Surprising Glass Teapot Tested: Safe for Cold Brew & Hot Tea

When it comes to brewing tea, the humble glass teapot often takes a backseat to its stovetop or electric counterparts. But a recent test revealed that some glass teapots are more than just elegant vessels-they're surprisingly versatile, capable of handling both hot tea and cold brew with equal finesse. Let's dive into how these contenders stack up, from sleek electric kettles to traditional stovetop designs and even artisanal cast iron.

The Cosori Electric Kettle (1.7L, 1500W) impressed with its modern efficiency, offering automatic shut-off and a stainless steel inner lid to prevent scorching. While it doubled as a hot water boiler for coffee and tea, its glass design tempted users with a clear view of the liquid, but it lacked the thermal stability for cold brew.

In contrast, the HIWARE 1000ml Glass Teapot with removable infuser and stovetop safety proved a more balanced choice. Its borosilicate glass, durable and heat-resistant, was perfect for both hot infusions and cold brewing, while the included removable infuser allowed for adaptable use. A PARACITY 18.6oz Glass Teapot echoed this with its clear borosilicate construction and spacious 18/8 stainless steel infuser, ideal for travelers seeking a compact yet functional brewer.

For those preferring a classic touch, the Suyika Japanese Tetsubin cast iron teapot with enameled interior and stainless steel infuser offered exceptional heat retention and a retro aesthetic. However, its weight and slower heating made it less practical for quick cold brews. Meanwhile, the Ehugos 1500ml Glass Teapot, designed for blooming and loose-leaf brewing, combined durability with a stylish, transparent body-though it catered more to those who appreciate artisanal craftsmanship.

Ultimately, the SUSTEAS Stove Top Whistling Kettle, despite its stainless steel construction, stood out for its user-friendly design, including a cool-touch handle and silicone mitt, making it a favorite for both casual sipping and more intentional brewing. Yet, the HIWARE and PARACITY glass teapots emerged as frontrunners for their seamless adaptability, proving that color, heat, and brewing method don't have to be at odds.

Whether you're after speed, tradition, or a touch of whimsy, the right teapot can transform your ritual-especially when glass is the unexpected hero.
