The Ultimate Care Guide for Handcrafted Ceramics | Merme

Introduction: Honoring the Artisan’s Craft

When you invest in handcrafted studio pottery, you are not merely purchasing tableware or a decorative vase; you are adopting a piece of geological history. Whether it was born in the turbulent ash of a wood-fired kiln, kissed by the vapor of soda firing, or forged from high-fired stoneware, your ceramic piece was designed to outlast you. 

However, "heirloom quality" does not mean invincible. The longevity of your pottery depends entirely on how it is integrated into your daily rituals. 

For the conscious consumer, caring for handcrafted ceramics is an extension of the "Slow Living" philosophy. It is an act of mindfulness - a daily practice of respecting the earth and the artisan’s labor. At Merme, we believe that understanding your pottery is the key to preserving its quiet, intentional beauty. 

Here is the ultimate guide to caring for your wood, soda, and high-fired stoneware.

Understanding Your Ceramics: The Power of Vitrification

Before discussing how to clean your pottery, it is vital to understand why it is so durable. 

The functional tableware in Merme’s AVYAJ and SAHA collections (mugs, plates, and serveware) are made from high-fired stoneware or porcelain. During the firing process, the kiln reaches temperatures exceeding 1,250°C (2,300°F). At this extreme heat, the silica within the clay melts and fuses together, turning the porous earth into a dense, glass-like material. 

This process is called vitrification. Because vitrified stoneware is non-porous, it will not absorb water, food bacteria, or odors. It is incredibly strong, dense, and perfectly suited for the rigors of a modern Indian kitchen.

Daily Rituals: Washing and Maintenance

Are Handcrafted Ceramics Dishwasher Safe?

Yes. Because our stoneware is fully vitrified and fired to such extreme temperatures, the clay body and the glaze are permanently fused. The intense heat of a standard dishwasher cycle will not harm the structural integrity or the glaze of your wood-fired or soda-fired tableware. 

The Golden Rule: While the dishwasher itself is safe, the real danger is "clinking." High-pressure water jets can cause plates and mugs to rattle against each other. If a Wabi-Sabi mug with a delicate rim repeatedly strikes a heavy metal pot, it will chip. Always ensure your ceramics are loaded securely, with ample space between pieces.

Hand Washing for Longevity

For those who practice mindful, slow-living rituals, hand washing is always the preferred method of care. The tactile experience of washing a textured, soda-fired bowl connects you back to the object. 

• Use warm water and a mild, eco-friendly dish soap.
• Avoid highly abrasive scouring pads (like steel wool), which can dull softer, matte glazes over time. Opt for a soft sponge or a natural bristle brush.

Navigating Temperature: Microwaves and Ovens

Handcrafted stoneware is exceptionally resilient to heat - after all, it was born in a 1,250°C fire! 

Microwave Safety

Merme’s functional stoneware is generally microwave safe. It is perfect for reheating your morning coffee or a bowl of soup. 

The Exception: If your specific piece features metallic luster overglazes (like real gold or platinum accents, though rare in traditional Wabi-Sabi styles), it must never go in the microwave.

Oven Safety and "Thermal Shock"

Stoneware retains heat beautifully, making it ideal for serving warm dishes during festive gatherings. It is oven-safe, but you must be incredibly careful to avoid thermal shock.

Thermal shock occurs when a ceramic piece experiences a rapid, extreme change in temperature, causing the clay to expand or contract too quickly. This will cause the piece to crack or shatter violently.

• NEVER take a cold ceramic dish from the refrigerator and place it directly into a hot oven.
• NEVER pour boiling water into a freezing cold mug.
• ALWAYS allow the pottery to come to room temperature first, or place the room-temperature dish into a cold oven and allow them to heat up together.

Erasing the Marks of Time: Stains and Scratches

Over years of daily use, even the highest-quality stoneware will develop a patina. This is the Wabi-Sabi philosophy in action - the beauty of use and age. However, some marks can be easily removed.

Removing Tea and Coffee Stains

The tannins in black tea and dark coffee can leave superficial brown stains on the interior of lighter-glazed mugs. Because the clay is vitrified, these stains are only on the surface; they have not soaked into the pottery.

• The Fix: Create a simple paste of baking soda and a few drops of water. Gently rub the paste over the stain with a soft cloth or your finger, and rinse. The gentle abrasion will lift the tannins immediately.

Silver Marks from Cutlery

Sometimes, you may notice gray or silver scratch marks on the bottom of your plates or bowls. These are not scratches in the glaze! Handcrafted ceramic glazes are often much harder than the metal alloys used in modern cutlery. Those silver marks are actually tiny deposits of metal that have rubbed off your fork or knife onto the plate.

• The Fix: A specialized ceramic cleaner (like Bar Keepers Friend) or a gentle baking soda paste will easily buff these metal marks away, restoring your plate to its original beauty.

A Note on Raku and Sculptural Pieces

The guidelines above apply strictly to functional, high-fired stoneware (like the AVYAJ and SAHA collections). 

Pieces from our ADWAI Collection, particularly those that are Raku-fired, require entirely different care. Raku is a low-fire, rapid-cooling technique that leaves the clay highly porous and fragile. 

• Raku pieces are strictly decorative. 
• They are not food-safe, not water-tight, and must never be placed in a dishwasher, microwave, or oven. 
• To clean a Raku vase, simply dust it with a dry, soft cloth. Do not use water or liquid cleaners, as they can seep into the porous clay and damage the crackle glaze.

FAQ: Ceramic Care

Can I put a Wabi-Sabi vase in the dishwasher?
If it is a high-fired wood or soda vase, yes, technically. But due to their awkward shapes and the risk of clinking, tall vases should always be hand-washed to prevent chipping the delicate rim.

Why does my unglazed pottery feel rough?
The unglazed exterior (the bare clay) is a hallmark of atmospheric firings, designed to connect you to the earth. It is perfectly safe to wash. If it absorbs oil from your hands over time, simply wash it with warm, soapy water.
