title: "Do You Need Heat-Resistant Glasses?"
lead: "If you ever pour hot drinks into glass, yes — regular glass is a cold-drinks tool, and boiling water can crack it outright. One pair of borosilicate (heat-resistant) glasses covers tea, hot lemon water, and the microwave; your existing glasses stay on cold duty."
recommendation:
  name: "A pair of borosilicate glasses for hot duty — regular glass stays cold-only"
  reason: "Regular soda-lime glass tolerates only a modest temperature swing, so boiling water into a room-temperature glass is a coin flip you eventually lose. Borosilicate barely expands with heat: it takes boiling water and the microwave, and the label says so — look for 'heat-resistant' or a stated temperature-difference rating. Don't confuse it with tempered glass, which is tough against knocks, not against heat. Buy the heat-resistant pair when hot drinks actually land in glass at your table; mug drinkers can skip this entirely."
