Master Alchemist + Beaker of Plentiful Poisons

[Ian Meadows]

Both the Master Alchemist Feat from the Advanced Players Guide and the Beaker of Plentiful Poisons from Pathfinder Unchained, allow you to use the gp value of poisons instead of the sp value when crafting. So, if you have both, does it act as a further 10x manufacture rate for the doses you are making with the Beaker, or do you just not gain a benefit from that ability of the item since you already can do that due to the aforementioned feat?

I think that RAW the speedups don't stack, but I'd probably let them stack because the normal crafting times are way too long.

The mundane crafting rules are broken anyway, so what I'd do is just make craft(alchemy) work at the same rate as potions: up to 1,000 gp worth of poisons per day of work, or 2 hours if the total cost is 250 or lower.

Looks like they stack, I found a Paizo prestige class that has an ability that gives them the same bonuses as Master Alchemist and it says that if you also have that feat, you can craft 2x Int bonus poison doses at a time and you use the PP value of the doses to determine progress.
