I remember reading about some high tech super smooth glass being developed that tomato sauce glides right over.

Then around the same time the sauce industry switched over to squeezy plastic bottles that solve the problem of no sauce coming out of the glass bottle until you give it a few whacks and it all comes out at once.

But they also introduced the problem of any amount of crusty sauce on the nozzle makes a jet stream of sauce eject in a nominally random direction that allways ends up on your shirt.

Where are the magic glass sauce bottles we were promised?
