For when it arrives
Your glass lid travels with the knob detached to keep the tempered glass safe. Putting it back together takes about a minute — six pieces, five steps, one screwdriver.
Know the pieces
Lay them out before you begin. Each has a role — together they cushion the glass and lock the knob in place.
The flared bell you grip to lift the lid. It threads onto the screw and sits on top.
A flat steel disc under the knob that spreads its grip evenly across the glass.
A thin soft disc on top of the glass. It cushions the glass and blocks heat from the knob.
The tempered-glass lid itself, with a single hole at the centre for the screw.
A small soft washer for the underside, between the glass and the screw's ring.
The single fastener. It goes up from underneath and threads into the knob to hold it all.
Put it together
Work on a flat, padded surface — a folded tea towel keeps the glass steady and scratch-free.
From the underside, push the screw up through the hole in the centre of the glass, with the white rubber washer between the glass and the screw's ring.
Turn the lid to its top face. Drop the red silicone gasket over the screw so it lies flat on the glass.
Lay the silver plate on top of the red gasket, centred over the screw so it sits level.
Thread the steel knob onto the screw and turn it down by hand until it stops.
Hold the knob and tighten the screw from underneath with a Phillips screwdriver until firm. Give it a wiggle — solid means done. Snug, not forced, the glass is tempered.
The idea
One screw does all the work. It runs up through the centre from below and threads into the knob at the top. As you tighten, the knob and silver plate are pulled down onto the glass while the ring and white washer press up from underneath — clamping the lid in the middle.
The red gasket and white washer sit on either side of the glass, so metal never touches it directly.
If the knob ever works loose, a quarter-turn of the screw underneath is all it takes. Let the lid cool first.
Keep it right
Tempered glass dislikes over-tightening. A quarter-turn too far is the only way to crack it.
Wait until the lid reaches room temperature before you loosen or remove the knob to wash it.
Give the knob a quick wiggle-test every few weeks and nip the screw up if there is any wobble.
Hand-wash and dry the knob and gasket to keep the steel bright and the silicone supple for years.
