What makes the infuser on this mug better than typical tea balls?
The infuser is notably deep and spacious, giving tea leaves plenty of room to expand and steep properly—something reviewers specifically called out as superior to cramped tea balls. The mesh is fine enough to catch even small tea particles, so you won't get those annoying bits floating in your cup. Plus, it sits perfectly in the mug without wobbling around, making the whole steeping process cleaner and easier.
Can I actually put this in the dishwasher and microwave?
Yes, it's genuinely dishwasher and microwave safe, and reviewers confirm it holds up well to both. The ceramic construction handles the heat without issues, making cleanup effortless and reheating convenient. Just note that the bottom surface is unglazed and slightly rough, so you might want to use a coaster to protect delicate surfaces.
Is 13.5 oz enough for a full tea session?
It's a solid size—about a mug and a half of tea, which most people find perfect for a single sitting. It's large enough to feel satisfying without being so big that your tea gets cold before you finish. The generous capacity also means the deep infuser has plenty of water contact for thorough steeping.
What's the deal with the reactive glaze finish?
The reactive glaze creates subtle color variations and a unique, artisan look that makes each mug slightly different. Reviewers consistently mention how beautiful the finish is, particularly in the Deep Blue color. It adds an elegant touch that elevates this beyond your typical tea mug, though it's worth knowing the finish is more about aesthetics than affecting the tea itself.
Does the lid actually keep tea warm, or is it just decorative?
The lid genuinely helps retain heat during steeping and keeps your tea warmer longer between sips. As a bonus, it doubles as a convenient coaster or saucer for the infuser once you remove it—a thoughtful design detail that reviewers appreciate. It's functional, not just for looks.
Is this good for someone new to loose leaf tea?
Absolutely. This is an ideal starter setup because everything you need is in one piece—no hunting for separate infusers or dealing with messy tea balls. The infuser sits securely in place, it's dishwasher safe for easy cleanup, and you can actually see your tea steeping through the lighter areas of the glaze. Several reviewers mentioned it made switching to loose leaf tea much less intimidating.
