I just did my first partial mash.
For a 2 gallon batch, I did the folowing:
Mashed 500g pale malt with 200g crystal malt for 1 hour
added 1kg malt extract boiled with hop schedule for an hour
topped up water to 2 gallons
During the boil, I didn't see any protein come to the top.
I took a gravity reading and it was 1060 (at the correct temperature), about 4 points too high. I was wondering if sediment would contribute to the reading? After about 10 minutes there was a bit of sediment at the bottom of the trial jar...
