Observations
Expt Table remarks: Found 0.1% crystal upon filter (Step 1); Initially after 10 min feed found turbidity in white mass (Step 3); After over night mass became clear (Step 3). Stray measurement outside the fixed columns (Iodine value / Time block, positionally under Step 2 'Other'): 68.5 at 2, 41 at 4, 27.5 at 5.5 — parameter unconfirmed (IV assumed from header); not dropped.
