Yes, activated charcoal can be coarse with fairly large particle and it can be fine, and even 'powdered', however by definition, Activated Charcoal "is a form of carbon processed to achieve a microporous surface area available for adsorption or chemical reactions". So even the powdered AC still has a relatively large surface area for it's size; the 'powder' granules aren't really smooth if one looks at is closely (say, with a microscope.)
Hi all, I want to make a layered soap maybe with activated charcoal. I'd like each layer to look a little bit textured and rustic... specks on each layer of soap to give it a little more interest. I am wondering if I can achieve this with a little bit of activated charcoal mixed in at trace (not completely mixed in to the soap)? I am afraid that it is going to darken each layer instead of having the effect I want. If anyone has tried this or has any other suggestions for achieving what I am trying to do, I'd appreciate it!
I have only ever used AC well mixed into soap as a colorant, so I have no idea how it would look if one attempts to create a speckled soap, but it is worth a try to see how it looks. For experimental purposes, I'd do a small batch to see how it turns out.
If you meant 'in each layer' as in suspended within the batter in the layer, then make sure the batter is already at a trace that will hold it in suspension when you add it. I'd say, don't mix it in until right before you pour the layer, adding it with each layer just before pouring that layer. That way
maybe it will stay in suspension as speckles. Maybe it won't; I really don't know.
You could really do the same thing with table salt, mixed at a thick trace, just before pouring.
Don't use a roughly ground salt, though as it can be too scratchy; some have reported actual abrasions occurring with Pink Himalayan salt in soap, so I suggest you avoid that & NEVER grind your own, as it only make it sharper. I would avoid Volcanic salt as well, for the same reason, as the Volcanic salt I have is very coarse & looks sharp.
