紫砂泥中的传说：天青泥、黑星砂，到底是何方神圣？还买得到吗？

看到这个标题，想必大家都知道今天我们要一起分享的话题了吧~是的，就是紫砂圈的泥料传说，天青泥和黑星砂。这两款泥料可以说是很多玩壶人都魂牵梦萦的泥料，甚至很多玩壶人毕生都在追求这两款泥料的紫砂壶。那么，到底这两款泥料有何神秘之处，又有何种前世今生呢？我们接着往下看~
天青泥
在古籍《宜兴县志》有记载：“土有青黄，用供抟埴。天青泥于诸泥为贵，制茗壶者特用之，黄泥供缸瓮坯之。”简单一句话，就说明了天青泥的精贵！
历史上，天青泥出产自黄龙山的蠡墅矿区，也就是现如今我们经常听到的“大水潭”。我们来看一下天青泥的矿料：产于青灰紫泥之下，紫中带红，块状致密，质地均匀，易碎稍显坚硬。
明代周高起《阳羡茗壶系》说：“天青泥，出蠡墅，陶之变黯肝色。”所以，天青泥烧成后一般来说呈暗肝色，但是会随着窑温的变化而色泽出现变化。下图的这把杨凤年的《风卷葵》作品就是天青泥作品中比较出名的一把，现被收藏在紫砂博物馆内。
其实，我们不难发现，你去网上收罗天青泥，铺天盖地的“绿”壶展现在你面前，很多人都觉得既然叫天青泥，那必然是青色或者是绿色的，所以市场的“绿”壶一度来说非常热门。可是偏偏天青泥说到底归属于紫泥类目，色泽在暗肝色游离，你觉得那些绿壶还靠谱吗？
我遇到过很多壶友张口就问：现在还能买到天青泥的紫砂壶吗？答案肯定是不能！早在清末天青泥就已然失传，如今可见的天青泥作品也只能在博物馆找到了~
黑星砂
黑星砂也称黑星土，有一段时间在紫砂市场上也是非常热门。那么它到底是原矿泥料还是认为拼配而成呢？在早期，紫砂界确实存在着原矿的黑星土料，它的黏性佳，含铁量高，烧成之后壶身会呈现很多密集的小黑点，这也是黑星土的显著特征。
但是，单一的原矿黑星土产量实在太少了，所以后来紫砂一厂的老艺人拼配出了黑星土这款料。他们是通过添加天然锰粉来调配黑星土泥料，所以千万不要把老一厂的黑星土料归结到化工料这一类。毕竟，天然锰粉的添加历史古来有之。现在市场上常见的黑星土紫砂壶大多以添加金属氧化锰为主，对于新入门的壶友来说还是不碰为好。
这两款紫砂泥料是紫砂界的传奇料，很多人特别好奇。但是好奇归好奇，先来了解一下这两款泥料的前世今生，再去想想到底要不要上手！好了，今天的分享就到这里，下期我们接着聊~
Legend in Zisha Clay: Where are the sacred TianQing Clay and Black Dotted Clay? Can you still buy it?
The artist Liu Hao
Seeing this title, I think everyone knows the topic we are going to share today~ Yes, it is the clay legend of the purple sand circle, Tianqing clay and black star sand. These two clays can be said to be the clays that many pot players dream of, and even many pot players have been pursuing these two clay teapots all their lives. So, what is the mystery of these two clays, and what kind of past and present? Let's look down~
TianQing Clay
There is a record in the ancient book "Yixing County Chronicles": "The soil is green and yellow, and it is used for tuan. Tianqing clay is expensive in all kinds of clay, and it is specially used by those who make tea pots, and yellow clay is used for cylinder urns." It shows the exquisiteness of Tianqing Clay!
Historically, Tianqing clay was produced in the Lishu mining area of Huanglong Mountain, which is the "big water pool" we often hear nowadays. Let's take a look at the mineral material of Tianqing Clay: it is produced under the green gray and purple clay, with reddish in the purple, dense lumps, uniform texture, fragile and slightly hard
Ming Dynasty Zhou Gaoqi’s "Yangxian Tea Pot Series" said: “Tianqing green clay comes out of Lishu, and Tao Zhi becomes dark liver color.” Therefore, after the Tianqing clay is fired, it generally has a dark liver color, but it will change with the temperature of the kiln. The color changes and the color changes. The picture below is Yang Fengnian’s "Wind Rolling Sunflowers" work, which is one of the more famous works of Tianqing clay, and is now housed in the Zisha Museum.
In fact, it is not difficult for us to find that you go to the Internet to collect Luo Tianqing clay, and the overwhelming "green" pots are displayed in front of you. Many people think that since it is called Tianqing clay, it must be blue or green, so the market's "green" "The pot was very popular at one time. But the sky green clay belongs to the purple mud category after all, and the color is in the dark liver. Do you think those green pots are still reliable?
I have met a lot of pot friends and opened their mouths and asked: Can I still buy a purple clay pot from Tianqing clay? The answer is definitely no! The Tianqing clay was lost as early as the end of the Qing Dynasty, and the Tianqing clay works that can be seen today can only be found in museums~
Black Dotted Clay
Black Star Sand is also called Black Star Soil, and it was also very popular in the purple sand market for a while. So is it raw ore clay or is it made of blending? In the early days, the black star soil material of the original ore did exist in the purple sand world. It has good viscosity and high iron content. After firing, the body of the pot will show many dense small black spots, which is also a significant feature of the black star soil.
However, the output of a single raw ore Black Star Soil was too small, so later the old artists of the No. 1 Zisha Factory assembled this material of Black Star Soil. They use natural manganese powder to mix the black star soil clay, so don't put the black star soil from the old factory into the category of chemical materials. After all, the addition of natural manganese powder has a history of ancient times. Most of the common black star soil purple clay pots on the market are mainly made of metal manganese oxide, so it is better not to touch them for newcomers.
These two purple clay clays are legendary materials in the purple sand world, and many people are particularly curious. But curiosity returns to curiosity. Let's first understand the past and present of these two clays, and then think about whether to use them! Okay, that’s all for today’s sharing, and we will continue to talk in the next issue~
