Clay pots have been part of Indian households for generations. From storing drinking water during the summer to preparing traditional dishes, earthenware continues to be valued for its simplicity and natural appeal.

Even with refrigerators and modern cookware widely available, many families still prefer a traditional matka for naturally cool drinking water. Similarly, clay cookware remains popular among people who enjoy traditional cooking methods.

However, buying a new earthen pot isn't just a practical decision for some households. Traditional Vastu beliefs associate certain days and timings with purchasing and bringing clay items into the home.

According to these beliefs, some days are considered less favourable for buying earthenware, while daylight hours are generally preferred. At the same time, practical factors such as cracks, leakage, glaze and the quality of the pot should be considered before making a purchase.

Here's what traditional Vastu beliefs say about buying clay pots and what you should actually inspect before bringing one home.

Which Days Are Considered Unsuitable for Buying Clay Pots?

According to traditional Vastu-related beliefs, Sunday and Tuesday are generally considered days on which people should avoid purchasing new clay pots.

Tuesday receives particular attention in some astrological traditions because it is associated with Mars, or Mangal. Since Mars is linked with land and the earth element in certain traditional interpretations, bringing a newly purchased earthen item into the house on this day is sometimes discouraged.

Some traditions also advise against purchasing clay utensils on Saturday.

These restrictions, however, come from traditional and astrological beliefs. There is no scientific evidence showing that purchasing an earthen pot on a particular weekday affects luck, finances or household well-being.

People who follow Vastu or traditional customs may choose to consider these practices, while others can base their purchase entirely on convenience and product quality.

Why Do Some Traditions Discourage Buying Clay Pots After Sunset?

Timing is another consideration mentioned in traditional beliefs.

According to some Vastu practices, a new earthen pot should ideally be purchased and brought home during daylight hours rather than after sunset.

Evening or nighttime purchases are considered unfavourable in certain traditions. Therefore, people following these customs generally prefer to buy a matka or other clay cookware during the day.

From a practical perspective, daylight can also make it easier to examine an earthen pot properly. Small cracks, uneven surfaces and manufacturing defects may be easier to notice under good lighting.

So, whether or not you follow Vastu, inspecting pottery in adequate light can be useful.

Be Careful When Buying Brightly Coloured Clay Pots

Appearance can play a major role when choosing earthenware. Markets now offer clay pots in numerous designs, including painted, polished and highly decorative versions.

However, if the pot is intended for drinking water or cooking, appearance shouldn't be the only consideration.

Some decorative earthenware may contain paints, coatings or glazes that are not designed for food contact. This does not mean every coloured or glazed clay pot is unsafe, but consumers should check whether the product is specifically labelled or certified as food-safe.

Avoid using pottery of unknown origin for cooking or drinking if you cannot determine whether its glaze, paint or coating is suitable for food contact.

For decorative purposes, the choice is naturally much broader.

Check for Cracks Before You Pay

Clay pots are relatively fragile and can develop fine cracks during manufacturing, transportation or storage.

Before purchasing one, inspect the entire surface carefully.

Look around the bottom, sides, neck and rim for visible cracks or damaged sections. Even a tiny crack may eventually result in leakage or cause the pot to break more easily.

You can also gently tap the pot to assess it.

Traditionally, buyers listen for a clear, ringing sound when tapping an earthen pot. A noticeably dull or uneven sound can sometimes indicate a crack or structural defect.

However, this should only be treated as a quick preliminary check rather than a guaranteed method of determining quality.

Perform a Water Leakage Test If Possible

If the seller permits it, testing the pot with water can be another useful step.

Fill the earthen pot and observe whether water begins leaking rapidly through any particular crack or damaged area.

Keep in mind that unglazed earthenware is naturally porous. A small amount of moisture or "sweating" on the outer surface can therefore be normal and is different from water leaking through a crack.

A clearly damaged pot, however, may lose water much faster and should generally be avoided.

Clean a New Clay Pot Before Using It

Never assume that a newly purchased clay pot is ready for immediate use.

Dust and other particles can settle inside during manufacturing, transportation and storage. Wash the pot thoroughly before using it for drinking water or food preparation.

Some types of traditional clay cookware may also require soaking or seasoning before their first use. Follow the manufacturer's instructions when available, particularly for cookware that will be exposed to heat.

Sudden temperature changes should also be avoided because thermal shock can crack some types of earthen cookware.

Tradition and Practical Safety Can Go Together

For people who follow Vastu, avoiding Sunday and Tuesday—and, according to some beliefs, Saturday—for purchasing clay pots may be part of their household tradition. Similarly, they may prefer bringing new earthenware home before sunset.

These practices should be understood as cultural and traditional beliefs rather than scientifically proven rules.

Regardless of which day you shop, product quality deserves greater practical attention. Check the pot for cracks, inspect it carefully, test for leakage where possible and make sure any paint or glaze used on cookware or drinking vessels is suitable for food contact.

A carefully selected and properly maintained clay pot can remain a useful addition to the kitchen, whether you choose it for tradition, everyday convenience or simply the experience of drinking naturally cool water from a matka.
