This morning I opted to use the Sorrentino TSC Barzini brush again, as I enjoy learning optimal application of any tool. Yesterday I commented that the shake of the brush into the soap dish to bloom the soap resulted in significantly less water than what my 26mm Finest Badger provides, but on the other hand, the amount of soap loaded onto the TSC brush is less as well. Today when I dipped the brush in the sink and got ready to shake it in the soap dish, I did not allow it to gravity drain as long. The result was there was more bloom water which is what I was going for, but not as much as I typically get from the Stirling brush. After dispensing the bloom water into the scuttle. my normal routine is to shake the brush dry, then load the brush. I must say that the badger brush holds a lot more residual water even after a fairly rigorous shake when compared to the TSC Barzini, hence, the reduced surface area of the knot along with not having as much water retained in the brush results in less soap being loaded onto the brush compared to the 26mm badger. Less soap plus less water then makes perfect sense when trying to get the water:soap ratio right. It all was making sense. When using the Stirling knot, I always have more lather than required to do a three pass shave, in fact two or three people could probably do a 3 pass shave.
This morning I made an observation though. When I started building the lather, everything was coming together as normal as the loaded soap began to dissolve completely in the bloom water, making it milky white. As i continued to work it it soon started developing into a lather as I always do. Then when the lather is such that it wont come slopping out of the scuttle, I start a more rigorous whipping to finish the build. What I found out is that the resulting lather definitely has different properties than does the same lather whipped with the Stirling brush. When I did the final brush load just prior to going to the face, I noticed that the lather had pronounced points when removing the brush from the scuttle. This never happens with the Stirling brush right after making the lather. With the Stirling I would characterize the points as being soft points, and I typically do have to work the brush quite a bit on the face with the initial application. With the TSC Barzini, the lather was perfect as it was, and it was simply a matter of applying it and relishing the softness of the bristles and the warmth of the lather. On the second pass, I did add a little more water by dipping the brush slightly into the hot tub. After working the lather a little, the points on the brush were just as pronounced and sharp as they were the first time. I went through the same process adding a bit more water for the areas that I perform a third pass on, and the result was the same. With the Stirling I never add any more water, and typically the points do not become pronounced in the lather until the second and third pass, which I have always interpreted as being a result of evaporative water loss in the lather.
Conclusion: The TSC Barzini produces an inherently different lather than does my Stirling 26mm Finest Badger when using the same soap with a similar soap/water ratio. And how is that for over thinking (and over-writing about) something that is so simple?
The razor for this AM was the Jade 7/8" BRW, and the result was just as good as yesterday! BBS+
