# Supplier RFQ - Ceramic Hang

Subject: RFQ - materials and services for slip-cast ceramic tonal vessel prototype

Hello,

I am prototyping an 18 inch slip-cast ceramic tonal vessel and need pricing/lead time for the following items or services:

- Cone 6 stoneware or porcelain casting slip with published shrinkage and firing schedule.
- #1 pottery plaster or equivalent pottery mold plaster, 75 lb class quantity.
- Optional large-format 3D print service for an 18-20 inch dome master, or segmented master parts.
- Kiln-safe refractory support material or custom setter/ring options.
- Optional padded case suitable for a fragile 18 inch ceramic handpan-style object.

Please include:

- Unit price and quantity breaks.
- Current availability and lead time.
- Shipping estimate to Santa Clara, CA.
- Technical data sheet or material specification.
- Recommended substitutes if the exact item is unavailable.

Notes:

- Shrinkage and firing schedule are critical.
- The first run is prototype/research scale, not production volume.
- If substitutions are proposed, please include material compatibility and firing temperature notes.

Thank you,

Tony Koop
