Hot Out of the Kiln

December 31, 2011

There is a chill in the air and the holidays are behind us. I don’t know about you, but this is my favorite time of the year to run the kiln. Even though the kiln doesn’t really put off much heat, the thought of warm glass being created deep inside that torrid unit excites and warms my heart.

I have been having acupuncture on my arm and so far it seems to be really helping. I have had 7 sessions so far and my shoulder is showing signs of movement and popping more easily. The pain is much less and there aren’t any more sessions of stabbing pain and my hand going cold. I feel like a pin cushion, but if that is what it takes then I will continue to the end, and to think that I use to have a big dislike of needles. It is funny how things in life challenge you to overcome your fears and assist you in further growth.

The “Intermediate Glass Fusing Projects” DVD is finally complete. Creating this piece took many, many painful hours of computer time, but it is finally finished and is also live on the website.

I already have tons of items that I would like to turn into videos and books. I am thinking about doing a section on the site with short informative movies. If there is anything in particular that you would like to see, please drop me a note and let me know.

Until next month…keep it hot!

Flash Cooling

Flash cooling is a process where the glass is brought to a high temperature and then the lid of the kiln is opened to cool down the temperature to the annealing temperature. It can also be known as venting, flash venting, crash cooling, or manual venting.

Although not suggest for most firings, there is a time and place where this process can come in handy. Most of the time it is used to freeze the glass process in place, as when doing procedures such as a drop ring. Flash cooling will prevent the glass from moving and flowing further than desired.

There are pros and cons to venting the kiln after firing glass. Turning the kiln elements off until the kiln reaches the targeted anneal soak temperature is much better for the kiln. Before using this procedure, weigh the pros and cons to see if it is worth the risk.


  • Venting the kiln will speed up the cooling process, which will speed up the firing process.
  • Manual venting will stop the slumping process and freeze the glass in your desired appearance.
  • Allowing the kiln to cool on its own may not always stop the cooling process soon enough to control the glass movement.
  • Cons

  • This process is very hard on the fire bricks. Over time it can cause the bricks to crack.
  • Firing elements are sensitive to the quick change in temperature and this process can cause the pins holding the coils to work loose.
  • Crashing the kiln can cause particles and dust inside the kiln to move and get embedded in the hot glass.
  • There is a time and place for crashing the kiln, and it is not suggested to do this process on a regular basis. The cons in general outweigh the pros for most firings. Again it comes back to knowing your individual kiln and how it fires and reacts. Rely on past firing experiences when fusing and realize the pros and cons of venting the kiln.

    Reader Question


    Hi Connie: About how long should the cutting head on the Toyo pistol grip cutter last? How do I know when it is bad? Is there anything needed to maintain it? Thanks for your help




    My Responses


    Good questions...I guess it would depend on how much cutting you do and how well you take care of the cutter. Dirt and particles on the glass can dull the cutter.

    Notice the glass when you are cutting. If you find that you are scoring a broken line then the wheel could be chipped. If your scoring requires more pressure than usual, then it is dull and needs to be replaced.

    There are things you can do to keep the blade sharp not running your score off the glass and onto a hard surface, cleaning the glass before scoring, and using oil when making the scores.


    Do you have any other suggestions or hints on maintaining the glass cutter? Share your comments with our readers. Thanks!

    It seems that the topic of interest this month is the soon to be released flexi-glass fusing medium. This new product is the creation of David Alcala. It is due to hit the market sometime in January. It can be used to generate fusible paper-like glass film, transfers, decals, fusible threads and many more creative items.

    For more information on this new product, click here.

    Royal Treasure

    Royal glass is a fusible glass that has been coated with a mineral. This mineral does not melt when fused and needs to be capped with glass to retain the colors and pattern. The coating is very delicate and unlike a dichroic coating the material can be removed with water. This makes cleaning and scrubbing the glass a problem before firing. Once fired the coating becomes permanent.
