Preparation and Safety Guidelines

Tools Needed
  • Glass
  • Torch
  • Pipe
  • Marvering Table
  • Optic Mold
  • Graphite Stick
  • Blow Hose (optional)
Safety Guidelines
  • Always use safety glasses when working with glass. Shattered glass can cause serious eye injuries.
  • Work in a well-ventilated area. Glass cutting and grinding can produce dust that is harmful if inhaled.
  • Use caution when handling sharp glass edges. Wear gloves to protect your hands and be mindful of where you place cut pieces to prevent accidental cuts.

Step-by-Step Instructions

  1. Prepare the Base

    • Gather white glass and roll it twice for a white backing. This makes subsequent colors pop.
    • Reheat, melt the glass, and marver most of it off the pipe. This leaves a gathered color on the pipe.

  2. Create the Initial Bubble

    • Heat the glass and create a starter bubble (doesn't need to be large). If the color is opaque, watch for the expansion of the sides to know when to stop blowing.

  3. Add Orange Color

    • Gather your chosen color (in this case, orange). Be careful not to press too hard; tap and turn to gather.
    • Reheat and potentially roll the color again. The white backing will make the transparent color stand out.
    • Marver the glass off the pipe to cool and melt the frit, ensuring a smooth texture.

  4. Shape the Pumpkin Body

    • Heat the glass, supporting the weight to avoid crushing the starter bubble.
    • apply upward pressure (towards the ceiling), avoiding lateral movement. Fast turns create even heat distribution.
    • Add air, ensuring a slightly larger starter bubble. Shape the glass on the marvering table to fit the optic mold.
    • Heat the glass and place it into the optic mold. Blow, cap, and compress slightly to force the glass into the ridges.

    Shape the Pumpkin Body
    • Marver the back end to push the ridges away from the pipe. Cool the bottom to help maintain shape.
    • Use the back of the jacks to cool the bottom, aiming for the jack line while blowing and expanding the glass. Consider using a blow hose for assistance.
    • Pull the pumpkin away from the mold to create a round, squat shape. Continue cooling the bottom with the jacks.
    • Use a paddle to push and create an indent at the top, resembling a pumpkin. Ensure the glass is cool enough to prevent sticking to the mold.

  5. Create and Attach the Stem

    • Create the stem with 1-2 gathers of green glass on a half-inch pipe. Roll the glass twice in color and let the pumpkin cool before removing it.
    • Heat the stem and place it in the optic mold to stretch and shape. Avoid pressing too hard.
    • Connect the stem to the pumpkin. Use a graphite stick to create coils for the stem, ensuring the cut end is handled carefully (potentially needing a torch).

Tips

  • A white backing makes subsequent colors more vibrant.
  • When gathering color, tap and turn instead of pressing hard.
  • Support the weight of the glass during marvering to avoid crushing the starter bubble.
  • For blocking, apply upward pressure only; fast turns create even heating.
  • Ensure the glass is cool enough before using the paddle to avoid sticking.

Common Mistakes to Avoid

1. Uneven Glass Cutting

Reason: Inconsistent pressure or a shaky hand while scoring the glass can lead to jagged edges and an imperfect pumpkin shape.
Solution: Use a steady hand and consistent pressure when scoring, and consider using a glass cutter with a scoring wheel for more precise cuts.

2. Cracked or Broken Glass

Reason: Applying too much force during cutting or bending the glass, especially thicker pieces, can cause it to crack or break.
Solution: Use a sharp glass cutter, score deeply, and apply gentle, even pressure while breaking the glass.

3. Poor Glue Adhesion

Reason: Using an inappropriate adhesive or not properly cleaning the glass surfaces before gluing can result in weak or failing seams.
Solution: Use a strong adhesive specifically designed for glass and ensure all surfaces are thoroughly clean and dry before applying glue.

FAQs

What kind of glass is best for making a glass pumpkin?
Clear glass jars or bottles with a relatively smooth, round shape work best. Avoid glass with sharp edges or intricate designs that might be difficult to shape. The thickness of the glass is also important; thicker glass is generally easier to work with and less prone to cracking.
What if my glass pumpkin cracks during the process?
Safety first! If your glass cracks, stop immediately. Do not attempt to continue working with cracked glass. Remember to always wear safety glasses and work in a well-ventilated area. You might need to start over with a new glass piece.
