Well.... I need to get a 32% aqueous solution of calcium chloride CaCL2. Yes, you can mix it by weight and volume, but because sometimes the CACL2 can be finicky to get right..... I'm not a chemist. I've never wanted to use molar equivalent measurements. I've never have good luck by just guessing or about the right cup and teaspoon thing. I've never mixed it. I use the solution for beer and cheese making. It gets kinda expensive buying it premixed. I'll use this hydrometer for other things too. So that's about all. tp
So... Part 2. 100g of water and 41g of my calcium chloride (CaCL2) came out to be 1.320 specific gravity Sg. The Specific gravity of an aqueous solution of 1.322 is a 32% mixture, at 75°F. I was shooting for 32% to 33% mixture. My Specific gravity is 1.320, I'm good with that. All the mixtures I've seen using grams, milliliter, cups, teaspoons and the like were off by a bunch. Even though the CACL2 I am using is food grade, supposed to be pure, none of the so called formulas I found on line gave me this ratio. The scientific papers I found always referenced Specific gravity vs percentage of solution in distilled water. So that's what I did. Now I can use this for dosing my concoctions with some confidence of proper measurements. tp
This was very inexpensive, so my curiosity took over. The OG Old Spice. Originally marketed to women. Review to follow.
they appear to be glass..hope so..approx 1994 -2000 date. from wiki.. ...Combe Incorporated began shipping Aqua Velva exclusively in plastic "Shatterproof" bottles on February 1, 2010. Previously, it had been packaged in glass bottles.The change was made reportedly at customer request, and the new plastic packaging contains the same product, with no changes in formulation.[7]
A stainless Rolls Razor in mediocre condition and I suspect it's missing the hone, but the box and case are in decent condition, and I suspect the spare blade is in near new condition. $13 + shipping A NOS (or near enough) tin of strop dressing for a little over $10 shipped. First shaving related purchases I've done in a while. Both are backups for existing items in my collection. The Stainless Rolls Imperial No. 3 are quite rare, even if it doesn't seem like it, since one or two are always on eBay, along with hundreds, if not thousands, of nickel plated brass Imperial No. 2's and aluminum Viscount models, along with a smattering of gold or silver plated models. It's a pity I never got on with the Rolls in my early wet shaving days. I would have gotten a nice head start on building a collection.
Ditto. A vintage NOS Spear & Jackson machete for clearing blackberry bushes. I believe this is the style called a 'tapanga,' common in parts of Africa. Not my first choice, but a solid second.
