  So, is all purple glass old?
             In a word, "NO!"
 
    Well then,is all "sun-purple" colored glass old?
               In a word, "MAYBE"--
 
   
Please study these 3 photos carefully......
---Above are 2 creamers in the EAPG pattern, ROSE POINT BAND. The one on the right
is the beautiful clear glass and the one on the left has been artificially turned a washed-out purple.
---Above is a color plate from an L. E. Smith Glass Co. current production catalog. Reproductions of Early American Pattern Glass in the exact color of the "sun-purpled" pieces are now being sold. And Arcoroc is making pressed glass in a color they call "Antique amethyst" -- so the color can NOT be trusted to tell the age of pressed glass. If you truly just love this purple, why not buy glass made in the color rather than promoting the turning of American historical glass purple? ---Above is a grouping of beautiful genuine amethyst color EAPG in Swag with Brackets, Croesus, Argyle, Hobnail and Cathedral patterns.
Has all "sun-purpled" glass turned that color by the sun?
      In a word (or 2)   "ABSOLUTELY NOT"! It is most often turned purple by putting it in a box for a few weeks under a lamp which was intended to kill germs by ultraviolet radiation. That is why we have "sun-purpled" in quotation marks. **
Does all old glass naturally turn purple in the sun?
       Some does and some doesn't. It depends on what the meaning of "old" is and what the glass formula is. Some will tint slightly if stored near a sunny window and this is regarded by antique glass folks as "discoloration". All discolored antique glass is devalued which is why it is advisable to not store old glass where the rays from the sun can adversely affect it.
Is "sun-purpled" glass a good investment?
     On the contrary, it is tantamount to purchasing a piece of damaged glass and the value is decreased as though it had a serious crack or chip.

Why is clear Early American Pattern Glass being turned artificially purple?
     Because presumably the people who turn it purple don't respect history or care that they are ruining an historical artifact & the people buying it don't know that they are purchasing a formerly valuable, but now worthless, antique.

I'm told that the process of turning antique glass purple is not an important issue because the process is reversible by reheating the glass. So what's the big deal?
    Unfortunately your source for that information is not alone in believing that but is DEAD WRONG. Hundreds of folks have made that claim to us but not ONE has ever demonstrated a successful reversal to the original state of the Early American Pattern Glass. If you believe you will be the first, please properly document your effort and let us know. EMAIL US

PS We actually have had one response to this challenge which claimed to have successfully turned sun-purpled glass beads back perfectly clear.... at which point they were totally melted.....

One of the sad consequences is the incidence of fraudulently advertised "new" colors of a pattern.  Collectors have been known to purchase what they are told is a newly discovered color in their pattern and find after having paid a premium price for it that it has simply been "nuked".

Our thanks goes out to Sara Thurston of New Jersey who has joined the chorus of those who
are working to help discourage the practice of turning & collection of "sun purple" EAPG.

**Please note that these comments re "sun purple" glass do not reflect negatively on folks who
have had EAPG for years and accidentally left it near a window allowing it to turn a
" tinge" of light pink or grayish purple. And they certainly do not intend to diminish the intrinsic
value of inherited glass. Our anger is directed at people who are purposefully turning
pattern glass pieces purple with a profit motive in mind..

By now all antique shop and mall owners know that when they allow the sale of "sun purple"
pattern glass, they are contributing to the ruination of American treasure.
      PatternGlass.com encourages the boycotting of all shops and malls
allowing the sale of this glass on its premises.

Not content with the mealy "sun" purple color, they turn old glass a deep, deep purple by some sort of radiological means according to the owner of this shop in east LA. It was difficult to photograph, but there are pieces of Early American Pattern Glass on these shelves the color of the jars, except the pattern glass is thicker so the color does not photograph as well and the thinner jars.
And Dallas is participating too.  Here are photos from a case in
a large antiques mall in Dallas in January 2006.  On the left are old
bottles and on the right are 2 EAPG cruets, a lamp and a fly catcher.
