Crackle Technique

The crackle technique gives glass an intentionally irregular and fractured appearance of crackle glass.

Usually to achieve this process glass needs to be plunged into cold water and then reheated.

It would involve using a sensitive touch and heating just enough to retain the cracks.

Another way is to roll hot glass in a bed of crushed glass and the effect remains on the outside while the inside of the glass is still smooth.

This method would also involve a lot of steps and handling the hot glass.

crackle technique, crackle glass, fiber paper, confetti, frit

Not wanting to go through all that and still obtain the look, I did some research on the internet.

There is not a lot of information out there for obtain the look of crackle glass.

I had a friend who had done this process, but refused to share her knowledge with me.

So, I continued searching.

Recently another friend of mine, Alicyn was kind enough to share her process to achieve the look of crackle glass.

While continuing my research, I also found a couple of other ways to achieve this look.

The three ways discussed on this particular page will be the Fiber Paper Technique, the Confetti Technique and the Frit Technique.

Each process is extremely simple to accomplish.

Read through each of the different procedures and try them out.

Fiber Paper Technique

Materials

  • Basic Glass
  • Glass cleaner of choice
  • Glass Powder
  • Fiber Paper (1/8 inch thick)
  • Small Powder Sifter
  • Spray Bottle
  • Water
  • Kiln
  • Prepared kiln shelf
  • Directions:

    1. Choose what glass will be your bottom piece or basic glass.

    2. Clean glass and set aside.

    3. Pick a contrasting color of glass powder. This will make the cracks appear clearer on your piece.

    4. Cut a piece of fiber paper the size of your basic glass piece.

    5. Using a small powder sifter, sift your glass powder evenly onto the fiber paper.

    6. Fill the spray bottle with water.

    7. Lightly spray water onto the powder.

    8. Allow the powder to get almost dry and gently move the fiber paper around to create cracks in the powder.

    9. Place basic glass on top of the dry cracked powder.

    10. Heat piece to either a tack or full fuse inside the kiln.

    11. The powder will stick to the basic glass and give the appearance of cracked glass.

    Confetti Technique

    Materials

  • Base Glass
  • Glass cleaner of choice
  • Glass Confetti
  • Kiln
  • Prepared kiln shelf
  • Directions:

    1. Choose what glass will be your base piece of glass.

    2. Clean the glass and dry.

    3. Pick a contrasting color of glass confetti. The contracting color will enable the cracks to be more noticeable.

    4. Sprinkle the confetti onto the basic glass.

    5. Heat piece to either a tack fuse or full fuse inside the kiln.

    Frit Technique

    Materials

  • Foundation Glass
  • Glass cleaner of choice
  • Glass Frit
  • Kiln
  • Prepared kiln shelf
  • Directions:

    1. Choose a color for your foundation glass.

    2. Clean glass and place on kiln shelf.

    3. Pick a different color of glass frit. This will make the cracks stand out on your finished piece.

    4. Sprinkle frit onto the glass.

    5. Move frit around so that when the pieces melt there will be gaps.

    6. Heat entire piece to a tack or full fuse in the kiln.

    While trying each one of these methods, I have found that the fiber paper method gives the best results of a crackle technique. If you know of other process and want to share, please let me know your process for achieving a crackle technique.
