Recently found a couple of boxes of vintage
Faber Castell 9030 drawing leads with a gross each of
F &
B drawing leads. Each tube holds 12 leads while the version currently in the market just holds 10 leads each. Made in Germany. Additional photos in
Flickr photostream:
photo 1 through
photo 5.
The
B leads had developed a heavy build up of white residue. Possibly the waxy lubricating component on the outer layer of the graphite core oxidized during extended storage just like some colored pencils are prone to developing a
"wax bloom".
Love the
F grade leads for general sketching. They keep their sharp points longer while still gliding smoothly and producing nice dark marks on the paper. Unlike the softer graphite grades, they do not seem to develop the white residue build up as quickly during prolonged storage.
Highly recommended.
