Teapot buying tips
Choosing a good purple clay teapot is not just a new challenge for beginners, but also a serious consideration for seasoned enthusiasts. A teapot is more than just a functional item—it's an artistic piece that can be enjoyed and appreciated. Therefore, a high-quality teapot should excel in practicality, craftsmanship, and artistry. For those who love teapots, considering these three key aspects when making a purchase is essential.
Since teapots are used for brewing tea, their practical function is crucial. A well-designed teapot should have the right size and capacity, a comfortable handle, and a smooth spout to ensure ease of use. When choosing a teapot, it’s important to consider your personal tea-drinking habits, such as the pot’s capacity, the flow of the spout, and how it feels in your hand. Beyond functionality, the craftsmanship of the teapot reflects the skill of the artisan. A great teapot should have harmonious proportions between its spout, handle, lid, body, and base, with smooth transitions between shapes and lines. Additionally, the quality of the "mud, shape, engraving, and design" should be carefully examined.
"Mud":
The uniqueness of a Zisha (purple sand) teapot lies in the quality of its raw material—purple sand clay. Therefore, the first thing to consider when evaluating a teapot is the quality of the clay. Although the color of the clay may influence visual appeal, it doesn’t directly affect its functionality. However, over time, as the teapot is used and handled, the texture and feel become more important. High-quality purple sand clay has a subtle color and a non-greasy surface, which enhances the user experience. When purchasing a Zisha teapot, the quality of the clay should be one of the primary considerations.
"Shape":
The shape of the teapot represents its overall form and style. There are countless designs, each reflecting the creativity and effort of past artisans. It is often said that “no two teapots are the same.†Choosing the best shape depends on individual preferences, but from a cultural perspective, the ideal teapot should reflect the spirit of the tea ceremony—simple, elegant, and serene. The design should evoke a sense of antiquity and refinement, aligning with the traditional aesthetics of Chinese tea culture.
"Engraving":
This refers to the artistic elements of the teapot, such as calligraphy, poetry, and seal carvings. Unlike regular stamps, the engravings on Zisha teapots are often done by master artisans, combining the beauty of calligraphy and painting with the craft of pottery. These decorations reflect the rich traditions of Chinese art, including poetry, brushwork, painting, and engraving. As a result, appreciating a Zisha teapot involves understanding both the maker’s identity and the artistic value of the inscriptions.
"Function":
Functional beauty is different from mere aesthetic appeal. Over the years, the Zisha market has grown significantly, especially with increased involvement from Taiwanese traders. While many artists focus on the form and design, some overlook the practical aspects of the teapot. This can lead to issues like poor water flow or uncomfortable handling. A well-made teapot should have a balanced capacity, appropriate size, a tight-fitting lid, and a smooth spout. Based on common tea-drinking habits in Taiwan, a pot with a capacity of 30–50 milliliters is often preferred, as it is easy to hold and enhances the enjoyment of the tea ritual.
Zisha art is a reflection of life, elevated through creative expression. A truly great teapot must not only be beautifully shaped and skillfully crafted, but also feature a harmonious design, thoughtful decoration, and a meaningful artistic message. More importantly, it should be easy to use and bring a sense of calm and joy. As the late master Gu Jingzhou once said, art should be simple, honest, and expressive. Only then can a piece truly come alive and touch the heart. In this way, a perfect teapot becomes more than just a tool—it becomes a companion in the journey of tea and self-reflection.
Overview
The blue green algae controller (BGA controller for short) is a device that controls the content of blue-green algae (cyanobacteria) in water online. Utilizing a cyanobacteria sensor, the Blue Green Algae Meter monitors cyanobacteria content in real-time, preventing eutrophication, assessing water health, and safeguarding aquatic ecosystems.

Features
Daruifuno's Online Blue Green Algae Controller boasts a 3.2-inch LCD screen and a multitude of functions. Equipped with two SPST relays, it allows for high and low alarms, sensor cleaning control, and more. The controller also features two 4-20mA current outputs, customizable according to customer needs. With a two-wire RS485 interface and support for the Modbus communication protocol, the BGA Controller is powered by a wide voltage range (AC 100~240V or DC 18~36V), ensuring reliability even during power fluctuations.
Application Fields
The Blue Green Algae Controller is widely applicable in aquaculture, lakes, reservoirs, waterworks, swimming pools, landscape waters, and other water bodies requiring cyanobacteria control. During the hot summer months, when blue-green algae proliferate, causing water quality degradation and aesthetic issues, the BGA Controller effectively inhibits algae growth, enhances water quality, and maintains water clarity and beauty.
