If you fire your own ceramics, you already know the firing record is where the craft lives. The kiln doesn't care how good your forms are — what matters is the cone you reached, the ramp you ran, how long you held at temperature, and whether the atmosphere was oxidation or reduction. KilnLog turns the loose notebook pages and phone photos into a searchable, private firing logbook.
Open KilnLog — it's free →For each load you can record the date, firing type (bisque, glaze, single-fire), the kiln, your cone target (∆04, ∆6, ∆10…), the firing schedule or program number, the maximum temperature in °F or °C, hold/soak time, and the kiln atmosphere. A one-to-five result rating plus free-text notes capture what actually came out — pinholes, crawling, a perfect celadon, an underfired cone pack — so next time you can reproduce the win or avoid the mistake.
Cone is heatwork, not just temperature: a fast ramp and a slow ramp to the same peak give different results. KilnLog lets you note the exact schedule per firing, and Pro adds a reusable schedule library so your "Slow Cone 6 glaze" program is one tap away on the next load. No more guessing which program you ran last time the glazes looked right.
Keep a glaze reference list with names, cones and recipes. Mention a glaze in a firing's notes and KilnLog's Pro glaze-results matrix shows how that glaze performed across firings — average result and your best firing for it. It's the difference between "I think Floating Blue likes a slow cool" and knowing it.
