Product Details

Product Information

The Firebox 8 is a side firing kiln, with the elements in all four walls for an even firing.  The lid itself is a lightweight brick construction coated with refractory cement. It has a cool-touch handle. The chamber is also made from lightweight brick, which is used because it is able to expand and contract as the kiln heats and cools. It also helps reduce the overall weight of the kiln. The whole kiln is set on sturdy metal feet.

The kiln comes with a 2-year warranty (UK Only)

Special features:

  • Full accessory kit, including- stand, kiln shelf, 3 shelf props, kiln wash (200g) and firing paper.
  • Mini Touchscreen Controller

Energy Credentials:

  • Basic Full Fuse KwH: 1.73*
  • Average Cost of Firing: £1.87*

Please note: Due to the material used to make the lid, they are prone to crumbling or flaking. This is usually cosmetic and does not affect the kiln's performance. This type of damage can be repaired with Skutt Refractory Cement.

*Information based on supplier testing with 6mm Bullseye Glass on a Basic Full Fuse, and will vary slightly between firings. Energy prices calculated using the UK energy price cap of 27.03p per KwH, correct as of the 1st April 2025.

Highly rated glass fusing starter unit praised for ease of use and reliability. Customers said it's "incredibly easy to use" with preset programs ideal for beginners and jewelry makers. Quick cooling times improve turnaround. Main limitation is compact size, though some wish they'd purchased larger model. Consistent results with excellent support.

I got this 2weeks ago I have never done glass fusing. The videos are great they got me started. I'm making great things now. It's a great starter kiln

I bought this kiln as a tester kiln to sit alongside its big brother the Firebox14. Its a super little kiln and quicker to fire and cool, with the bonus of have the same controller.

Its given me extra capacity but more important for me, flexibility to fire at different temperatures in smaller batches in the middle of a larger firing run.



The information videos on how to change the settings are fantastic too, much easier to understand than the manual.

Its also a great peace of mind to know that the Warmglass team are available to talk to with any technical issues. I would not dream of buying a kiln from anywhere else now.



The elements in the side also give a nice even firing. Its also very sturdy but light enough to take with me when teaching residential workshops,

This is a fantastic starter kiln and I could not recommend it more highly for its ease of use, reliable results and compact size.

Thank you Warmglass

My son bought me this kiln for Christmas, up until now I had been using a microwave kiln which has obvious limitations. For jewellery makers this kiln is ideal and soooo easy to use with easy to follow instructions for beginners like me. The auto function with fast full fuse allows beginners to make lovely pieces without the worry of having to judge times by themselves while the Pro function allows the more experienced the flexibility to create their own firing times. I love this kiln which has quickly become the star of my craft room. For those who are considering buying it I would just say 'don't delay any further, order it. You'll be glad that you did.

After a lot of thinking I bought this kiln to get me started in glass rather than wait and get a bigger one. It is incredibly easy to use on the auto programmes and even accessing the pre-stored casting programme was fairly simple. It is ideal for Bullseye glass, but I haven't yet started tweaking the temperatures to get better results from float glass, which seems to end up with a strong tack fuse instead of a full fuse. The main drawback is size, but that was known about and is more than compensated for by ease of use.

This is my first kiln and I love it. I was a little concerned about it being the lowest cost kiln (you pay for what you get kinda thing) but it was the only one we could afford. Since getting it, it is permanently on, the only thing that would make me trade this kiln would be for a bigger one and even then, it would take a lot of convincing!!!

As complete novices my wife and I bought this as first kiln 12 months ago. It has been great, easy to use especially with Warm Glass's firing guides and prompt answers to email questions. We use it to fuse pendants, coasters, mirror/picture frames and slump an fuse small dishes. There are no downsides to this kiln, it does everything we want, the only BUT, wish we had bought the Firebox14 model for the extra firing space

I love this little kiln for jewellery and smaller items. I particularly love the speed with which it cools, so turnaround time is much quicker. I'd recommend it for both those new to fused glass and those with more experience.

As a glass fusing novice, I was unsure about this kiln when I first used it. I found it awkward to remove and fit the shelf without knocking the thermocouple which protrudes from the inside wall. However having taken advice from Warm Glass, I've got used to this now - and have to say it's been a great buy. The kiln is compact, but perfect for smaller pieces and jewellery. Small yes - but nice looking and it stable on its sturdy legs. It's easy to use with preset tack, slump and full fuse programmes - results are consistently good. I do recommend this as a 'pocket rocket' of a kiln for beginners - great value for the price.

My first kiln and I made the right choice. Designed with beginners in mind it fused side by side samples of System 96 and Bullseye perfectly on the auto setting. Well made, easy to operate and takes approximately 7 hours for a fully fused piece to be 'touch cool' . Liftable, albeit short distances, the base/legs do not get beyond warm whereas the steel casing and roof get too hot to touch directly. I recommend fabricating a small chicken-wire enclosure if you have inquisitive cats like me looking for a warm surface to sleep on! Speedily delivered by warm glass - thank you :x

A great kiln. My first purchase and I am very pleased with the product and the service i am a beginner and found the manual accurate and thorough. My test firing proved the auto setting is just perfect for fusing.
