Draping an Upside Downside Fused Glass Bowl, Glass Fusing Project, Part 2

This video is the final part of the one where we tested a technique of fusing stacked glass on both sides of a piece all at once. The first video resulted in a fused piece, though not refined.

So this project is really taking that piece and turning it into a finished piece.

The video tutorial includes the design, materials, and equipment information, as well as the cutting of glass, firing, and slumping.

Project Information

Fused Glass Drape

In the YouTube video, you will find links to related videos, a chapter list with time stamps, and links to more resources.

Don’t forget, the glass I use is Bullseye 90 COE. I use Thinfire fiber paper on the shelf, but when fire polishing on my shelf, and slumping in moulds, I spray with boron nitride mould release.

In this video the first thing I had to do was coldwork the piece. It came out of the kiln very rough, at least on the underside. I had it sitting on 3mm fibre paper and that left a rough texture. There were also a lot of little spikes around the edges that needed to be removed. As well, there were small black bits in the top of the piece. I believe from the kiln elements as I oped and closed the lid.

First thing then was to grind the edges so they were nice and square, then I sandblasted the entire piece. This cleaned it up quite well, though I was unable to remove all the black bits that had fused into the top.

This then went into the kiln for the drape. The schedule is below. A big thing here is to make sure it is sitting on the former evenly. In the video you will see me try to make sure it was centered. I would normally just measure from the former to each edge. In this video I tried someting else, but it didn’t work well. Will not be trying that again.

Anyway, I got sidetracked a little during the drape and as you will see in the video things went a little awry.

If you have any questions please ask in the comments section on YouTube.

Drape Firing Schedule

I used this schedule to flatten the piece as well.

  • #1 – 167 C ( F) up to 580 C ( F), no hold. Watch carefully as things change quickly.
  • #2 – Full down to 482 C (900 F), hold 60 minutes
  • #5 – 65 C ( 149 F) down to 425 C (797 F), no hold
  • #6 – 132 C ( 270 F) down to 371 C (700 F), no hold
