玻璃壶

观看水的苏醒 — 从寂静到沸腾

硼硅酸盐玻璃揭开了百年来隐形的仪式面纱。当热能穿过玻璃,沸腾的每个阶段都成为感官的停顿 — 鱼眼、蟹眼、一串珍珠 — 帮助你抓住茶叶所需的精确温度。无金属、无涂层,只有水与火焰完美呈现。

为什么硼硅酸盐壶值得在茶厨房占一席位

硼硅酸盐玻璃于二十世纪初作为实验室新奇物登场——耐热、化学惰性、耐冲击,足以从火炉移至冷却台而不破裂。茶人很快意识到科学家早已知道的事:透明就是控制。当你看不见水,就错过了热与茶叶之间的对话。玻璃壶将这对话变成可见的弧线。中国茶传统为沸腾的各阶段命名——虾眼(70–80 °C)、蟹眼(80–85 °C)、鱼眼(85–90 °C),以及滚沸时的一串珍珠(95–100 °C)。每一种水温为不同的茶类解锁:蟹眼适合绿茶,鱼眼适合乌龙,全沸适合普洱茶。除了温度,玻璃拒绝在水中化学留下指纹。不锈钢可能轻微改变pH值;玻璃则保持中性。这在你从头开始调配水质或调校一款细致的白毫银针时就很重要。前往 thetea.app 的「泡茶水」百科条目阅读完整的化学故事,或加入我们 tea.school 的「第六味——水」课程,了解溶解气体与矿物质如何形塑每一泡茶汤。制作我们这些壶的柳州工坊以手工打造硼硅酸盐,塑造出可在瓦斯炉、电磁炉(需用扩散板)和电热线圈上平稳摆放的圆壶。轻盈但坚固,这些壶从炉灶移动到工夫茶盘上,带着一种一辈子专注做好一件事的工具才有的宁静自信。

来自柳州工坊——三种容量,应付每一种火源

每一把明火用硼硅酸盐壶均由 Gao Liuzhou 手工成形,这位玻璃吹制师的工作室坐落在广西的石灰岩山峦之间。简单、真诚、沈静之美。

A buyer's note

Choosing your glass kettle — a buyer’s checklist

硼硅酸盐玻璃,非普通玻璃

Look for high thermal shock resistance. Borosilicate can handle stove heat and quick cooling without cracking, unlike tempered soda-lime glass.

手柄人体工学

An angled, heat-resistant cork or bamboo handle keeps your hand away from the spout and balances the kettle when pouring.

盖子密合度

A well-fitted lid with a small vent hole prevents steam spurting and keeps the boil visible without dancing off during a rolling boil.

电磁炉兼容性

If your stovetop is induction, confirm the kettle works with a diffuser plate or look for a model with a steel base insert.

壶嘴出水

A narrow, curved spout gives gongfu-level control. A wider spout suits everyday brewing but sacrifices precision.

清洁与保养

Use soft sponges and a vinegar rinse to remove water scale. Avoid sudden cold-water shocks while the kettle is hot.

Common questions

Asked, answered.

Can glass kettles go on a gas stove?

Yes, all our borosilicate kettles are designed for direct gas flame. Use a diffuser plate if the burner is very small to distribute heat evenly.

Will a glass kettle work with an induction cooktop?

Glass alone does not heat on induction, but you can use a stainless steel diffuser disc under the kettle. Some models have a steel base for direct induction use.

Does boiling water in glass affect the taste?

Glass is chemically inert and leaves no metallic aftertaste. It’s one of the few materials that won’t alter water’s pH or texture.

How do I clean mineral buildup inside the kettle?

Fill with equal parts white vinegar and water, bring to a gentle boil, let sit 20 minutes, then rinse thoroughly with soft water.

What’s the best size for gongfu cha?

The 0.8L kettle is ideal for solo or two-person gongfu sessions; 1.2L covers a small gathering without constant refills.

Is borosilicate glass breakable?

Borosilicate is highly resistant to thermal shock, but it’s still glass. Avoid dropping it and don’t plunge a hot kettle into cold water.

Can I leave water in the kettle overnight?

It’s fine for a day, but regularly emptying and air-drying the kettle prevents water stains and keeps the spout clean.
