Glass & Ceramics

Ceramics

Durable, inert, and built to last generations

Ceramics include earthenware, stoneware, and porcelain — all made from natural clay fired at high temperatures. They're generally inert and non-leaching when properly glazed, making them safe for food contact. Stoneware and porcelain are especially durable and temperature-resistant.

Sustainability benefits

  • Generally inert and non-leaching when lead/cadmium-free
  • Extremely durable and temperature-resistant
  • Can be repurposed creatively (mosaics, garden drainage)
  • Made from natural clay materials

Drawbacks to consider

  • Not accepted by most municipal recycling programs
  • Brittle — especially earthenware
  • Must verify glazes are lead and cadmium-free

What to look for

Stoneware and porcelain are the most durable options. Always verify with the manufacturer that glazes contain no lead or cadmium.
