cobalt pigment

Chopped up filter paper with (ME101) (small amt of greenush-brownish black ppt).  Put into beaker with H2O to wash off remaining NaHCO3/Na2CO3.  Then decanted the liq (clear white) and merged into (MEF5).

Pipeted out ethanolic phase of (MEF2) (clear light yellow) as (MEF2p), merged it into (ME1p).  Siphoned out the blue liquor phase of (MEF2) (blue sly cloudy) as (MEF2q).

Siphoned out supernat of (MD66) (sly peachy, sly cloudy) as (MD66n) (pH ~7).  No reaction with K4Fe(CN)6.
