It is sometimes difficult to tell the difference between crystal and glass. To make it easier for you, you will see in the following article some tips that will allow you to certify the authenticity of your crystal objects like the Engraved Crystal Glass.
Take a look at the
signature or stamp
The first thing to do to find out if your items were actually
made using a crystal is to check if they are signed. In general, the most
reputable large manufacturers tend to coat their works with a stamp which has
been engraved by sandblasting. This imprint not only allows knowing the origin
of the crystal but it is also considered as being a guarantee of quality. As
you have seen, the stamps are often placed on the side or under the object. It
should be noted that the old crystal pieces do not have signatures, but a small
piece of round paper stuck below the object. In this second case, it is a
little difficult to recognize the authenticity of the crystal. You are thus
advised to consult the professionals.
Check the refraction in
light
Thanks to the lead oxide it contains, the Engraved Crystal Glass can reflect an
extreme brilliance. This phenomenon is especially visible during contact with
light or with the sun's ray. Indeed, this element will break down the spectrum
of light like a rainbow. It should be noted that during this small test, you
should under no circumstances see a green or grayish appearance. Otherwise, it
would mean that your crystal is of poor quality or that it is simply a glass.
If you have any doubts, do not hesitate to seek the advice of an antique dealer.
Other tips
Aside from these first two tips, there are still other ways
to tell if your coins are real or fake crystals.
Test the sound:
A good quality crystal generally evokes a clear and pleasant
sound to hear. Compared to the sound of a glass, hers lasts a little longer.
This sound manifestation can vary from one crystal to another because it is
influenced by its thickness, structure, finesse, and shape.
Remember to check the
finish of your items
It is important to inspect the finish of the edge of the
crystal as it will also help you know the value of your coins. For these types
of glass, there are two types of polish. The first is to obtain a flatted edge
or a flat edge with chamfer. And the second is to give the crystal a slightly
rounded outline.
