Not to derail the suggestion of the soap growing (I seem to observe this!) but I think the Kent soap might be mislabelled. I presume it's 125g like how Mitchells advertises. So on the grounds it was 125g to begin with and you used approximately 4g of soap for 14 shaves, that still on course for the puck sorry cake of soap to last for 300 shaves or more.
I think I've used my one for somewhere between 50-75 shaves, and I've just about made a dip on the top. I think I've used about 1/6th of it as the most. I've been using it with large brushes and loading heavy as well, I'm sure if I really wanted to I could stretch it out even more!
Seems to be incredibly good value all things considered.
Good to hear you have some ones from a good batch.
Using The Fat entirely for this month, I've not missed my other soaps as much as I thought, but I'm looking forward to using some other things, in particular Signature Soaps.
I was thinking closer to the time to suggest a themed month 'Artisan April'. I imagine it won't require much of a change for many here, but for others like myself who seem to favour the classics, it could be a good way to give some attention to the independent soap producers.
But for now,
ALL HAIL THE FAT.
