This time, a detailed explanation on how to use seal paste was presented. Seal paste is a red material used when stamping seals in calligraphy and seal carving. The video covers everything from the basics of seal paste, practical usage, to troubleshooting. Seal paste is primarily made from mercurous chloride mixed with mugwort and oil, produced using secret techniques by Chinese craftsmen. Among the most famous are the Shanghai Zhenglingwei company seal pastes, and three types are introduced: "Guangming" (bright red with a gentle impression), "Yili" (dark red for a sophisticated look), and "Xizu" (glossy red and versatile).

Hello, this is Shodo Daisuki Shimauchi. Today, we are going to talk about how to use seal paste properly. What comes to mind when you hear "seal paste"? Most people think of the red ink used for stamping. In winter, it tends to be sticky and red.

It can stick to your hands and be hard to remove. In calligraphy classes, teachers usually help stamp the seals, so some may have never done it themselves.

I personally never stamped on my own before. So I wanted to see if people are really using seal paste properly.

This time, I will explain tips about seal paste and how to use it. Let's start by understanding what seal paste is. It is mainly made from mercurous chloride, called "Zhensha".

Mixed with mugwort fibers and oil, it's produced in China by artisans using secret techniques. The details are unknown, so I am speaking generally.

Seal pastes come in many types and colors, but Shanghai Zhenglingwei's products are famous. I will introduce three types: Guangming (bright red, gentle impression), Yili (dark red, chic), and Xizu (glossy red, versatile).

These are only examples; you can choose colors based on your work or personal preference. The unit "liang" is used to measure weight: 1 liang ≈ 30 grams.

Now, let's demonstrate using Shanghai Zhenglingwei's seal paste. Open 1/2 liang of Guangming. Remove the plastic cover. Direct stamping without preparation can flatten certain areas. Mixing the paste first is important.

Use the spatula to mix the paste thoroughly to prevent pigment and oil separation. Then roll it into a ball for versatile application.

Apply lightly on the seal. Use the "ink" backing sheet to stabilize the seal while pressing straight down. Apply evenly without pressing too hard. After use, roll the paste and store. Check about once a month.

For hardened paste, place near heat, use a hairdryer, or submerge in warm water. For sticky paste, absorb oil with paper or chill in fridge. Specialized grease or refined oil can restore consistency.

Proper seal paste usage ensures the best final work. Check thickness, color, and match with your calligraphy to avoid mistakes. Remember, seal paste is essential to highlight your artwork. Practice diligently!
