Updated October 2026 · By the Peach State Pottery team
Here is a thing that happens more often than it should. Somebody waits twelve weeks for a kiln. The freight truck arrives, the liftgate comes down, the crate gets opened, the electrician has already been and gone — and they still can't fire anything, because there is nothing inside the kiln to set the work on.
A kiln does not come with shelves. Almost nobody tells you that before you buy one, and it is the single most common reason a new kiln sits cold for another week.
That gap is what our Ready-to-Fire kits exist to close: one box, matched to your exact kiln, holding everything you need to load the kiln and run the first firing the day it lands.
Quick picks
The short answer:
- Buying a kiln from us? Add the Ready-to-Fire kit for your model at the same time. It arrives with the kiln and you fire on day one instead of day ten.
- Already own a kiln and firing fine? You don't need one. You already bought the furniture. What you may want is the Emergency Parts Kit — different product, different job.
- Not sure which kit fits? Your model number is on the data plate on the control box. Tell us the model and we'll tell you the kit — or call and we'll do it on the phone in a minute.
- What's in it: the shelves and posts sized for your chamber, kiln wash, a 30-piece assorted stilt set, heavy-duty insulated gloves, and a spare peephole plug. Vent system optional.
- What's not in it: clay, glaze and pyrometric cones. There are good reasons for all three — see below, because the cone one surprises people.
Ready-to-Fire kits launch on the Olympic range first. If you fire Evenheat, Paragon, Cress, Jen-Ken or HotShot, the individual furniture kits are already on the site and we'll build you the same bundle by phone today.
Why your kiln arrives without shelves
It isn't an oversight or a cost-cutting trick. It's that furniture is genuinely a per-potter decision in a way the kiln isn't.
Two people can buy the identical 23-inch kiln and need completely different furniture. One throws mugs and wants five shelves and short posts, stacking the chamber densely in thin layers. The other makes tall vases and wants two shelves and 8-inch posts. If the manufacturer bundled one fixed set, half of all buyers would pay for shelves they'd never use and immediately buy the ones they actually needed.
So every brand we carry sells furniture separately. Our own product pages say so plainly — the Olympic 1823HE page, for instance, lists under what is not included: "No kiln furniture either, since every line has its own separately priced furniture kit."
That's consistent across the catalog. No Evenheat kiln and no Paragon kiln ships a furniture kit. The only free furniture anywhere in either brand is a single quarter-inch ceramic fiber shelf that comes with the Paragon SC2, SC2 Pro and SC3 — small jewelry and glass kilns, and one thin shelf is a genuinely useful inclusion at that size. Everywhere else, the crate holds a kiln and no shelves.
What does ship with an Olympic kiln, so you know where the line falls: the brick sections with elements already set and wired, the controller fitted and wired, one thermocouple, the metal stand, observation plugs, the manual, and the cord and plug or direct-wire connection set by your build. That's a complete, working kiln. It just has an empty chamber.
What's in a Ready-to-Fire kit, and why each piece is there
The furniture kit for your exact chamber
This is the bulk of it, and it's the part you cannot improvise. Shelves and posts sized to the chamber, plus a bag of kiln wash. On the Olympic 18-inch kits, for example, the post count is specific: six each of 4-inch, 6-inch, 8-inch and 10-inch large square posts — 24 posts in total, which is more than people expect and is why we spell it out on the product page rather than saying "assorted posts."
Posts in four heights is the point. It's what lets you build three tight layers for mugs this week and two tall ones for vases next week out of the same kit.
Kiln wash
Kiln wash is the barrier between a glaze run and a ruined shelf. A shelf costs real money; a bag of wash costs almost nothing and saves it. Furniture kits include a 1 lb bag, which is enough to coat your shelves once. The Ready-to-Fire kit adds a 5 lb bag on top, because you will re-coat, and the usual way people discover they're out of kiln wash is at 9pm the night before a firing.
A 30-piece assorted stilt kit
The first glaze firing is where new potters lose work. Glazed ware cannot touch the shelf — the glaze melts, fuses the piece to the shelf, and taking it off takes a chunk of both with it. Stilts hold glazed work up on points so small that the marks grind off. Thirty assorted stilts covers the range of sizes you'll actually encounter.
This is the component most likely to be missing from a kiln order placed without a kit, and it's the one whose absence costs you a kiln load of finished work rather than an inconvenience.
Heavy-duty insulated gloves
For unloading a warm kiln, handling hot shelves, and the moments where you need to reach in before the chamber is fully down to room temperature. Not optional equipment in a working studio.
