# Ceramic Hang Visual BOM Brief

## Goal

Create an image-forward one-page visual BOM that explains the ceramic handpan workflow at a glance: digital master, plaster mold, cast shells, tone fields, support fixtures, finishing, and measurement tools.

## Layout

- Header: "Ceramic Hang - Slip-Cast Tonal Vessel Research Build".
- Hero image: CAD/render or finished prototype clearly labeled as concept/prototype.
- Process strip: tone coupons -> master print -> plaster molds -> greenware shell -> bisque measurement -> final finish.
- BOM table: item number, material/tool, quantity, spec, make/buy, cost/date status, image.
- Physics inset: plate/tone-field model plus gu Helmholtz model.
- Validation inset: field ID, target note, measured pitch, decay, crack status.

## Required Images

- Upper shell CAD/render.
- Lower shell/gu CAD/render.
- Tone coupon test set.
- Mold halves.
- Greenware shell in drying cradle.
- Firing support/ring.
- Measurement setup with mic/tuner.
- Finished or bisque prototype.

Generated images or CAD renders should be marked as placeholders until replaced by shop photos.
