Dimy grass

Added some H2O o (A22) and heated slightly until nearly complete dissolution.  Seems only slightly undersaturated at 38 C.  

Cooling in jacketed beaker (ambient 31.3 C): Still unsaturated at 34 C.  Crystals formed at ~32.5 C.  At 32.0 C, mass of very fine needles suspended in clear liq.

Dissolving another batch.

Plan: use (A6) (now ~350 mL) to dissolve another 250 g of fertilizer at 60 C.

The scale reset itself halfway so the total wt is not known.  The remainder of the bag is 833 g but certainly more than 168 g were added. 

Heated (A6) with new load to 60 C.  Last grains dissolved at ~58 C.  Tan liquid, OD ~5mm with carbon rod. 

Filtering through snob at 52-55 C into jacketed beaker. Re-boiled the ppt with some filtrate to ~80 C and added back to filter.

* Liquid (A23) clear golden yellow, saturated at 51-53 C.

* Solid (A24). 

Re-heated liquid (A23) to 54 C, let cool in jacketed beaker from 53 C.  At 50 C put some seed crystals in it.
