My Father's favourite colour!
I achieved this gradation by overlaying two shades of concentrated glass colour over one another. I enjoy watching the different textures and patterns that the silver foil creates as it disperses while the glass is inflated.
One interesting thing about working with hot glass is that the colour always looks different while it is hot than it will look at room temperature. With certain colours you can roughly tell what it will look like cold, but others look completely different when they are around 600 degrees celcius and up. I think this phenomenon is more common when working with opaque glass. This particular vase looked bluer on the blowpipe, but not drastically so.
While I'm on the topic of colour, I would like to mention that I listened to an interesting documentary about Synesthesia on the radio tonight. I had never heard of this condition before, but it was fascinating to learn about it! You can listen to the program here.
