Calculate how much glaze you need for your pottery.
Covers dipping, brushing, and spraying for bowls, mugs, and vases.
Glaze Needed
Pottery glaze coverage depends on the application method and piece size.
Surface area estimates for common shapes:
- Mug: ~50 sq in (320 sq cm) — cylinder + handle
- Bowl (6 in/15 cm): ~80 sq in (515 sq cm)
- Dinner plate (10 in/25 cm): ~110 sq in (710 sq cm)
- Vase (8 in/20 cm tall): ~120 sq in (775 sq cm)
Glaze coverage by method:
- Dipping: ~1 pint covers 6–8 sq ft (0.55–0.75 sq m)
- Brushing: ~1 pint covers 4–6 sq ft (0.37–0.55 sq m) — needs 2–3 coats
- Spraying: ~1 pint covers 5–7 sq ft (0.46–0.65 sq m)
Glaze thickness:
- Standard: 1/16 inch (1.5 mm) when dipped
- Thin: good for detail, may show clay body
- Thick: richer color but risk of running
