I was always so pleased with my beautiful Nabertherm kiln & used it most days for 7 years until I moved house & couldn't get it through the doors. I used it for my own work & held workshops in my studio too. It never failed me. It was simple & reliable to use & a great size for an annual coaster commission I had of 100 a time! I sold it to a beginner for an excellent price. She is now very experienced another 5 years on & uses it daily in her studio. I'm now in the market again and will be choosing another nabertherm, this time I'll be going for a larger model as I'll be creating large outdoor panels. I can't fault this kiln, never had to replace a thing!

I have been using my 240 for 5 years and it's never skipped a beat or failed to produce the most perfect firing, it also still looks as good as it did when I bought it.

Whenever I have had questions about firing the people at warm glass have been spot on with their advice. Thank you warm glass

I choose the Nabertherm kiln as I wanted a professional kiln that would be reliable in it's performance. I sell my work in galleries and need to know that I will get the same perfect results on each firing. I have not been disappointed either. I was commissioned to make a large scale piece by a school and had to fire 64 glass tiles. I was not worried about firing them in my kiln and they all came out perfectly. (previously I have had devitrification on my work when using other kilns but have had no problems with my Nabertherm) The kiln is solid and well built and the internal space is large enough for most pieces. I also find the kiln extremely easy to load as it is top loading and sits on a trolley. This makes life much easier than the front loading kiln I was using previously. The kiln is also very quiet and I am happy to programme it and leave it to run over night. I also choose this kiln because of the extended guarantee that comes with it. Another factor that made me choose this kiln, was I know this is the kiln you use for firing work produced during your workshops and I knew if I had any problems setting my programmer then the team at Warm glass would be able to talk me through what to do. I am very pleased with my kiln and wouldn't hesitate to recommend it to any serious/ semi professional maker who wants to have the facility to fire their own work.

I'm so pleased with all of the firings I've done with my Naberthern. I had a pottery kiln before and now I am getting much better results with a glass kiln.

I chose the Naberthern as it looked like the best value for money and seemed to fit all my requirements.

The programming sheet you provided is really helpful and I've found it useful that you've been able to give advice on the phone when I was using the kiln for the first few firings.

I was a little daunted at first. The Skutt Hotstart (from you) had been (and still is)so super easy (I swear it reads my thoughts!). All the programmes on the Nabertherm required me to set up which scared me but with the Basic Bullseye programmes as a guide line and Simon