A spare peephole plug
The small one, and the one that makes the kit feel like it was assembled by someone who uses kilns. Peephole plugs ship with the kiln, and they are the first part people lose — they get pulled out hot, set down somewhere, and never seen again. Interestingly, Olympic publishes no plug count for any model in its manuals or on its site, so even we won't print a number for how many you'll have. We'll confirm yours with the factory if you ask. Either way, having one spare in the box is cheap insurance against firing with an open peephole.
Optional: a vent system
Available as a second variant rather than a separate hunt. Venting deserves its own discussion and it isn't strictly required to fire, which is why it's an option and not a default. If you're firing in an attached garage, a basement or any room you also breathe in, raise it with us.
What's deliberately not included
Three things, and we'd rather explain them than let you find out by opening the box.
Clay and glaze
Both are matters of taste, both come in dozens of varieties, and both must match the cone you intend to fire. Bundling a clay body you didn't choose would be a worse product, not a better one.
Pyrometric cones
This is the one worth reading. Every kiln we'd sell a Ready-to-Fire kit for has an electronic controller. A digital controller fires to a programmed schedule and shuts itself off — so nothing about running your kiln requires a cone. The old practice of propping a bending cone in a Kiln-Sitter belongs to kilns without controllers.
The honest caveat, which we'd rather give you than have you learn later: witness cones are still standard practice for verifying heatwork. A controller reports what its thermocouple tells it, and thermocouples drift as they age. Setting a witness cone on the shelf shows you what the kiln actually did, as opposed to what it thinks it did. That matters most when you're dialling in a new clay body or chasing a glaze that isn't coming out right.
So: not needed to fire, worth having once you're troubleshooting. We'll help you pick them when you get to that point.
Electrical hookup
A kiln is not a plug-in appliance, with the narrow exception of a few small 120V models. Most need a dedicated circuit, a correctly sized breaker and in many cases a direct-wired connection — work for a licensed electrician, sized to your specific model. Nothing in a box can substitute for that, and we'd be doing you harm by implying otherwise. Our 120V kiln guide covers the models that genuinely do plug in.
Why the kit has to match your kiln — the part that isn't obvious
You would think a shelf is a shelf. Buy a big one, cut it down, done. Kiln shelves are brittle refractory slabs; you do not cut them down, and the geometry is unforgiving in ways that surprise people.
Three real examples from our own fitment work, because they illustrate the problem better than a general warning:
Round chambers aren't round
Olympic's 18-inch kilns take an octagon shelf set — 15.5" × 16.5" octagons that seat against the flats of the brick. The 189 Slider is also an 18-inch kiln, also "round" in casual description, and it takes a different octagon kit again. Meanwhile our 18-inch square glass kit has 16" × 16" square shelves. Those square shelves will not seat in an octagon chamber. Same nominal width, incompatible furniture.
Two kilns with near-identical names take different shelves
The Olympic Champ is round inside: 14.5" wide. The Champ XL is square inside: 14.5" × 14.5", and Olympic's own copy explains the square design is the point, since it fits larger flat pieces. One letter of difference in the model name, and a different shelf shape. We caught this one in our own data before it reached a customer — the obvious mapping was wrong.
Shelf thickness changes with brick thickness
Olympic's 23-inch and 23H-inch kits look interchangeable on a spec sheet. They aren't: the 23H shelves are 1 inch thick and the 23-inch shelves aren't, and the two kits differ by 35 lb of freight. The "H" models have 3-inch brick and a correspondingly different chamber. Order on the number alone and you get shelves that don't suit the kiln.
Conversely — and this is the happy case — Olympic's 18-inch and 18H-inch kilns take one kit between them, covering ten different models across both brick thicknesses. There's no rule you can derive from the model number. You have to know the range.
That's the actual argument for buying a matched kit rather than assembling furniture yourself: not that it's cheaper or quicker, but that getting it wrong means a freight return on a 60 lb pallet of shelves that don't fit.
Which kit fits which kiln
The kits are organised by chamber, not by model, because one furniture set legitimately covers several models that share a chamber width. Find your model and you have your kit.
| Kit | Olympic models it covers |
|---|---|
| HotBox / HB64 | HB64E, HotBox E |
| HB84 / 86 / 89 | HB84E, HB86E, HB89E |
| Doll / Test | Doll E, Test E |
| 12" round | 129E, 1214-120E, 1214-120HE |
| 1414HE | 1414HE |
| 14" square † | Champ XL, 149GFE, Square 146GFE |
| Traveler | Traveler 120 |
| 18" / 18H" | 1818E, 1818HE, 1823HE, 1827E, 1827HE, MAS1818HE, MAS1823HE, DM1818HE, DM1823HE |
| 23H" | 2318HE, 2323HE, 2327HE, 2331HE, MAS2323HE, MAS2327HE, DM2318HE, DM2323HE, DM2327HE |
| 28H" | 2823HE, 2827HE, 2831HE, MAS2823HE, MAS2827HE, DM2818HE, DM2827HE |
| 20" / 20H" oval | 2018HE, 2023HE, 2027HE, DM2023HE |
| 25H" oval | 2518HE, 2523HE, 2527HE |
| 30H" oval | DM3023HE |
| Front-loading | 139FLE, 1818FLE |
| TopHat | TopHat 189E, TopHat 2314E, TopHat 2814E |
| Raku | 1214E Raku, 23" Raku gas |
| Gas updraft † | 2327G, 2827G, 2831G |
† These two groups are matched on chamber dimensions rather than a published model list, because Olympic names its 14-inch square and gas updraft kits by chamber width rather than by model. The fit is sound and we confirm it on the order before anything ships.
