|the paragon km18 knife-making furnace||here are links for the on-line shop and all the other kilns|
The Paragon KM18 is a 1290°C, rectangular, plug-in, front-opening, table-top, firebrick kiln, with a ramp-hold Sentry Xpress 3-key digital programmer. Choose Paragon black or customised berry, blue, jade, navy, pink, purple, or turquoise.
The UK-EU kiln is rated at 230V-240V 2000W, so can use a regular mains socket. It's fitted with a switch that cuts off power to the elements when the kiln is opened: a legal safety requirement. However, never get careless: kilns are very hot and connected to the mains.
The external dimensions are 432mm x 787mm x 432mm high. The case has slots for air circulation and an integral stand with four rubber feet. The standard drop-down door is hinged at the bottom and kept closed by a stay-cool counterbalanced handle: although you can choose a side-hinged door. The shipping weight, including the crate, is about 84kg.
The firing chamber measures 140mm x 457mm x 108mm high and heats from both sides with the elements in dropped recessed grooves in the 76mm thick bricks. The kiln has a silent long-life solid-state electronic relay mounted on an aluminium heat-sink and a long-life nickel-chromium K-type thermocouple.
The programmer's electronic display prompts for heating rates, target temperatures, hold times, and cooling rates, making it easy to set up and re-use accurate heating, holding, and cooling sequences. An optional cone-fire mode, up to cone 10, will simplify any work with ceramics.
The options, upgrades, and accessories for this kiln are in the on-line shop:

|EXTRACTS FROM REVIEWS, AND MY OPINION|
The KM18 is a robust, practical, high-temperature, fully-programmable kiln, ideal for a blade workshop making camping, hunting, kitchen, and pocket knives; an engineering facility annealing, hardening, heat-treating, and tempering blades, cutters, dies, tools, and metal parts; or a creative studio making architectural features or artwork components. And you can work with ceramics and glass within the kiln's size limits.
The internal height is just right for blades resting on their holders. A larger kiln might not have the same uniformity of temperature along the blade and would be energy-wasteful: so less precise and higher production costs.
The kiln has a Sentry Xpress 3-key digital programmer. Its features include twenty-five free-to-set sequences, each one with up to twenty segments.
You can upgrade to an enhanced Sentry 12-key. Its features include thirty-five free-to-set sequences, each one with up to twenty segments, and automatic control over hardware options: an electric kiln vent, a gas injection system, and a USB computer interface.
Or an advanced touch-screen Sentinel Smart Touch. Its features include those of the Sentry 12-key and real time displays of voltage and current, a novice mode with prompts, firing sequences presented graphically, and wifi connectivity and updates: so a functional upgrade not just a design preference.
The standard drop-down door is hinged at the bottom and kept closed by a stay-cool counterbalanced handle. The internal safety switch is activated by the hinge.
The optional side-hinged door has a lever door-latch and an external safety-switch box mounted above the hinge: not such a tidy design.
Just be sure that 457mm is deep enough and that one of the KM24 series might be better: a KM24, a KM24 XL or, for precision work, a three-zone KM24 PRO or a three-zone KM24 XL PRO. To learn more about other kilns, use the link above the menu bar near the top of the page.
There are other kilns in the KM series, summarised below. To look at these, other kilns, the price list, or shop on line, use the links at the top of the page.
There are five standard versions, 140mm wide internally: the KM14, KM18, KM24, KM36, and KM45 with drop-down doors, firebrick interiors, and Sentry Xpress 3-Key programmers.
There are five standard XL versions, 279mm wide internally: the KM9 XL, KM14 XL, KM18 XL, KM24 XL, and KM36 XL with drop-down doors, firebrick interiors, solid-state relays, and Sentry 12-Key programmers.
There are five PRO versions, 165mm wide internally: the KM9 PRO, KM14 PRO, KM18 PRO, KM24 PRO, and KM36 PRO with stainless-steel spring-assisted guillotine doors, rigidised ceramic-fibre interiors, fast-heat embedded elements, solid-state relays, zoned temperature control, and touch-screen Sentinel SmartTouch programmers.
There are six XL PRO versions, 337mm wide internally: the KM9 XL PRO, KM14 XL PRO, KM18 XL PRO, KM24 XL PRO, KM36 XL PRO, and KM45 XL PRO with stainless-steel spring-assisted guillotine doors, rigidised ceramic-fibre interiors, fast-heat embedded elements, solid-state relays, zoned temperature control, and touch-screen Sentinel SmartTouch programmers.
Finally, a quote from a user: Nothing compares with the control that I have with my 3-zone KM PRO. “I know the temperatures of all three zones at the same time and I know that the back of the kiln is the same temperature as the front. I can download the program and see what happened in a firing and just make sure everything was consistent. And I know that my next knife is going to be as good as my last knife.
