmother has a vase passed down for many generations, my grandmother believes this vase to be nearly 100 years old. We have searched the piece and can not find a mark on it indicating the maker. My grandmother vaguely remembers someone mentioning there is a history behind the vase however, all that know the history have passed on, this piece is possibly made from coal. How would I go about finding more information about this piece?
