(3) Glass instruments with sand cores require careful handling to avoid sudden temperature changes, especially when being dried in an oven. Always place them in an oven at room temperature before increasing the heat; do not directly place them in a high-temperature oven. When removing them, wait until the oven has cooled to room temperature before taking them out. Otherwise, due to the different thermal expansion coefficients of the sand core and glass wall, they are prone to cracking.
