Glass Teapot and KettleAn all in one tea tool this glass teapot can go directly onto your stove to warm the water. Place your tea leaves inside to steep and then pour as the spout filters out the tea leaves. Great especially for cold brewing and multiple brews, the tea pot can hold up to 60 fluid ounces or at least 7 cups of tea and can be used on both gas and electric stoves. Tisanes with small leaf ingredients like rooibos may require additional filtering.
