# Sketching Your Cast Objects

> **5c2.** Create a sketch of two objects to cast in metal. Include each component's dimensions on your sketch, which need not be to scale.

Casting starts long before the metal melts. A good sketch helps you choose an object that can actually be molded, vented, and poured successfully.

### Think About Castability

Some shapes look great on paper but are hard to cast well. Very thin sections may cool too quickly. Deep undercuts may not release cleanly from a simple mold. Tiny decorative details may disappear if the mold material cannot hold them sharply.

That is why beginner castings are often simple objects such as:

- medallions or tokens
- small plaques
- simple hardware pieces
- decorative pendants
- flat-backed symbols or emblems

**Casting Sketch Checklist** — Review these before asking for approval

- [ ] **Overall dimensions shown**: Length, width, and thickness are clear.
- [ ] **Shape is realistic for a mold**: No hidden spaces that a simple mold cannot support.
- [ ] **Pattern source considered**: One casting uses a counselor-provided pattern; one uses your own approved pattern.
- [ ] **Pouring thought ahead**: You can imagine where the metal might enter and where air might escape.

A strong sketch proves you are thinking like a founder instead of just drawing an object. The next step is building the molds and bringing molten pewter into that planned space.
