You should not. That's the last day the maker expects it will work perfectly.
It can be just fine, but how much work do you want to lose if it's not? How will you know if it didn't expand right or adhere to itself well enough until you've done it all?

I’d use it. They put expiration dates on stuff because it’s required. Do you really think porcelain powders or lab plaster change with time? Yeah, me neither...

I hope to live past my best before date.

I would use the investment if it has been kept according to instructions. On the other hand, I would hesitate to use the liquid past it's expiration date, or more specifically, I would use it expecting less than perfect results.

I mean especially for phospate bonded investment, like for pressing and for refractory

I have some vintage 2019 that still works fine.

Is it a bit bold, or pretentious, with a bit of woody undertones and a hint of fruitiness? Does it go better with chicken or beef?

a hint of fruitiness?

My dad once described most singers this way.
