Kiln Firing & Glaze Test Log
Every potter has had the beautiful surprise they can’t reproduce — the glaze that broke just right on one tile and never again. The difference between a surprise and a recipe is a written row. These two pages are the single most useful thing you can pin by a kiln.

What it does
- A print-and-use kiln firing log — one row per firing for date, type, cone, schedule, top temp, witness-cone result and what came out.
- A glaze test-tile log — record the recipe, the variation, the clay and the result, so a beautiful surprise becomes one you can repeat.
- A cone & temperature quick reference from cone 010 to cone 10, in both °F and °C, to keep by the kiln.
- Room to record the variables that actually change a result — placement in the kiln, thickness of application, and the clay body underneath.
- Prints on US Letter or A4 and survives a studio.
Own it, don't rent it
Want to know what a mug costs to make?
These two pages record a firing. The full workbook runs the business side of the studio — a glaze recipe library that scales to any batch, kiln and firing records across a season, clay and materials inventory, a true cost-per-piece that includes clay, glaze, firings and your hours, and the pricing that turns all of it into a number you can charge.
A one-time purchase you keep firing after firing — the owned system between a notebook by the kiln and pricing on instinct.
A studio reference, not certification or safety advice. Cone temperatures are approximate and vary by kiln, schedule and placement; glaze food-safety and material handling are yours to verify with your supplier and, where required, testing.
