Why Tempered Glass Spontaneously Bursts and Preventive Methods

Many homeowners and bulk purchasers encounter unexpected spontaneous bursting of tempered glass lid during daily cooking, which is one of the most frequent worries when using standard glass pot lid. Understanding trigger factors helps users effectively protect their cookware glass lid and extend service life.

Nickel sulfide impurity inside raw glass is the primary cause for self-explosion of kitchen glass lid. Tiny sulfide particles expand unevenly under temperature change, breaking internal stress balance of the tempered universal glass lid and leading to sudden cracking without external collision. Improper installation and extrusion from silicone rims also squeeze the edge of the glass lid to trigger bursts.

Several practical measures can cut self-explosion risks of your glass lid. Choose qualified certified tempered glass lid with complete production inspection. Avoid sudden extreme hot-cold pouring on the cookware glass lid while cooking. Leave proper gap between silicone seal and glass edge to prevent long-term squeezing stress.

Selecting high-standard tempered glass lid remains the most fundamental solution to avoid unnecessary kitchen accidents caused by spontaneous breakage.
