This presentation of Glass Blowing was an assignment to meet specific objectives: Use PowerPoint presentation to demonstrate how I do one of the arts. Include in the slideshow: 1. Selection of one the arts and why you chose it. 2. Images of you working on your selected art. 3. What you had to do to learn about the art. 4. Your reflections about this experience, both as a student learning it and as a teacher who might teach it in the future.

1. GLASS BLOWING
Beginning glass
by Deann Lineback

2. GLASS BLOWING
 I chose glass blowing because it is a course I
am currently enrolled in at CSU Chico.
 This is the first time I have ever worked
with molten glass.
 I am in the process of learning the terms
and skills it takes to make a simple glass
cup.
 Glass blowing is an active, hands-on art
that requires craftsmanship, dexterity and
agility.
 I have begun to truly appreciate glass
blowing as an art since taking this course.

3. FIRST THING FIRST
 Knowing terminology of glass blowing
•Blower – The glass
worker that blows
the air through the
blowpipe (within the
mold or freehanded).
That’s me!

4. TOOLS TO USE
•Bench - The bench is the center of the hot Shoppe. It is where the artist
works a piece and is the where all the tools are kept. The bench has two rails
spaced on either side going perpendicular to the seat; these rails are used to
roll the glass pipes on.
Bench
•Jack - Large tongs that are used in order to
create score lines in the neck of a piece.
Pincers Making a Jack line is often the line.
•Pincers – Glassmakers tool for
picking up, transferring and applying
water to the Punty to remove the glass
piece from the pipe of blowpipe.

5. TOOLS CONTINUED…
•Block – The forming
tool used for the
shaping of the molten
glass. The “Block” is
usually made of cherry
wood and is “wet” while
used with the hot glass.
BLOW MOULD
•Blow Mould – An open ended cylindrical designed to create effects or
grooves in the molten glass by blowing into the blowpipe while in the
mould vertically.

6. TOOLS CONTINUED….
•Punty - A solid
steel rod that is

the mouthpiece and the other has the larger
built up area for the molten glass to gather
and blow the bubble on.

7. MORE TOOLS CONTINUED…..
•Pot – A holding area •Glory Hole – The opening of the furnace used
for molten glass where to keep the glass hot and workable. Several

•Yoke - A stand in front of the glory hole that is
used as a support for the blowpipes. Using ball
bearings it allows the artist to turn the pipe easily
with little effort giving them a chance to regain

strength.

8. SO MUCH TO KNOW!....
•Parison – The first
small bubble at the end
of a blowpipe.
•Gather - Placing molten
glass on the end of the
blowpipe or pipe for the
further development of
that glass project.
•Gathering - obtaining a
layer of clear glass over a
subsequent layer of glass. Tiny air Bubble

FIRST
GATHER

9. AFTER SECOND GATHERING, SHAPING
OCCURS
This can be done with the wooden block shaper…..
~OR~
By rolling the molten glass
on the marver.
•Marver – A flat steel plate that’s used for the picking up color chips or the shaping of
molten glass on the end of a blowpipe or pipe with a rolling action. A Marver can also help in
the uneven cooling of the glass for a desired effect.

OF THE BLOW PIPE BEGIN TO BLOW!

•Reheat - to heat the glass
back to a molten state; usually
done in the glory hole.

11. I’M GOING TO USE THE BLOW MOULD
Stand on
tippy
toes and
blow Then flash!
HARD! Then blow out air bubble
•Flash - A quick reheat in the glory hole in
order to keep a part of the glass from getting
too cold.

12. READY FOR JACK LINE
The crease line that will be used to
separate the glass work from the
blowpipe is made by the Jacks
•Neck - The edge of the piece that will be scored
and separated when transferring the working
piece onto the punty.

13. TIME FOR PUNTY…AND TRANSFER •Wetting Off – The
separation line for
the glass work from
the blowpipe using
cold water to fracture
wetting control the break
Punty onto bottom of glass piece usually done by
dipping the pincers in
water and droplets
touch the neck of the
piece.
These are not mine,… I lost my piece
Then flash. when I tapped it off the blow pipe .
next: open the top with (that’s the “breaks” ha ha)
the Jacks.

Continue to shape top.

14. TIME TO ANNEAL
When you’re satisfied
with shape then place in
the annealing oven by
wetting off your piece.
•Annealing Oven – The process of gradual cooling of the outside
and the inside of the molten glass to assure that the glass won’t
cool to fast causing cracks or breaks; known as….
•Thermal Shock – The cause by a sudden shift of temperature
hot or cold causing the glass to break, crack or shatter.

15. MY FIRST COMPLETED PROJECT
This small cup was made
by using the blowon mould
to give the line pattern.
