Bisque is a studio journal for potters and clay artists: follow every piece from wet clay to finished pot, keep your glaze recipes in one library, and log every kiln firing. TRACK YOUR PIECES Move each piece through its stages with a tap: in progress, drying, bisque ready, bisqued, glaze ready, glazed, fired, then sold, given away, broken or recycled. Add photos, the clay body, the glaze you plan to use, size and notes, and see where everything sits in your studio. BUILD YOUR GLAZE LIBRARY Record each glaze you mix: ingredients with percentages and additions, cone, atmosphere (oxidation, reduction, neutral, soda, salt, wood), surface (gloss, satin, matte, dry matte, crystal), color, application notes and a rating. Mark it untested, testing, proven or retired. LOG YOUR FIRINGS Bisque, glaze, lustre, raku, pit or saggar, salt or soda, wood. Note the kiln, cone and atmosphere, build the ramp schedule segment by segment (target temperature in °F or °C, rate, hold), and record cone pack results, firing time, cost and the outcome. Each cone shows its temperature from the Orton chart. UMF CALCULATOR (PRO) Turn a recipe's ingredient percentages into its Unity Molecular Formula, using a built-in database of common glaze materials (feldspars, clays, frits, fluxes and colorants), and check its fluxes, silica and alumina against typical ranges for the glaze's cone. AI STUDIO ASSISTANT (PRO) Ask about glaze defects such as crawling or pinholing, throwing a difficult form, or reduction and oxidation, and get an answer from an AI assistant powered by Grok (30 questions a day). FREE - Up to 10 pieces (3 photos on each), 5 glazes and 5 firings - Studio counts and recent activity on the home screen BISQUE PRO - Unlimited pieces, glazes, firings and photos - UMF calculator - AI Studio Assistant Bisque Pro is a monthly or yearly subscription that renews automatically.

Bring your winning recipe to the next piece. KilnNote is a pottery record-keeping app for glazes, firing logs, and progress tracking. "I nailed that celadon combo once — and then I couldn't reproduce it." Sound familiar? KilnNote keeps every glaze, clay, and firing detail in one place so you can reproduce what worked. 【What you can do】 ▷ Log works piece by piece Save bisque, glaze application, and final firing temps, glazes used, and results (Success / Review / Fail) as a step-by-step log. Every decision, always at hand. ▷ Progress at a glance Auto-status from the latest firing result — Success, Review, Fail, or Not Started. See it in the list or detail view instantly. ▷ Tags & search Organize works with free tags like "Exhibition" or "Class piece." Filter by tag or title, and the search state stays put as you navigate. ▷ Glaze master Record glaze name, maker, and color notes — plus attach a glaze sample photo. From each glaze, trace every piece and firing that used it. ▷ Pinch-to-zoom Zoom into work, firing, and glaze sample photos to check texture and color up close. ▷ Export & import (free) Back up as CSV, PDF, or photo ZIP. Import from CSV or ZIP. Great for device migration or class notes. ▷ Board view (Pro) See all works organized by status — Success, Review, Fail, Not Started — like pieces arranged on a studio shelf. ▷ Test piece comparison (Pro) Slide between two photos to compare glaze colors and textures side by side. ▷ Duplicate a work (Pro) Clone a successful work as a template. Carry the same firing steps into a new piece. 【Who it's for】 ・Potters who want to reproduce a glaze success ・Studio potters managing multiple test tiles ・Beginners who want to track what they learned in class ・Anyone who can't remember which glaze combo worked last time ・Home potters who want a private, offline log 【Your data stays on your device】 All work data, photos, and firing logs are stored locally on your iPhone/iPad.
