Purple Clay Pot is a kind of traditional Chinese pottery made from purple clay. It is widely used for brewing tea and making Chinese herbal medicine due to its excellent air permeability, wettability, and heat insulation. The color of the pot changes over time, making it a collectible item as well. It is not only used for practical purposes but also highly regarded in terms of aesthetics.
Many people like to drink tea with a purple clay pot, but don’t understand why it is better to brew tea in a purple clay pot or how it is made. With the improvement of modern living standards and the pursuit of health and longevity, people will favor pure and non-toxic purple clay teaware. Let’s learn something about purple clay pots today!

Nowadays, many artists in order to pass off inferior products as superior ones, mix low-quality purple clay with some chemical substances, pretending it is high-quality purple clay, or even worse, mix ordinary clay with additives and claim it is purple clay to make pots. Not only do they deceive purple clay enthusiasts, but also cause harm to human health directly.
Here, we have compiled some basic knowledge about purple sand pots, hoping that it can help players and tea lovers select a good one.

Why is Zisha Tea good?
Using a purple sand teapot to make tea is the best way, as the structure of purple sand ore is double airhole structure. Its unique chemical structure makes purple sand the best raw material for making tea.
The advantages of double-spout structure for teapots are twofold.
Slow heat conduction: This way of making tea can quickly release the aroma and beneficial substances of the tea leaves without making them old and releasing harmful substances. With a good purple sand pot, you can have a sense of danger when making tea, and the scene of clouds and mist floating around after pouring the body of the pot.
The double-hole structure of purple clay mud can absorb the aroma of tea water, “occupy as its own”. This is also why purple clay teapot “One pot does not serve two teas”. A pot, only one kind of tea, absorb a kind of aroma, over time, this pot has a kind of tea aroma. Even if you don’t put tea leaves and pour hot water into the teapot, the water poured out also has this kind of tea aroma.
If your teapot is oiled, you are in trouble because the oil has been sucked into the double air holes, and it takes much longer time to clean it up by opening the lid again.

Classification and Colors of Purple Clay:

Purple clay is categorized in two main types, namely, black purple clay and red purple clay. Black purple clay has a glossy black color while red purple clay has a reddish hue.
How to judge a good pot?

1. Check the materials: A good pot should be made of high-quality material, such as stainless steel and aluminum alloy.

2. Look at the inner coating: A good pot should have a smooth non-stick coating that is easy to clean and will not react with food.

3. Observe the lid: The lid should fit tightly onto the pot and maintain pressure inside while cooking. It should also have vents to release steam and prevent boiling over.

4. Examine the handle: The handles should be ergonomic, durable, heat-resistant and comfortable to grip.

5. Test for heat transfer: A good pot should evenly distribute heat without hotspots or cold spots, ensuring an even cooking temperature for your food.
When starting to play with a pot, it may be the same as many people, starting from its shape. In fact, this kind of play is not a good way to get started. Moreover, the shape of the pot is also very particular. Unless we have seen many old pots and good pots, we can tell that the shape of one pot is very good at first sight.
Translation: Clay

The first lesson of purple sand pot is about the material of purple sand. The effect of sand quality can be achieved by weathering the purple sand ore from rocks to particles, then grinding it with a stone mill into foam with particles. Adding water to make mature mud and then making teapots. This primitive mud processing method can maintain the air permeability of the pot, making its daily function well, and the excellent material particle effect makes the sound of the pot deep, heavy, sandy and dumb.
The best particle size for sandstone is 32-60 mesh. The original processing method can make the teapot feel smooth and comfortable. No matter the surface of the purple clay pot is slightly purple, slightly red, pink or bean purple, it should have a feeling of being oiled after a short maintenance period, not dry and dull, showing no vitality like an old person’s skin.
Nowadays, many craftspeople remove iron in the powder and even eliminate other minerals such as quartz after grinding ore into powder, which makes the teapots look very delicate. In fact, they are only pursuing how to make good teapots and make them conveniently without understanding the true meaning of why purple sand ore is used to make teapots. After all, if there are a lot of other minerals in the purple sand mud, higher requirements will be put on processes like making teapots and firing. If you’re not careful enough, you may end up with a failed teapot.
Although some of the works of young and middle-aged artists look like they are carefully crafted with materials, in actuality they have disrupted the functionality that should be inherent in purple sand ware. True masters of purple sand ware who really understand the material will not remove those mineral particles, so if you take a closer look at their works, you can find the mineral particles on the surface, but when you touch it, it still feels as smooth as a baby’s skin.
Two: Pot-shaped
No matter traditional or modern, the shape of purple sand pot pays great attention to its beauty in points, lines and surfaces. It requires perfection and novelty in overall design of the pot body, with people-oriented and humanized design. The pot body should be dignified and reasonably match up the functions of spout, handle and button.
For those who love kettles, firstly distinguish between fully handmade and hand-made kettles, observe whether the body shape of the kettle is beautiful and has personality of work. The key is whether the structure of the body is coordinated. If it is a glossy surface, whether the transition from spout to handle is natural, and whether the workmanship is delicate, clean and neat. For a good kettle, observe whether the water flows smoothly and cleanly, whether it takes less effort to open the lid, and whether the cover is tight.

The tightness of the lid should be supplemented. Now many people take the tightness of the lid as an important criterion for judging whether a kettle is good or not. This is a misconception. Many kettles made by the older generation have certain gaps between the lid and body, feeling loose and slack. When pouring water, the lid will absolutely not seep out water. And when pressing the vent on the lid, the water will stop flowing.
Why do many young and middle-aged artists now make flower vases or new-style vases? The old generation of artists told me that there is only one reason: their skills are too poor and they are too eager for quick success. Making antique vases, because there is a comparison, you can tell the good and bad when you take it out. Doing new vases, only a small number of purple sand artists know their skills are poor, but most purple sand lovers are difficult to detect.

Modern teapots made with pottery techniques pay attention to the artistic interest of shapes, seek stability in irregularities, look for regularity in changes, fully show the spirit of the work, pursue the artistic effect of the work, and pursue the feeling of returning to simplicity. Transform from existing pottery rules into an unfathomable state, fully enjoy the beauty.
