What is raw mineral glaze?

At SaraGaia, we see ourselves as humble apprentices to nature, selecting stones that have slept in the earth’s crust for millions of years and allowing them to speak through fire.

What you hold is a dialogue between earth and flame — geological time, solidified. Ocher, rich in iron oxide, transforms under reduction into the crystallized olive depth of our Tea Dust glaze. Malachite, a copper-bearing mineral, emerges from the kiln as the tender blush of Peach Bloom or the intensity of Pomegranate Red. Sumali, the historic cobalt pigment, gives rise to Sea Sparkle — a shifting, star-like blue shaped by mineral composition and flame. Each glaze is not applied, but revealed — a record of mineral, heat, and time.

Care and Use

To preserve the beauty and functionality of raw ore glaze ceramics, follow these care instructions:

Before First Use

  • Initial Cleaning: Rinse the cup thoroughly with warm water to remove any dust.
  • Optional: For enhanced durability, you can fill the cup with boiling water, let it sit for 10-15 minutes, then empty and dry it. This helps to seal the glaze slightly.

During Use

  • Temperature Considerations: These cups are suitable for hot beverages like tea or coffee, but avoid sudden extreme temperature changes. Do not place a cold cup directly on a hot stove or pour boiling water into a cup that has just been in the refrigerator, as this may cause cracking.
  • Beverage Compatibility: They work well with most drinks, but it's best to avoid prolonged contact with highly acidic or alkaline substances, as they might gradually alter the glaze's appearance over time.

Long-Term Care

  • Storage: Store the cup in a dry, well-ventilated place. If stacking cups, place a soft cloth or paper towel between them to prevent scratches.

By following these guidelines, your raw ore glaze ceramic cup will retain its natural beauty and provide you with years of enjoyment. Each cup's unique glaze variations are part of its character, so embrace the subtle changes that come with careful use!
