Zimmerman Glass Factory / Bart and Kerry Zimmerman

395 Valley Road    Corydon, In.  47112    (812) 738-2206

Pre-Visit Learning Activities:

·        View PowerPoint presentation about traditions, time lines, tools, and safety. There are also several videos available to watch on this PowerPoint.          Zimmerman’s_Glass_Art.ppt

·        Students will watch an internet accessible video that introduces students to the art of handmade glassware.  www.neder.com/glassact/vidspinshape.html

·        Students will learn, identify and use tool vocabulary that they will see at Zimmerman’s on their visit.  Flashcards have definitions and pictures. (See attached file and list)     Zimmerman vocab cards 2.xls

·        Students will identify tools used to make glassware-especially those that will be used at Zimmerman’s.

·        Students will research the history of handmade glassware; specifically the history of Zimmerman’s.

·        Students will discuss temperature/degrees associated with glassmaking vs. daily temperatures in various settings.

·        Students will list safety factors that must be c

onsidered by glassmakers as well as spectators at Zimmerman’s.  (This should be a follow-up after video presentations)

·        Students can study the composition of glass.


During the Visit:

·        Practice Good Learning/Listening Skills:  Students will watch various glass objects being made.  Students will listen to the owners/operators share information about the history, techniques, safety precautions, and economic value of their business.  Students will have the opportunity to ask questions before, during, and after the presentation.

·        Creating Future Artists:  Students can rotate through various “art stations” set up by teachers outside of the glassmaking shop.  While a group is inside, the remainder of the students will have the opportunity to create their very own work of art to take home with them.  Materials will be available for students to create a sculpture/functional art form using modeling clay, plaster, paper mache, string, beads, glue, collage materials, tape, socks, buttons, ribbons, colored wired, empty jars, etc.  Use your imagination!  Junk found in your classroom…or somebody else’s classroom J….are little treasures.  Bring it, and allow your children to create anything they want. 

·        Creating Future Advertisers:  Students will take photos to be used later to create brochures and posters for Zimmerman’s.  Students can film the glassmaking in progress as well as peers on the fieldtrip to be used later for commercial/advertisement making.

·        Hands-On Opportunities:  Students may be allowed to assist a glassmaker in making an object (holding the rod, spinning the rod, cooling the glass or breaking the glass from the rod).  Due to the length of required cooling time, no objects can be taken home.

·        Students may have an opportunity to handle the hand-held tools used to shape glass.  Students may purchase previously made glass products.


More Fun in 
the Classroom:·       

Students will use photos taken to create a brochure for Zimmerman’s.

·        Students can use actual photos/filming taken to create a commercial/advertisement for Zimmerman’s.

·        Students will use colored tissue paper and wax paper to create a ‘stained-glass replica’ of something they saw at Zimmerman’s.

·        Students can create a sand art paperweight.

·        Students can use clay to create an art project that represents something that could be made at the glass factory.  Have students pay attention the detail and care needed to create a product using various tools and ‘kneading’ needed to ensure their clay has no air pockets, cracks, weak spots, etc.)

·        Students can play matching games with the vocabulary cards provided in the pre-visit section.

Annealer / Annealing Oven / Kneeling Oven - Oven that is used to cool the glass slowly. The annealer sits at around 900 degrees Farenheight and is brought down to room temperature overnight so that it does not crack under stress.

Batch - Raw components to be melted into Glass (Silca, Carbon, Lime…) Can be purchased through various manufacturers, however many artists prefer to mix their own batch in order to have greater control over things like purity, color and melting temperatures.


Gaffer's Bench - The bench is the center of the hot shop. 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.


Cups / Blocks - Wood molds that fit in the palm of your hand to be used to shape the glass in the early phases of the process.


Blowpipe - A hollow steel rod, with a mouth piece on one end which the artist blows through to expand a bubble through the hot glass.


Diamond Shears - To evenly cut off a bit of glass, also to be used placement of bits.


Didymium - Protective eyewear worn by glass artists have pink lenses to help cut down on the UV rays emitted by the furnace and glory hole.


Duckbill Shears - Shears with an open edges, used to trim the lip of a blown vessel.


Furnace - Oven that holds liquid glass. Usually able to be opened and closed as more glass is needed. Sits around 2200 degrees farenheight.


Glory Hole / Reheating Furnace - Oven that is used to reheat glass as it is being worked. Usually the front is open for easy access during the working of a piece. Sits around 2200 degrees farenheight.


Heat Shield - Using a paddle or something similar placed in between the working artist and the glass, providing a barrier that the heat will not penetrate.


Jacks - Large tongs that are used in order to create score lines in the neck of a piece. It is the main tool used by glassblowers and can be used to perform a variety of tasks.


Kevlar Gloves - High heat resistant gloves or big mittens that are used to carry the glass from the knock off table to the annealer.


Knock Off Table - A table that the artist uses as a rest for a piece prior to putting it in the annealer. The table is usually lined with Fiber Frax.


Marver - A steel (or marble) table that is used to shape the glass. The artist can roll the glass on this table to achieve a variety of goals, most of which have to do with shape.


Optic Mold - A steel or bronze mold that puts ridges or other shapes into the vessel, Optic Molds are used early in the process.


Paddle - A wooden tool used to flatten the bottom of a piece.


Punty - A solid steel rod that is used for bits and for the transfer process of the piece from on the blowpipe to the "punty".


Steam Stick - A cone shaped piece of wood and is used in place of a soffietta, instead of blowing the steam stick uses the water soaked into the wood to creat steam which can push the glass out.


Wax - Bees Wax and or Carnuba wax is used to coat the jacks so that they don't stick to the glass.


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.

Without Pictures

Assistant - The Person (or People) helping the Gaffer make a piece.

Maestro - An Italian glass master.


Neck - The edge of the piece that will be scored and separated when transferring the working piece onto the punty.
