Preparation and Safety Guidelines

Tools Needed
  • Furnace
  • Blowpipe
  • Jacks
  • Cherry wood block
  • Cherry wood paddle
  • Tweezers
  • Newspaper
  • Water
  • Soffietta
  • Wrap
Safety Guidelines
  • Always use safety glasses when working with glass or sharp tools. Glass can shatter unexpectedly.
  • Ensure the sealant you use is aquarium-safe and completely cured before adding water and fish. Toxic fumes can harm your fish.
  • Avoid using excessively hot water or placing the bowl near a heat source, as sudden temperature changes can cause the glass to crack.

Step-by-Step Instructions

  1. Gathering and Initial Shaping

    • Gather a small amount of glass onto the blowpipe, constantly turning to prevent it from falling off.
    • Roll and smooth the gathered glass, allowing it to settle. Trap air inside to create a bubble, then smooth it out.

  2. Adding and Shaping the Body

    • Add more glass using the jacks, shaping and cooling specific areas to create a hard edge.
    • Use a cherry wood block (soaked in water) to shape the piece symmetrically before blowing it out. This ensures even expansion.
    • Blow out the bubble to increase its size, ensuring uniformity. Let it cool before adding more glass.
    • Focus on shaping the bottom two-thirds, keeping the top cool to control expansion. The bottom should be thick for stability.

  3. Final Shaping and Bottom Creation

    • Add the final gather of glass, ensuring the piece is cool to prevent bubble collapse.
    • Use the cherry wood block and paddle to maintain symmetry and create a flat bottom.
    • Use jacks and a paddle to shape the bottom edge and make it flat.

  4. Expansion and Separation Prep

    • Heat the piece and blow it out further, controlling the expansion with damp newspaper and a helper (Phil) providing air.
    • Create a constriction at the top of the piece using jacks to facilitate clean separation from the blowpipe later.

  5. Separation from Blowpipe

    • Create the “punny” (a bridge) to separate the piece from the blowpipe.
    • Carefully break the piece off the pipe using water to shock the connection and a paddle to apply force.

  6. Finishing and Lip Shaping

    • Use a soffietta and damp newspaper to evenly open and shape the top lip.
    • Apply final touch-ups to the lip, ensuring even heat distribution throughout the piece to prevent breakage.

Tips

  • Maintain symmetry throughout the process for a uniform shape.
  • Use a helper for larger pieces to control both heat and shaping simultaneously.
  • Ensure the bottom of the piece is thick and sturdy for stability.
  • Keep the newspaper consistently damp to prevent burning, but avoid excessive water to control heat.
  • Avoid reheating the top of the piece once the constriction is in place.

Common Mistakes to Avoid

1. Uneven Glass Cutting

Reason: Improper scoring or applying too much pressure during the cutting process leads to jagged edges and an overall unprofessional look.
Solution: Practice scoring the glass firmly and evenly, then carefully snap it along the score line using pliers.

2. Insufficient Sealing

Reason: Improper sealing techniques (e.g., inadequate silicone application or air bubbles) can lead to leaks and water damage.
Solution: Apply a generous, even bead of silicone sealant, ensuring no air pockets are trapped, and allow sufficient drying time before adding water.

3. Ignoring Safety Precautions

Reason: Working with glass without proper safety gear (e.g., gloves and safety glasses) can result in cuts and injuries.
Solution: Always wear safety glasses and gloves when cutting and handling glass.

FAQs

What kind of glass container can I use for my DIY fish bowl?
Use a sturdy, clear glass container without any cracks or chips. Avoid using recycled jars that may contain harmful residues. Ideally, choose a container specifically designed for holding liquids, like a large glass vase or a repurposed aquarium.
How do I ensure my DIY fish bowl is properly sealed and watertight?
Silicone sealant designed for aquariums is essential. Apply a generous, even bead along all the seams and edges where the materials meet. Allow the sealant to fully cure according to the manufacturer's instructions before adding water and fish.
What kind of fish are suitable for a small DIY fish bowl?
Avoid fish that require large spaces to thrive. Smaller species like Betta fish (Siamese fighting fish – but only one!) or small shrimp are generally good choices for smaller DIY setups. Always research the specific needs of any fish before bringing them home.
