How to Cure Your Unglazed Clay Vessel for Daily Use

Your beautiful unglazed clay vessel can be both a stunning decor piece and a functional mug or cup with a little care! Here’s an easy way to prepare (or “curar”) for everyday use:

1. Give it a gentle rinse. Start by rinsing your vessel with warm water to remove any dust. Skip the soap since unglazed clay soaks it up.
2. Soak it in water. Let the vessel sit submerged in clean water for about 24 hours. This helps the clay absorb moisture evenly, so it won’t drink up your coffee or tea later!
3. Simmer in rice water (optional). Boil some rice in water, then simmer your vessel in that starchy water for 30 to 60 minutes. The natural starch helps seal the pores a bit.
4. Air dry thoroughly. Let your vessel dry completely in a well-ventilated spot.
5. Seal it naturally. You can either lightly rub food-safe oil (like flaxseed or mineral oil) inside and out to protect it, reapplying every few weeks...

OR

Use beeswax. Warm a small amount of food-grade beeswax and gently rub it onto the surface. This creates a natural waterproof layer while keeping the vessel breathable.

6. Ready to use! Now your vessel is ready for daily use. Just remember to avoid harsh soaps and sudden temperature changes to keep it lasting longer.

Enjoy your one-of-a-kind piece perfect for sipping or displaying!

Can Step 5 Be Skipped? What Else Can You Use? How Often Should You Cure?

Can you skip step 5 (sealing with oil or beeswax)?
Yes, you can skip the sealing step, but keep in mind that unglazed clay is porous. Without sealing, the vessel will absorb liquids more easily, which can lead to stains, odors, or even weakening over time. So, sealing helps protect your piece and makes it easier to clean and use daily.

What else can you use instead of oil or beeswax?

• Food-safe wax blends made specifically for pottery are a great option.
• If you prefer a fully natural approach, simply curing and frequent drying (and careful use) can help, but the vessel will require more maintenance.

How often should you cure or seal your vessel?

• The initial curing process (steps 1–4) is usually done once before first use.
• If you use oil or wax, reapply every few weeks or when the surface looks dry to keep the seal effective.
• Regular reapplication helps maintain protection and keeps your vessel looking and performing its best.

Sealing isn’t absolutely required but highly recommended for daily use and longevity. If you skip it, just be gentle with your vessel and dry it thoroughly after use.

Caring for Your Unglazed Clay Vessel

• Avoid soap if possible: Since unglazed clay is porous, it can absorb soap and affect the taste or smell. It’s best to rinse with warm water only.
• If you must use soap: Use a very mild, fragrance-free soap sparingly and rinse thoroughly right after.
• Dry thoroughly: Always let your vessel air dry completely after washing to prevent moisture buildup and potential mold.
• Avoid soaking: Don’t leave the vessel soaking in water for long periods after curing, as this can weaken the clay.
• Handle gently: Unglazed clay is more fragile than glazed ceramics, so avoid sudden temperature changes (like pouring boiling water into a cold vessel) and be gentle with it.
