Glass Etching
History
-Glass etching started around the 15th Century. Artists
scratched directly onto cast or hand-blown glass,
creating designs, motifs and pictures.
-Acid etching was developed in the 1860’s and the
cutting was finer and more exquisite.
-As the types of acids used in this process were
extremely hazardous, a mould-etch process was
invented in the 1920’s and later widely used in the
1930’s. Moulds were used to mass produce etched
glassware and later became known as Depression glass.
So what is Glass etching?
Glass etching is: The process of treating areas of
glass to create a roughened, frosted glass design.
We will be using Glass etch cream: It has a
diluted acid that lightly eats away at the
surface of glass.
But what images do we want to put on
our glass?
We will be looking at the art of
• Positive space and
• negative space.
So what is Positive and negative
space?

Negative space is, quite simply, the space
that surrounds an object in a image. Just
as important as that object itself,
negative space helps to define the
boundaries of positive space and brings
balance to a composition.
Positive space : the definition of
positive space is the area or space on a
painting or piece of artwork in which is
occupied by the subject.
When you start to make more complex
pictures using shapes you can create
images like this.
We will be looking at Polynesia
and Oceanic Art, sometimes called
Tribal Art.

-The advent of Christianity in Tonga witnessed the loss
of several indigenous practices such as the practice of
tatatau or tattooing.
-Although the art of tattooing was retained in the nation
of Samoa, it was completely erased in Tonga.
-However, the art and practice of tattooing has been
enjoying a revival in Tonga in recent years. This is a
result of the work of scholars, researchers, visual artists
and tattoo artists such as the two brothers – Carl and
King Afa Cocker. Carl and Afa’s knowledge of Polynesian
art and culture – specifically the art and tradition of
tattooing
Tongan warrior complete with his sharks’
teeth necklace, a war club and the traditional
warriors tattoo. Notice that the tattoo covers
half of his body with solid black. This particular
type of tattoo was symbolic of defiance and
self confidence in the face of the enemy.
(1827)
This is from an engraving of a Tongan man’s
thigh. This picture, drawn from life during
Captain Dumont d’Urvilles voyage of the
Astrolabe, is the only visual account left of a
traditional Tongan male tattoo.
Companies use negative and positive
space to send messages and even hide
meaning.

Something you might notice is
happening with this project is …
• Pareidolia (/pærɨˈdoʊliə/ parr-i-DOH-lee-ə) is a
psychological phenomenon involving a vague and random
stimulus (often an image or sound) being perceived as
significant, a form of apophenia. Common examples
include seeing images of animals or faces in clouds, the
man in the moon or the Moon rabbit, and hearing hidden
messages on records when played in reverse.
• The word comes from the Greek words para (παρά,
"beside, alongside, instead") in this context meaning
something faulty, wrong, instead of; and the noun eidōlon
(εἴδωλον "image, form, shape") the diminutive of eidos.
Pareidolia is a type of apophenia, seeing patterns in
random data.
So what we are doing today?
• We are going to experiment with paper and
create designs that use positive and negative
shapes.
• On your paper I want you to play with using
shape to make an image.
• If you get ideas for your final design, I want
you to draw them in your sketch book.

The Etching process.
1: Plan out a design you want to do and sketch it out.
2: Create a stencil of the design you have created.
3: Wash a glass in warm, soapy water and dry it
completely.
4: Apply your stencil to your glass.
5: Make sure every edge of your stencil is firmly
stuck to the glass.
(if you do not do this your design will have bad edges.)
6: We will use a brush to apply a thick layer of
etching cream to the exposed glass. And let it sit
for 15-30 min.
7: Rinse the cream thoroughly with warm water.
Remove the stencil.
