No, you should not microwave glue gun sticks. Glue gun sticks are typically made of thermoplastic materials that are designed to melt and flow when heated in a glue gun. Microwaving them can cause uneven heating and may result in the sticks melting too quickly or even catching fire.
Microwaves are not intended for heating or melting solid materials like glue gun sticks. It is best to use a glue gun specifically designed for melting and dispensing glue sticks. These glue guns provide controlled and even heating, ensuring the glue sticks melt properly without any safety hazards. Always follow the instructions and recommendations provided by the manufacturer of your glue gun to ensure safe and effective use.
