Cygnus X-1, Destroyer of Space/Time

There’s a glass fusing shop in north Austin named Helios Glass. It’s an hour’s drive north of me, so I don’t visit very often. However this year, friend Christine persuaded me to take part in their Iron Fuser competition, in which a theme is given, and you have to use all the glass in their supplied pack in your entry. Since the theme was science based, and they included glow-in-the-dark glass in the pack, I didn’t need a lot of persuading 🙂


I made this clock, and named it ‘Cygnus X-1, Destroyer of Space/Time’. It’s about eight inches in diameter. It took many layers of glass and five separate firings.



This graphic contains the reasons and representations contained within the design.


And here is what it looks like when it glows in the dark 🙂

I used glow paint for the clock hands. They look a lot more green, which is handy when you want to pick out the hands from the other glowing dots.



I am very pleased and delighted to report that my entry won the Astronomy prize in the competition!



You can see all the entries in an online gallery, here:

I’m really pleased to have won a category. The standard of entries was very high, and I’m honored to be included amongst them. Thank you, Helios!
