Almost anything will burn if it gets too hot.  The most common reason for burned flowers, pads and liners is a pressing time that is too long.  If you mean to put the press in for an additional 20 seconds and type in 200 (more than 3 minutes) by mistake, your pads will likely burn.  Always lightly mist your pads before starting (you can also wet your hand and rub it on your pads). Never leave a press in your microwave unattended.  The pads are wool and will emit a bad odor when scorching.  Should you smell this odor, open your microwave door immediately. Use caution removing the press as it may be hot.  Our presses are meant for adults and children should not use them without supervision.  That being said, when directions are followed, burning pads is not a normal occurrence.  Should you burn your liners and pads, you may easily order replacements on here or from any of our retailers.
