About

I’m a stained glass crafts hobbyist. You could also say I’m a technician rather than an artist.

Occasionally I have to attend craft fairs to sell what I’ve been making. I have to sell most of what I make because there aren’t enough windows in my house to accommodate all my creations and not enough friends and family who can cope with endless birthday and Christmas presents of nothing but stained glass.

My hobby is out of control. There’s so much glass and equipment in my dining room that I must admit it is now a workshop.

I learned the basics of copper-foiled Tiffany style work and how to produce traditional leaded lights many years ago, beginning with an introductory adult education course, but only recently have I discovered the joy of messing about with a microwave kiln.

I enjoy the beauty of mathematics so,  though you might not realise it when you see what I’ve made, there’s often a mathematical aspect to its design or construction.

I have a keen interest in science but it rarely reveals itself in the design of what I make. It does however influence how I make what I make. My interest in science links to an enquiring mind that does not assume that what I am told is correct. I habitually ‘experiment’ to check the advice or guidance I have been given.

You will, from time to time, encounter the results of my experiments in this blog. Sometimes they will be silly little discoveries that are barely worth sharing. Sometimes they will challenge what you have read elsewhere. Either way, I hope you’ll find some of them useful.

    Hello,
    I just came across your site last night. I want to read everything on here. You have excellent information. I am most intrigued by your February 13, 2014 post called Liquid Stringer. I want to experiment with CMC myself. I first came across the idea of flexible wafers through the Fusion Quarters videos. With their product, Flexi-glass, they use a reusable transfer sheet. In your experience, what kind of heat resistant film do you use in this application? Thank you.

      Hi Angie. Thank you for your kind and encouraging words. I haven’t used Flexi-glass so encourage you to experiment. CMC will be a good starting point as it will form the gel to bind everything together into a sheet. As this will be weak it needs more ingredients to form a stronger structure. The MSDS file mentions phosphated polyester (to strengthen?) and PVA (to solidify?). Also mentioned are glycol ether and ethanol which both evaporate quickly, so help it set more quickly. Finally, try an acetate sheet (used for old-fashioned OHP projections) as the backing sheet on which you create your masterpiece but I would not put the backing sheet in the kiln! Good luck in your experiments.

  2. Hi Chatterglass!

    I am working in a huge lpg gas fired kiln in remote victorian bushand and have repeatedly fired my kiln up to full fuse with an extra conservative tempering schedule and it just keeps cracking! at a loss to what to do and wondered if you had come across anyone working in bullseye that is not on electric that will chat rather than refer me to endless streams of notes in Farenheit I simply cant work out. Your blog answered so many confusions for me but still I dont know what to do!

      If the glass keeps cracking then you need to re-consider the anneal hold time you use, the rate at which the kiln is being cooled over the anealing temperature range and also the rate at which the final cooling occurs. This is particularly important for large pieces of glass and for pieces of glass that have unusual shapes. Glass is very sensitive to sudden temperature changes, particularly when not fully annealed, explaining why we generally use an electric kiln with a computer controller. The nature of the cracks may give you clues about what is going wrong.
