Everytime I use a puck of soap, I mark it down. When the puck is gone, I can therefore tell exactly how many shaves I got out of it.
The amount of shaves from a puck of soap can vary a great deal from one soapmaker to another. The following were my totals for a few different soaps (YMMV):
Dr. Jon's Hydra lasted me 46 shaves.
I Coloniali lasted me 34 shaves.
Cold River Soaps Select Citron I acquired used but it appeared nearly new; it was gone in 34 shaves.
B&M's Latha in the Limon scent was gone in 33 shaves.
Now that I look at this list, they are closer to each other than I thought. But I am currently 38 shaves into a puck of Stirling and it is only between 1/4th and 1/3rd gone. These pucks are larger too (in weight), being almost 6 oz.
I also had a puck of Country Club for Men in the Orange Blossom scent that lasted me at least 108 shaves (I gave a pretty good sized portion of it away, and finished the rest in 108 shaves. This, too, was a 6-oz puck. I'm guessing that the portion I gave away was good for about 8-10 shaves, which would put it close to 120 shaves. Even for 6 oz, that's a lot more than the above-named soaps (would expect 90 shaves from a 4 oz puck, which is more than twice as much as any of the 4 I listed).
The I Coloniali may be smaller than 4 ounces.
Have you noticed a soap that lasts longer for you, or seems to disappear faster?
