How many scoops in 1 f/s Foundation bag?

[extemter]

Is there a smaller scoop on the market than the 1/32 tsp scoop sold by SN? I'm still figuring out my foundation ratio and I want to be able to make single-use batches. I have a precision scale so I was thinking of weighing out my foundation mixes but I don't know how dense the different bases are. (In baking, for example, weighing ingredients is more accurate than measuring them by volume.)

I started out with 4 Heavy Ivory:1 Warm Gold and I kept adding a scoop of Heavy Ivory and swatching each time until I reached 8 Heavy Ivory:1 Warm Gold and finally realized that Warm Gold isn't yellow enough for me. Not wanting to end up with another large batch, I mixed 4 Heavy Ivory:0.5 Buttery Gold (approximating the half scoop) and while this mix looks better, it's still not perfect. I did a full face application with 4 Heavy Ivory:0.5 Buttery Gold and I still have enough for 2-4 applications (difficult to judge) of a mix that I don't want. I know that I can reuse my existing mixes in new mixes, but I'd rather not need to keep meticulous records. Maybe I'm just too fussy about this process!

Obtaining a smaller scoop is not easy. They exist. I have a stainless steel 1/64th that I bought as a 5 spoon set (around $6-7 plus shipping), and a .05 ml plastic one (about 1/3 of a 1/32) that I got in a kit from TKB Trading ($20 minimum order, plus shipping...converting this one to tsp has me baffled for the moment...to get a usable recipe will take some work unless you just use that scoop). I also have something used in dying fabric (Grey dye spoons), but again, they are quite expensive (over $50 a set plus shipping, but there is a spoon in the set that measures 1/64 and 1/128). Honestly, it would be easier and more cost effective to buy more Ivory base.

As for a way to use your precision scale, why not weigh a scoop of each base. If your scale is sensitive enough to weigh them, you could work from there. (Yes, the analytical chemist in me is coming out, at one time I worked as a lab analyst at a pharmaceutical manufacturer....IMO it will take a very sensitive scale to do what you want.)
