The first fire

Every bad first pizza has the same cause, and it is not the dough: the oven was not hot enough.
Every bad first pizza has the same cause, and it isn't the dough: the oven wasn't hot enough. A pizza oven is a machine for putting a stone at 400-450°C under a dome that's hotter still, and until it's there, nothing else you do matters. This bake is about getting there: lighting, the thirty-minute wait, reading the dome as it turns from black to white, and the one number that means go.
Setting up, once
Site the oven on a stable, non-flammable surface — a metal stand or a stone table, never a wooden picnic bench — with a metre of clear air around the mouth and chimney, away from anything overhanging. Wind matters more than people expect: a breeze into the mouth blows heat out, so turn the oven's back to the prevailing wind. Have the peel, the turning peel, the infrared thermometer, a heat-proof glove and a bowl of water on a side table before you light anything. Read the manual's first-fire instructions: many ovens want a gentle curing burn to drive moisture out of the stone before a full-heat session.
Lighting a wood oven
Small dry kindling and one firelighter in the tray at the back; a few thin splits on top once it catches; the door on if the oven has one, chimney fully open. Feed it small pieces — the size of a hand — every five to eight minutes, keeping a live flame rather than a heap of smouldering logs. Smoke pouring from the chimney means wet wood or too much of it; a clean, near-invisible heat shimmer means it's right. Kiln-dried hardwood, in the smallest splits you can buy, is the single biggest upgrade to a wood oven's behaviour. Pellet ovens simplify all this: fill the hopper, light, wait, top up.
Reading the dome. The inside of the roof goes black with soot as the oven heats. Somewhere around twenty to thirty minutes, the black burns off and the dome turns white or pale grey, from the back forward. That white line is the oven telling you the roof is past 400°C. When the whole dome has cleared and the stone reads 400°C or more on the infrared thermometer, aimed at the middle of the floor, you are ready — not before, however hungry anyone is.
Lighting a gas oven
Bottle connected and checked for leaks with soapy water on the joints (bubbles mean tighten), burner on high, door on, and fifteen to twenty minutes of waiting. The dome clears the same way; the stone reads the same number. Then the burner comes down to medium for baking, because at full gas the top of the pizza burns before the base is done — the reverse of the wood-oven problem. Every gas oven has a sweet spot on the knob; find it on your second session and mark it with a paint pen.
The thermometer that isn't optional
An infrared thermometer — the point-and-read kind, about the price of a bag of good flour — is how you know the stone temperature, which is the only number that matters. The oven's own gauge reads the air near the roof and will confidently say 450°C while the stone sits at 300°C and turns your base pale and floppy. Aim the infrared at the centre of the floor from the mouth: 400-450°C for classic Neapolitan-style pizza, 350-400°C for a slightly slower, crisper bake. After each pizza the stone drops 30-50°C where the pizza sat; wait a minute, or shift the next pizza to the other side of the floor.
Managing heat through a session
Wood: keep a small live flame at the back throughout, adding one hand-sized split every pizza or two. If the flame dies to embers, the dome cools and the top of the pizza stops cooking; if it roars, the top blackens. Gas: the knob, adjusted from what the last pizza's top looked like. Both: give the stone its minute between pizzas, and rotate which side of the floor you launch onto. Bake 07 turns this into a rhythm for eight people.
Questions from the fire
How long does a session take, start to shutdown?
Wood: thirty minutes to heat, an hour or two of baking, then let the fire die and the oven cool with the door on — two hours before it's safe to cover. Gas: twenty minutes to heat, bake as long as you like, turn off, cool for an hour. Never cover a warm oven or move a hot one.
The oven smokes for the first ten minutes. Normal?
Yes, for wood — the kindling stage smokes until the fire is hot enough to burn its own smoke. Persistent smoke after that means damp wood, too much wood, or the chimney part-closed. If a neighbour's window faces your chimney, light earlier in the evening while people are out, and use the driest wood you can get.
Can I leave the oven hot and unattended?
No — a fire is a fire, and a 450°C steel box is a hazard for children, pets and anyone who doesn't know it's hot. Someone stays with it from lighting until it's cooled, and the water bowl stays beside it. This is the least negotiable line in the notebook.
Stone at 430°C — now what goes on it: dough for a hot oven.
