Three layer mask (inside layer --> outside layer)

<img src="./KC47117_layers.jpg" height="600">

- the outer layers look like some sort of pressed pulp, not as fibrous and stringy as the N95 masks
- the middle layer looks more like the N95 mask outer layer, except with smaller fiber width

### SEM 

When imaging in the SEM without sputter coating the material you disappear if focus too closely (either blowing away or disintegrating from the electron beam - hopefully this isn't damaging the SEM??) the same way that the dust particles on the Gerson N95 did. 

So all images have a 20 nm gold layer on top 

#### inside layer

#### middle layer 
this looks to be the layer doing the most filtration

#### outside layer
same as inside layer

progressively zooming in on the same spot:

### Optical 
checking for burn marks or any deformation on the sample that was put in the SEM without sputter coating .. couldn't find anything
