Glass instruments with sand core should avoid sudden temperature changes, especially when placed in an oven for drying. It is essential to place them in an oven at room temperature before increasing the heat, and not to put them directly into a high-temperature oven. When removing them, wait until the oven has cooled to room temperature before taking them out.
