I currently have to use a pot holder to check on my chile, etc.
HACK a POT-LID KNOB COZY
If you have a single heavy sock from an evil washing machine that stole its mate, cut off the toe and slip it over the protruding knob. The knob will hold the sock toe cozy in place during your meal preparation.
No more dealing with the oversize separate pot holder.
Typically these glass lids are mounted with a single bolt through the glass to the knob. I'd unscrew that, remove the knob, and in its place mount a piece of wood with a reasonable shape to use for a knob. So, spherical or cylindrical would be good for a start.
To mount it, I'd pre-drill a small diameter hole and then use a stainless steel wood screw (spax screw; or technically a "cross recess countersunk head spaced thread screw"). Take care to use the original washer that was mounted on the inside, and take care to not create any force on the edges of the hole that goes through the glass – that could make the glass lid break.
