5 Things to Know About Glass Mousepads and Mouse Feet Wear

Hard glass mousepads wear down PTFE feet faster than other surfaces The tempered hardness of glass is smoother but also more abrasive at a microscopic level, acting like very fine sandpaper against soft PTFE plastic.

You will see wear marks on PTFE feet within weeks on a standard glass pad PTFE is soft and sacrifices itself to glide smoothly, so regular use on glass causes noticeable wear quickly.

Super-hard tempered glass pads still wear down PTFE, just slightly slower Fewer microscopic peaks on ultra-smooth glass reduce the abrasion, but the wear still happens over time.

Ceramic feet last much longer on glass because they are closer in hardness Ceramic does not wear down nearly as fast as PTFE, making it a durable choice for glass pads.

Ceramic feet can feel scratchier and louder on glass The tradeoff for longevity is a different feel, as grinding two hard surfaces together produces more noise and friction.
