Second Furlough Day

Not much to say about today that isn’t already in the Lab Notes. I didn’t quite make my eight hour committment. Oh well, “stuff” happens. In addition it was very overcast today, so I’m not sure how well a Becquerel daguerreotype would have developed. Nevertheless progess was made – and never mind perfection.

Lab Notes 8/17/09

Sample Lab Notes

1) Set up for plate polishing.
2) Cut out and zig-zag hem 15 microfiber rounds to use for polishing, Cut size allows five rounds per polishing cloth.
3) Polish off plate that was used for fuming test last time.

Steps:
0.5 Mic alumina slurry 2 minutes – bare foam pad
0.03 Mic alumina slurry 2 minutes – bare foam pad
Nushine II S  2 minutes – foam pad with microfiber cover
Rouge 2 minutes – foam pad with microfiber cover
Lampblack 2 minutes – foam pad with microfiber cover

I noticed that the bare foam is starting to deteriorate and even though I vacuumed it off, it created a few “squiggles” on the plate (random single scratches as if from a piece of dirt). I think I will switch to using a fresh microfiber at each step. I will have to see if machine washing the microfiber rounds is successful. If not, I am going to start testing various disposables. I also had some problems with the dispensing tip of my slurry bottles being clogged with dried out polishing compound. I guess I am going to have to polish plates every day… :)
