Glaskolben Blown Bulb Workshop
Ages: 16+
$100 for 5 bulb tubes
Instructor: Frank Andreae
Join us for a fun experience working with blowing glass – without a furnace!
Glaskolben uses pre-blown clear glass tubes with a blow pipe end that you can fill with colored glass frit, heat over a torch flame, and blow to create an ornament or a self watering plant bulb.
The workshop will discuss different types of glass, safety practices and a demonstration of the Glaskolben technique. This includes adding the colored frit, slowly heating the tube over a flame to soften the glass, and blowing to expand the bulb.
Bring your powerful lungs since the glass does not stay hot for long. A quick, strong exhale from the diaphragm will inflate the bulb, but hesitation will allow it to cool.
You will have five tubes at your disposal to create different bulbs. The first one or two are usually practice bulbs until you get the “feel” of the warmed glass to make a better bulb. Expect to get 2-3 completed bulbs. Typical bulb is 2”-2.5” in diameter.
If you want your bulb turned into an ornament, we will cut off the blow tube and add a cap and hanger.
For beginners or experienced alike! All equipment and supplies are included.
This workshop is a pre-paid type. Choose number of people and fill out the “Get Tickets” information for payment.
