Bone Dying Instructions and Results

Posted on by

I asked my wife to help sift through all the research I did online and she came up with the following experiment to see which processes worked best for turning bone as black as possible without loosing too much of the surface texture. The results so far suggest that the rougher the bone’s surface the more the dye will infiltrate but it didn’t soak into the bone very deep on any of the pieces.

Bone Dying Test: Instructions

 Degreasing (after this step, wear gloves)

  1. oven cleaner method: follow instructions on product
  2. dish soap: wash like a dish, rinse
  3. nothing: easy

Surface Treatment

  1. sand to 1500 grit
  2. sand to 1500 grit, then soak in vinegar 30 minutes and rinse in water with baking soda
  3. sand to coarse grit

Dyeing (use 2 small pots for different time lengths)

  1. put pieces into pot
  2. cover with just enough (normal temperature) water
  3. add a few drops dishwashing liquid
  4. bring to simmer (NOT BOILING)
  5. add ¼ bottle of dye (+ salt if dye container says so)
  6. keep at simmer (NOT BOILING) for either 15 minutes or 1 hour
  7. remove from heat and allow to cool (keep bone in pot)
  8. once water has cooled to room temperature, remove and rinse pieces

Finishing

try nothing, mineral oil, or carnuba wax

15 minutes in dye
no degreasing dish soap oven cleaner
fine sand  1 – light grey  2 – light grey  3 – light grey
coarse sand  1 – grey  2 – grey  3 – grey
vinegar  4 – near black  5 – Black  6 – Black

 

60 minutes in dye
no degreasing dish soap oven cleaner
fine sand  7 – grey  8 – grey  9 – dark grey
coarse sand  7 – black  8 – near black  9 – black
vinegar  10 – Black  11 – Black  12 – Black

Panther Toe nails – Staining bone black experiment 1: Black Dye Process

The following pictures demonstrate how we prepared and dyed the bone in the first attempt to get black bone without loosing too much of the quality of the bone. (Complete steps in next post)

(Above) First off, I made 12 ‘Panther toe-nails’ from two slightly different pieces of bone. I sanded the front of all up to Fine 1500 grit and left the other sides at Coarse 100 grit. I didn’t spend that much time on sanding, I just wanted to get an idea of the impact on the various surfaces.

(Above) Next, we labeled each of the pieces one through twelve.

(Above) Some of the pieces were degreased in oven cleaner while others were scrubbed with dish-soap to see if we could get the oils out of the bone. Also some pieces were left alone.

(Above) In this step, we just soaked some of the pieces in vinegar to slightly roughen the surface.

(Above) We also thoroughly rinsed the vinegar off the pieces that were soaked.

(Above) Then we neutralized the vinegar with a solution of baking soda and rinsed again.

(Above) Next, we tied the pieces to chopsticks and put them in pots.

(Above) We filled the pots with just enough water to cover the ‘toe-nails’ (2 cups) and added a little bit of dish soap to each along with 4 tablespoons of the black dye and a 1/4 cup of salt.

(Above) We put the pieces back in and tended them while they simmered to make sure they didn’t boil. One pot was on for just 15 minutes while the other continued for one hour (turned into the mess pictured above).

(Above) We left the pieces in the water until they cooled down to room temperature then rinsed them under cold water thoroughly.
