1. Is purple pottery pot easier to crack in winter?
A: the ambient temperature in winter is lower than that in summer, but for the same place, whether in winter or summer, the temperature when boiling water boils is the same, because the altitude has not changed. Therefore, the impact of boiling water on a pot is greater in winter than in summer. From this point of view, the purple pottery pot is more likely to crack in winter.
But to discuss whether a teapot will crack or not, we should also consider the temperature range of the teapot. In fact, the temperature of a place changes at any time, that is to say, the teapot is subject to the impact of temperature change at any time, but very few teapots are shocked. It is only when the temperature suddenly changes greatly beyond the bearing range of the teapot that it will crack.
From the perspective of the situation of people, whether it is purple pottery or purple sand, the change brought by boiling water temperature can be borne by teapots, only a few will be shocked and the probability is very low. Therefore, although purple pottery pot is more likely to be cracked in winter, we can use it safely; if you know to warm the pot in advance, it will be better.
2. Is it good to make wood vitrified?
A: This is a question of opinion and wisdom. I say three points of view:
First, in terms of the effect of firewood firing, it is undoubtedly very rare if the natural gray glaze of a firewood burner can produce vitrified texture, or even produce ice flakes like Ru porcelain or ice crack effect like GE kiln without crack glaze.
Second, from the point of view of tea ware, the permeability of vitrified wood burner is relatively low. Although the air permeability is not completely lost, it is at least decreased. This is not a good tea set for some tea friends who pursue good air permeability.
Third, in terms of personal preference, some people like the light fire trace and light glaze effect, while others like the heavy glaze effect which is black and thick and turbulent everywhere. It’s not about good or bad, it’s just personal preference.
