SUMMARY

The discussion centers on the lack of standardized parameters for quantifying the mixing quality of powders, specifically using flour and brown sugar as examples. Participants highlight the challenge of measuring the degree of mixing, which ranges from visibly distinct layers to a uniform color. Various methods for assessing mixing quality are suggested, but no consensus on a specific measurement technique exists. The conversation emphasizes the need for a reliable metric to evaluate powder mixtures in both culinary and industrial applications.

Let's say you have two powders (say, flour and brown sugar) which are to a certain degree mixed with each other. Is there a commonly accepted parameter that determines how well mixed this mixture is? Obviously there's a difference between having the mixture so unmixed that you can see a line dividing one powder from the other, and having the mixed so well mixed it's a shade of light brown rather than brown and white, but I don't know how I'd determine that quantitatively.

To my knowledge, there is no standardized way of measuring how well mixed two powders are.

However, there are many ways of measuring it this, how do you think it could be measured?
