## What is GlazeGrid?

GlazeGrid is a local firing record for ceramicists who use witness cones.

After unloading a kiln:

• See a kiln cross-section divided into top, middle and bottom zones.
• Drag each witness reading to the position where it sat.
• Record only the visible state: Upright, Bent, Overfired or Unread.
• Compare the recorded state mix for each kiln zone.
• Keep your own observation beside the physical position and target cone.
• Share a factual heat-profile record through the iOS share sheet.

Start with a clearly labeled local sample. The free path works without an account, network connection or developer-controlled sync. GlazeGrid does not control a kiln and does not calculate temperature, chemistry or firing safety.

GlazeGrid Pro is an optional one-time unlock for additional local heat maps and firing history. Your existing records remain readable without purchase. There is no subscription.

Your records stay on this device in V1. No ads, tracking or remote backup.

This app records what you observed. It does not decide whether a glaze is safe, food-safe or suitable for a firing.
