You can simmer chenpi in a glass kettle, but use heat‑resistant glass and avoid thermal shock. Here are practical tips.
1. Choose Heat‑Resistant Glass
Use kettles labeled as heat‑resistant or borosilicate glass and follow the manufacturer’s instructions.
2. Avoid Sudden Temperature Changes
Do not rinse with cold water right after heating or pour in very cold liquids.
3. Prevent Dry Boiling
Keep enough water in the kettle to avoid local overheating.
4. Check for Damage
Stop using the kettle if you see cracks or signs of aging.
With proper equipment and handling, simmering chenpi in glass is generally workable.
