Double porosity structure: The most characteristic quality of Zisha

After the Zisha mud is fired at about 1 100℃ ~ 1 200℃, the aggregates in the mud still exist, but the particles such as quartz, mica remains and mullite crystals formed inside are increased. Microscopic analysis shows that there are small and large pores between these aggregates and some of them. This is the so-called "double porosity structure" in purple sand facies.

1.Chain stomata

The chain pores are generally surrounded by the original aggregates. The width of the pores is less than 20 μ, the narrow pores are less than 10μ. The length of the extension varies, some through, some intermittent

2.Micropore

Micro-pores are micro-pores in irregular shape formed by different shrinkage during the firing process between the minerals inside the aggregate. There are two kinds of opening and closing mouths, and the size is generally between 1 ~ 3μ.

The heat dissipation of tea is even, transparent without leakage, and the tea keeps fresh.
