Notes from Relevant Word Doc (created & for me mostly)
Mass %= (mass of solute/ total mass of solution) x 100
PVA label recommends 7.5% solution:
0.5 pounds (226.796 g) per 1 gallon of acetone (2994 g)
Volume to weight conversion: http://www.aqua-calc.com/calculate/volume-to-weight
1.25 cups Acetone (72.6 grams)
Need 23 g Acetone for 7.5% solution
Fossils already consolidated:
1.Pictures- Paleontology- Cenozoic – 2014- 2014 compilation- 053 to 063
2.Pictures- Paleontology- Paleozoic- 2015- 05-23-> 019 & 020
Careful with Acetone (very flammable) & PVA, dispose of at _____ (look up pickup weekend schedule)
1. Wear work clothes, rubber gloves & usf goggles
2. Get scale, acetone, container, lid, fossils, cardboard, plastic spoon, wide tweezers, napkin & PVA-15
3. Go outside
4. Place container on scale & zero. Carefully add Acetone until it is ~280.7 grams. Place aside carefully
5. Recalculate mass needed for 7.5% solution if necessary (x/mSolution times 100= 0.075)
6. Measure out necessary mass of PVA-15 from spoon to napkin on scale, then carefully into acetone
7. With tweezers grab small bone and submerge for 30 seconds (until all or most bubbles come out)
8. Place on nearby cardboard and allow to dry in sun
9. Repeat step 7 & 8 if necessary
10. Lid solution
11. Take to.... on 579 during pickup day
Consolidation III List (Ineo, still need to consolidate these as of 1/26/18 )
1. Joshua creek Gator Vert
2. Late 2016 Joshua creek fish spine
3. Dugong rib w/ predatory marks
4. Puffer/porcupinefish mouth plate (one treated w/ acid)
5. Sand tigers? (roots, at least Apollo beach specimen)
6. Unknown weasel (or school shark) partial tooth (likely use small tweezers; no idea which specific one I was referring to)
7. Brush partial mammoth tooth? (Like I did for horseshoe crab molts, DO NOT brush part I superglued back on, makes nasty residue when those 2 mix (tried on a piece of fossil turtle shell)
8. Partial unknown vert (one I tried to get ID'd @ 2017 Fossil Fest)
Probly more I need to/ should consolidate
