Q & A
  • What is the process of gathering molten glass from the furnace?

    -The process of gathering molten glass involves using a blowpipe to plunge beneath the surface of the molten glass in a large ceramic bowl within the furnace. The glass is then spooled onto the pipe, creating a gather. This glass is extremely hot, around 2100 degrees Fahrenheit, and has a runny, gooey consistency similar to table honey.

  • What is the significance of the blowpipes used in glassblowing?

    -The blowpipes are essential tools in glassblowing, used to gather and shape the glass. The size of the blowpipe indicates the scale of the work being created. Larger blowpipes are used for bigger pieces, while smaller ones are for more delicate work. The material of the blowpipes, usually stainless steel, is important as it is a poor conductor of heat, allowing the glassblower to handle the pipe without being burned by the hot glass.

  • How does the team ensure the glass doesn't crack or break during the shaping process?

    -To prevent the glass from cracking or breaking, the team constantly monitors and maintains the temperature of the glass throughout the process. They use a reheating furnace or 'glory hole' to keep the glass hot and workable. They also allow the glass bubble to cool down to become rigid and stable before adding more layers, ensuring that the glass can support its own weight as they continue to build up the layers.

  • What is the role of the metal jacks and wooden scoop tool in glassblowing?

    -The metal jacks are versatile tools used in the glass studio for various shaping processes. The wooden scoop tool, also known as a 'block', is used to shape the center and cool the glass. These blocks are soaked in water, allowing the hot glass to ride on a thin layer of steam, which helps in forming uniform shapes in the glass material.

  • How is the clear glass used in the demonstration different from colored glass?

    -Clear glass is more challenging to work with than colored glass because it doesn't hide mistakes as effectively. Colored glass can cover up imperfections, but with clear glass, any flaws are immediately visible. The clear glass used in the demonstration is made from soda lime glass, which is the most common type of glass in the world, but specifically formulated for glassblowing to stay hotter longer.

  • What is the significance of the 'neckline' or 'jack line' in glassblowing?

    -The 'neckline' or 'jack line' is a designated breaking point created by a constriction in the glass. This area is intentionally made脆弱 so that the finished piece of glass can be separated from the blowpipe later in the process. It is a crucial part of the glassblowing process as it allows the artist to complete the piece without the attached blowpipe.

  • How does the team manage the heat of the glass during the demonstration?

    -The team manages the heat of the glass by constantly turning the glass to ensure even heating and by using a torch to focus heat on specific areas. They also use the reheating furnace to maintain the temperature of the glass, especially when working on larger or more complex pieces. The team takes short 'flashes' or quick heats to maintain the temperature and prevent the glass from cooling too quickly, which could lead to cracking or breaking.

  • What is the role of the gaffer in the glassblowing process?

    -The gaffer is the lead artist and is in charge of the entire glassblowing process. They sit at the bench and direct the team, telling assistants what is needed and when it is needed. The gaffer is responsible for the final outcome of the glass piece, ensuring that the team works together effectively and that the glass is shaped and cooled properly.

  • How is the glass cooled down after it is shaped?

    -After the glass is shaped, it is slowly cooled down in an annealing oven over the course of about 12 hours. The rate of cooling depends on the thickness of the glass; thinner glass can cool down more quickly, while thicker glass takes longer. The goal is to cool everything at an even rate to relieve internal stress and prevent the glass from cracking or breaking.

  • What happens to the cut-off scraps of glass?

    -Clear glass scraps are recycled and melted down again in the furnace to be used in future projects. However, glass that is dirty or has color in it is not recycled back into the clear glass furnace as it could contaminate the clear glass. Instead, it is ground up and used industrially, for example, as an aggregate in asphalt or for reflective material in road striping.

  • What is the inspiration behind Masahiro Saseki's glass sculptures?

    -Masahiro Saseki is inspired by organic shapes and the concept of creating these shapes with an inorganic material like glass. He often works with a Japanese aesthetic, focusing on clean, well-designed, and beautiful forms. His work sometimes involves sandblasting away clear areas of the glass to leave behind a structure of spikes or other intricate designs, giving his pieces a unique, almost coral-like appearance.

The technique requires precision, teamwork, and a deep understanding of the material's properties.
πŸ’‘Masahiro Saseki
Masahiro Saseki is a renowned glass artist and educator from Japan, who is visiting the museum to demonstrate his glassblowing techniques. He is known for his intricate designs and the incorporation of organic shapes into his work. In the video, Saseki is leading the creation of a beautiful piece of glass art, showcasing his expertise and the collaborative nature of the craft.
πŸ’‘Teamwork
In the context of glassblowing, teamwork refers to the collaborative effort of a group of artists working together to create a piece of glass art. Each team member has specific roles, such as gathering glass, blowing through the pipe, or adding design elements. The video highlights the importance of communication and coordination among team members to successfully create a large-scale glass sculpture.
πŸ’‘Thermal Stress
Thermal stress in glassblowing refers to the internal strain that can occur when different parts of the glass cool at different rates or when it is subjected to sudden temperature changes. This stress can lead to cracking or breaking of the glass. To prevent thermal stress, glass must be cooled slowly and evenly, ensuring that all parts of the glass cool down at the same rate.
πŸ’‘Annealing Oven
An annealing oven is a specialized furnace used in glassblowing to slowly cool the finished glass pieces. This controlled cooling process relieves internal stress and strain within the glass, preventing it from cracking or breaking due to thermal shock. The oven is set at a specific temperature, typically around 900-1000 degrees Fahrenheit, and the glass is cooled over a period of several hours.
πŸ’‘Spectrum Glass
Spectrum Glass, also known as Spectrum 86 or Spectrum 96, is a type of borosilicate glass known for its resistance to thermal shock and its ability to withstand high temperatures. It is favored by glass artists for its workability and is commonly used in glassblowing studios and educational facilities. In the video, the type of glass being used for the demonstration is specified as Spectrum Glass.
πŸ’‘Glory Hole
A glory hole is a reheating furnace used in glassblowing to maintain the temperature of the glass during the working process. It is essential for keeping the glass workable and pliable, especially during intricate or lengthy demonstrations where the glass needs to be kept at a high temperature for extended periods. The glory hole is used in conjunction with the blowpipe and other tools to shape and form the glass.
πŸ’‘Annealing
Annealing is the process of slowly cooling glass to relieve internal stresses that develop during the glassblowing process. This controlled cooling is crucial to prevent the glass from cracking or breaking due to thermal shock. The glass is typically placed in an annealing oven at a specific temperature and allowed to cool over a period of several hours.
πŸ’‘Spike Formation
Spike formation is a glassblowing technique where small, hollow protrusions are created on the surface of the glass. This is achieved by attaching additional bits of molten glass to the main body, which are then shaped into spikes using tools and heat. The process requires precise temperature control and skill to ensure the spikes maintain their structure and do not collapse.
πŸ’‘Glass Recycling
Glass recycling in the context of glassblowing involves the process of reusing glass scraps and cut-off pieces from the studio. Clear glass is often recycled back into the furnace to be melted and used again, while colored or contaminated glass may be processed differently. This practice is environmentally friendly and helps to reduce waste in glassblowing studios.
