Food grade stainless steel general gloss good, smells without heavy metal rust.
High borosilicate glass filter kettle is technically more demanding, with stainless steel filter kettle on market dominant, glass filter kettle does not see more, so don't believe the glass filter kettle, with a less known and inferior brand on the market can choose such as bear electric equipment of high borosilicate glass filter kettle, in the network can query to the relevant manufacturers, brand information and after-sale service is relatively better.
Glass in high heat-resistant borosilicate glass and the instantaneous temperature performance requirements, under the condition of temperature sudden change does not happen in an instant burst phenomenon, its in weight compared to contain a large amount of heavy metal ions' raw glass is much lighter, there are differences in appearance looks like common glass, the vision from the 'raw glass' feeling of hard and brittle.
Some still using silica gel firmly stick to the glass bottom of the pot body, filter kettle 5 minutes after turning on the power supply, water vapor bimetallic strip deformation of steam heat element, switch contact up to disconnect the power supply.
If the steam switch failure, in POTS of water would have been burned down, until the water is dry up, a sharp rise in the temperature of the heating element, located at the base of the heating plate has two bimetallic strip, because heat transfer temperature rise sharply, expansion deformation, disconnect the power supply.
Glass in my hand is in order to more convenient to remove and replace the glass pot body, on the other hand can also achieve leakproof effect, high temperature resistant effect, but also conform to the hygiene standards.
We usually use the kettle will precipitate a long period of time some scale in the bottom of the kettle, because the problem of water quality, especially the hot kettle of boiling water express, the more the kettle bottom sediment dirt.
Now on the market of filter kettle basically USES is high manganese steel and 304 of these two kinds of stainless steel material, high manganese steel material made of filter kettle, after high temperature heating, heavy metal material such as dissolution of manganese, often drink this kind of material to burn out of water, can cause certain harm to the body.
The 304 stainless steel material is by far the most popular, not only high temperature resistant, and processing performance is good, use the burn out water safe to drink.
Glass in we all know that scale is very difficult to remove, because sediment contains calcium carbonate and other chemical substances, and some chemical elements in the water, if the kettle of sediment accumulation is overmuch, time grows, will seriously affect the family's health.
