The fifteen inches of height is the real reason to buy this over the 11-inch JK²: a deep sink mould or a tall draping form goes in standing up rather than not at all. It fires top and side together for an even fuse across a shelf that wide, ships with lid lifters and Jen-Ken's 12-button controller, and runs on a 240V 45-amp circuit.

Their page gives the breaker as \"50A or 60A\" on a NEMA 6-50R receptacle — but a 6-50R is a 50-amp device, so it cannot sit on a 60-amp circuit. The wiring table in Jen-Ken's own owner's manual gives the glass JK² a 50-amp fuse on that receptacle, which is the half of the range that can actually be built. We will not print a range where the other half is unbuildable, because the breaker size is one of the two figures you hand your electrician. Call or email us before anything is wired and we will get the nameplate figure from the factory for your build.\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"d-faq-item\"\u003e\n\u003cspan class=\"d-q\"\u003eWhat is safe to rely on?\u003c\/span\u003e\u003cspan class=\"d-a\"\u003e240V single phase, a 45-amp draw and 10,800 watts — the arithmetic confirms it, since 240V × 45A is exactly 10,800W — on a NEMA 6-50R receptacle with #6 copper. Those appear consistently across Jen-Ken's sources and are published above. #6 copper carries 65 amps at 75°C, so it is sized for anything the breaker question resolves to. Jen-Ken's manual adds one caveat worth knowing: a run of more than about 30 feet from the panel may need the next heavier gauge.\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"d-faq-item\"\u003e\n\u003cspan class=\"d-q\"\u003eHow is this different from the JK² 11\"?\u003c\/span\u003e\u003cspan class=\"d-a\"\u003eHeight, and the current that comes with it.

Buy this one if you slump sinks, stand deep moulds up, or want to stack two shelves; buy the 11-inch if your work is flat and you would rather have the smaller circuit and the lower price.\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"d-faq-item\"\u003e\n\u003cspan class=\"d-q\"\u003eAnd how is it different from the JK² 15\" Glass\/Casting?\u003c\/span\u003e\u003cspan class=\"d-a\"\u003eThis is the plain fusing and slumping build: top and side elements together, rated 1,700°F. The Glass\/Casting version is the same chamber and the same six cubic feet but adds a side-only firing mode and a 2,150°F ceiling, which is what casting moulds and low-fire clay need. Same box, two different kilns — if you only fuse and slump, this is the one to buy.\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"d-faq-item\"\u003e\n\u003cspan class=\"d-q\"\u003eWhy square rather than round?\u003c\/span\u003e\u003cspan class=\"d-a\"\u003eBecause most glass work is not round. Square shelf area is what you actually use when you are laying out rectangular panels, square tiles or a set of four plates, and a round chamber gives those corners away. Square shelves are also cheaper to replace and easier to cut fibre paper for.\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"d-faq-item\"\u003e\n\u003cspan class=\"d-q\"\u003eWhat cone will it reach?\u003c\/span\u003e\u003cspan class=\"d-a\"\u003eJen-Ken publishes no cone rating for any kiln in their glass line, and we have not invented one. What is published is the maximum temperature, which is in the table above. Cone numbers are a ceramics measure; for glass work the temperature and the firing schedule are what matter.\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"d-faq-item\"\u003e\n\u003cspan class=\"d-q\"\u003eHow long until it ships?\u003c\/span\u003e\u003cspan class=\"d-a\"\u003eJen-Ken builds to order in Lakeland, Florida.