A handful of models sit slightly outside these groups and we confirm those individually rather than guess — the 1814HE, DM2523HE, DM3018HE, 2827E and TopHat 2827E among them. If yours is on that list, call us and we'll settle it before anything ships. We'd rather spend a phone call than send you the wrong pallet.
Olympic's Large Capacity front-loaders and gas kilns — the FL and DD series — aren't part of the first release. Those chambers are built to order and their furniture is specified per kiln, so we quote them individually.
Ready-to-Fire vs Emergency Parts Kit
We sell two kits and they are frequently confused, so here is the distinction in one line:
The Ready-to-Fire kit gets you firing. The Emergency Parts Kit keeps you firing.
| Ready-to-Fire Kit | Emergency Parts Kit (EPK) | |
|---|---|---|
| Buy it | With the kiln | Any time before you need it |
| Contains | Shelves, posts, kiln wash, stilts, gloves, spare plug | Spare elements, relays, thermocouple and the electrical parts that fail |
| Solves | "My kiln arrived and I can't load it" | "My kiln stopped reaching temperature and I have a deadline" |
| Matched by | Chamber size — one kit covers several models | Your exact model, since element and relay counts differ |
| Needed to fire? | Yes | No — until the day it is |
Elements are a wear item. They oxidise every time you fire, faster the hotter you go, and they fail eventually on every kiln ever made. The EPK exists because the gap between "element failed" and "replacement element arrives" is where a production studio loses a month. It is deliberately not in the Ready-to-Fire kit, because bundling spare elements into a day-one kit would mean charging every new potter for parts they won't need for years.
FAQ
Do kilns come with shelves?
No. Every brand we carry — Olympic, Evenheat, Paragon, Cress, Jen-Ken and HotShot — sells kiln furniture separately from the kiln. The only exception in the whole catalog is a single quarter-inch ceramic fiber shelf included with the Paragon SC2, SC2 Pro and SC3. Your kiln arrives complete and working, with an empty chamber.
What do I actually need to fire a kiln for the first time?
Shelves and posts sized to your chamber, kiln wash on the shelves, stilts for anything glazed, gloves, and a correctly installed electrical circuit. Clay and glaze rated for the cone you're firing. That's it — your controller handles the firing schedule.
Can I just buy a couple of shelves instead of a whole kit?
You can, and we'll sell them to you. The reason most people don't is posts: you need several heights to stack usefully, and buying them piecemeal usually costs more than the kit and takes three orders to get right. If you have specific needs — all tall work, say — call us and we'll build a custom set instead of selling you a kit with shelves you won't use.
How do I know which kit fits my kiln?
Your model number is on the data plate on the control box. Match it to the table above, or send it to us. Don't order on chamber width alone — as the 23" versus 23H" case shows, the same nominal width can take different shelves.
Does the kit include a vent?
Only if you choose the variant with one. Venting isn't required to fire, so it's an option rather than a default — but if your kiln is going anywhere you also spend time breathing, talk to us about it.
Why aren't cones included?
Because your kiln fires on a digital controller and doesn't need them to run. Witness cones remain good practice for confirming what the kiln actually did, since thermocouples drift with age — but that's troubleshooting, not setup. We'll point you at the right cones when you need them.
Will a Ready-to-Fire kit fit a kiln I bought somewhere else?
Yes, as long as it's a model in the table above. The kit is matched to the chamber, not to the invoice. Tell us the model and serial number and we'll confirm the fit.
Firing on day one
You've already waited for the kiln and paid an electrician. The furniture is the cheapest part of the project and the one most likely to be the thing standing between a delivered kiln and a first firing.
- Tell us your model and we'll match the kit. One phone call, no guessing at shelf geometry.
- Flat-rate freight with liftgate on every kiln. Kit shipping is calculated on weight, and shelves are heavy — we'll quote it with the kiln so there are no surprises.
- We price match. Find it cheaper and tell us where.
- Studios, schools and purchase orders: commercial quotes and educational pricing.
