Jen-Ken · Kiln Furniture · Furniture Kits Jen-Ken Furniture Kit JK² 15" (Glass/Casting) 2 full JK² shelves · 12 posts in four heights · 1 lb shelf primer The glass and casting furniture kit Jen-Ken lists for the JK² 15". Two full JK² shelves — cut to the JK² chamber, not a generic round — twelve posts in four heights, and a pound of shelf primer. Two solid shelves rather than halves, because the JK² 15" is a glass and casting kiln and a seam under slumping glass shows in the finished piece. We carry the JK² 15" Glass/Casting Kiln.
Shelves2 full JK²
Posts12 (3 each of 1", 2", 4", 6")

Key features
Two full JK² shelvesOne-piece shelves cut for the JK² chamber. Jen-Ken calls these JK² shelves rather than a plain round — they are specific to this kiln family.
Three 1" postsThe shortest spacing — flat fusing, tiles, jewellery.
Three 2" postsLight clearance over a mould.
Three 4" postsMid-height spacing for a deeper mould or slumped form.
Three 6" postsTall spacing — casting work and taller moulds.
1 lb shelf primerShelf primer — kiln wash — goes on the shelf before the first firing so glaze cannot bond to it. One pound coats a lot of shelf.
No half shelvesJen-Ken does not include half shelves in this kit. Add them separately if you want a split level.
Posts, totalTwelve posts — three each of 1", 2", 4" and 6" — three levelling sets of four heights.
Optional accessories
Extra kiln shelvesShelves are consumables — they warp, take glaze drips and eventually crack. We sell Jen-Ken shelves individually in full, half and fiber.
Extra kiln postsPosts are sold one post at a time, in 1", 2", 4" and 6". A second set in the height you use most is the cheapest capacity you can buy.
Kiln washMore shelf primer. One pound comes in the kit; you will re-coat as it chips.
A matching Jen-Ken kilnWe stock 63 Jen-Ken kilns. If you are buying the kit and the kiln together, we will make sure the two match before anything ships.
Common questions
Which kilns does this fit?Jen-Ken lists it as the JK² 15" glass/casting furniture kit. We carry the JK² 15" Glass/Casting Kiln. We also carry a JK² 15" Glass Fusing Kiln, which is a different kiln — do not assume one kit covers both. Jen-Ken names the kiln model in the kit's title only — they publish no separate compatibility list. Send us your model number and we will confirm it.
How is this different from the JK² 22" Ceram-a-Glass kit?Size and quantity. This kit is two full JK² shelves and twelve posts at $350. The JK² 22" Ceram-a-Glass kit adds four 26" half shelves on top of the two full JK² shelves and doubles the posts to twenty-four, at $695.
What is a JK² shelf?Jen-Ken's shelf cut for the JK² chamber. It is not interchangeable with their plain round shelves. If you are replacing one, give us the model number rather than a diameter.
Does it include a mould or a kiln post set for casting?No moulds — shelves, posts and primer only. The twelve posts are a post set: three each of four heights.

Common questions about this kiln

Still stuck? Call or text (470) 264-3563 and talk it through with a real person.

Is freight delivery included in the price?

No. Kiln prices do not include freight, and we do not quietly build it into the product price. Freight is charged at a flat rate based on your delivery address and is shown at checkout. Liftgate service is included when it is needed, and standard delivery is curbside. You can estimate your delivered cost with the ZIP code tool above the Add to Cart button.

Can I return this kiln if it is not right?

Return requests can be submitted within 30 days of delivery. The kiln needs to be in its original packaging, in new and resellable condition, and approved before it is sent back. A restocking fee may apply. Completing the manufacturer's recommended first test firing does not by itself make a kiln non-returnable, so you can confirm it works before you commit. Full terms are on our Returns page.

What electrical supply do I need for this kiln?

The Specifications tab on this page lists this model's voltage, amperage, required breaker size and NEMA plug configuration. Most 240V kilns need their own dedicated circuit fitted by a licensed electrician, while many 120V models run from a standard household outlet. If you are unsure what your space can support, call or text (470) 264-3563 before ordering.

Does this kiln come with a warranty?

Yes. This kiln carries the Jen-Ken manufacturer warranty. Coverage length, what is included and any registration deadline are listed in the Specifications tab on this page. We are an authorized Jen-Ken dealer, which is a condition of warranty coverage on most kiln brands.

What comes with the kiln, and what do I need to buy separately?

The What's Included tab on this page lists exactly what ships with this kiln. Most kilns need shelves, posts and kiln wash before your first firing, and these are not always included. A vent is recommended for indoor installations. Any add-ons available for this model are shown above the Add to Cart button.
