How we evaluated it
Why we chose it What put it on our list
- Hario names the material of every part: heatproof (borosilicate) glass for the pot and lid, and stainless steel for the strainer.
- The image description on Hario’s page says the lid and handle are glass as well, with a metal mesh basket. No plastic part is listed.
- Hario states the origin by part: glass made in Japan, strainer made in China. A UK retailer, Borough Kitchen, gives the same split.
- At $28.50 for 450 mL it costs about the same as Rishi’s Simple Brew pot, and Hario’s page carries no Prop 65 warning. We found no Prop 65 notice naming Hario.
Trade-offs What to weigh before you buy
- The materials and origins are Hario’s statements. We found no outside lead or cadmium test of this pot, and the page does not mention any printing or decoration on the glass.
- It is for hot water only. Hario says it is safe for the microwave (with the strainer removed) and the dishwasher, and not for ovens, induction hobs or open flame. Borosilicate glass still breaks if dropped.
- The strainer is made in China, so it is the one part not covered by the made-in-Japan claim.
- Hario also sells ChaCha pots with a plastic strainer (the Natsume). Check the product name and the materials line before you buy.
What to know Details worth knowing first
Hot water on loose leaf, in a pot with no plastic, is the simplest way to avoid the microplastics that some tea bags shed (see loose leaf vs. tea bags). This Hario pot has a borosilicate glass body, lid and handle and a stainless-steel basket, and its maker lists no plastic part.
We chose it over Rishi’s popular Simple Brew pot because Hario says where each part is made, and nothing about its listing raises a lead flag. Rishi’s pot has the same materials on paper, but its own page gives no country of origin and no lead statement.
That is still the maker’s word. On any glass teapot, look for printed or painted decoration. Lead Safe Mama, an advocacy group, reported in 2022 that a glass teapot brand had removed lead-painted logos after its community raised the issue. Plain glass avoids the question. For lead in glazed pottery, see lead in cookware and food.
Quality & testing How it measures up against our checklist
| What we checked | What we found |
|---|---|
| Teaware you can name Maker’s claim | Pot and lid: heatproof (borosilicate) glass. Strainer: stainless steel. Rishi’s page for the same pot lists the same materials. |
| Plastic-free Maker’s claim | No plastic part is listed, and the image description on Hario’s page says the handle and lid are glass. We have not handled the pot. |
| Country of origin Maker’s claim | Glass made in Japan; strainer made in China. Borough Kitchen’s product page gives the same split. |
| Lead statement Not verified | Hario makes no lead statement, and none is usual for plain glass and steel. We found no outside lead or cadmium test, and the page describes no decoration. |
| Notices and recalls Verified | We found no California Prop 65 notices and no CPSC or FDA recalls naming Hario when we searched on 22 Oct 2026. |
What the labels mean
- Verified We opened an independent record that confirms it: a certifier’s listing, a regulator’s list or a lab report. It is linked under Sources.
- Maker’s claim The maker says so on its own page or label. We read it but found no independent record.
- Not verified We looked and could not confirm it, or the maker does not say. Treat it as unknown.
