This is regarding a 10Gal batch of partial grain. If I was going to do a
10Gal batch, I need a pot where I can boil up to 6 gallons of wort at a
time correct?
I see people looking for 15 gallon pots to do 10Gal batches, but dont
you really need a 10Gal pot for 10Gal batches since you will only boil
6Gals at a time?
Am I missing something or are they talking about all grain?
Thanks,
Jim

They're talking about all grain where you boil the entire batch at once,
plus enough extra to account for losses. IOW, a 10 gallon all grain batch
would boil something like 12+ gallons. That's why you need a 15 gallon
kettle, including enough room that you don't have a boil over.

It's not all-grain per se, it's doing full boils. So
if you don't plan to top up after the boil, you'd need a
container big enough to contain your final volume plus
the volume that evaporates during the boil, plus a bit
of extra head space to help stave off boil-overs.
Brewing from grain *generally* means doing full boils
due to the (again, usually) dilute wort that you get from
the lauter tun.
One might want to do full boils even when brewing from
extract in order to get better hop utilization, to prevent
kettle caramelization and/or wort darkening, and to not
have to deal with getting sanitized water to top up with.

If you're doing a 5 gallon all grain batch you'll need to be able to boil
about 6.5 gallons. So a 10 gallon batch should take around 13 gallons.
Unless of course you intend to top off with plain water, then you would
boil less, but that's mostly for extract brewing. I do 5 gallon batches
and I boil just about 6 and a half gallons. I lose about a gallon an hour
during the boil and I lose about a quart to the pot. That added to what's
left behind in the primary and I end up with just over 5 gallons when I'm
done.
