Once upon a time I foolishly used a very heavy pot atop my glass top stove.
Oh, I was careful to not drop it on the glass top. Instead I dropped it on the corner of the stove, creating a chip in the white porcelain the size of a dime.
THEN! I read in a magazine (can't remember which) that I could repair that chip with a little bottle of white stuff...sorta like that little bottle of white-out we used to use at the office to cover typos. Only this stuff is for appliances. So I jotted down the info and headed for the hardware store.
The product is Appliance Epoxy Touchup by Rust-oleum. You can find it in the appliance department.
I put on a couple layers, letting the epoxy dry between coats.
The resulting repair is almost invisible. This little cover-up job was well worth the $5 I paid for the bottle.
I no longer covet Le Creuset ware. No, indeedy. I'll stick to my lighter weight pots and pans and leave the heavy-duty stuff to heavy-duty cooks.
P.S. White on white is difficult to photograph. The area is still visible to the naked eye if one looks closely. But the repaired area no longer catches my eye every time I look at the stovetop.
