Recreating a Central Asian Cloth Pattern Utilizing an Extracted Motif, a Handmade Knife, Scratch-Made Ink and a Hand Carved Wood Block

~ Baron Jali Bukha, mka Grav Weldon



Through the construction of a period-style woodcutting knife, a wood block carved with this knife, and inks created from period ink recipes, I have attempted to recreate a period-style block print, utilizing materials replicating a 14th century patterned silk brocade cloth.

A Brief History of Block Printing on Fabric

It is difficult to pin down exactly when humanity first started printing fabric, but the earliest surviving examples of block printed fabric can be found in China from the Han Dynasty (206 BC–220 AD)1, 2.  While the earliest examples of block printing on fabric can be found in China, other forms of textile decoration came to prominence there over time. Printing on paper eventually became the primary application of the block printing process in China 3.

Block printing technology would develop through time in several cultures.  There is evidence of block printed fabrics in Coptic Egypt as early as the fifth century, as can be found in funerary garments that bear block printed motifs 4.

Examples of Rus block printing 5 on fabric has been found in 9th and 10th century graves in Kiev  6  and Chernogov 7. They also appear in tapestries and on clothing in Iran and Iraq during the Seljuk period 8, spanning the 11th and 12th centuries.

By the 12th century, block printing fabric had become fairly sophisticated in both Egypt and India 9 and would flourish in both regions for centuries.

The technology of block printing textiles in India from the 12th century onward was particularly advanced, allowing for highly detailed and brilliantly colored designs on fabric.

In western Europe, block printing on fabric arrived around the latter half of the 13th century and only really flourished in the Rhenish Provinces of what is now Germany.

and Albert Museum, London.

The advanced techniques developed in India would eventually make their way to Europe and transform the way garments were printed in Europe, but not until the mid-17th century 10.



The cloth I attempted to recreate comes from the 13th or 14th century, a central Asian piece from the Mongol period currently in the holdings of the Cleveland Museum of Art 11 , seen above.

To replicate the design and pattern, I took the following steps:

I made this knife so I would have a period-style tool I could utilize to carve wood into blocks by hand for use in block printing.

For this project, I used:
  • A section of steel bar stock
  • Coal for use in a forge
  • A forge
  • Epoxy
  • Wood glue 
  • Cherry fruitwood
  • Clamps
  • A grinder
  • A sharpening wheel
  • A burring wheel
  • Sandpaper
  • An acetalyne torch

The first step in this project was to make a knife similar to what would have been used to carve a wood block during the Middle Ages.  I searched for and found several images of examples of wood carving knives 12

The extant knife I chose to duplicate is from an archaeological dig in Novgorod 13 . The city was at one time part of the Mongol Empire and the knife could have plausibly been used to carve the block I attempted to
recreate.







I picked this particular knife because the image, shown here on the left, came with scale measurements.  With this information I was able to make a scale drawing of the original blade.



At this point I needed assistance. I engaged the help of a friend who does a lot of metalwork. He cut the basic shape I had devised from a steel bar using an acetylene torch.



I was then left with this knife-shaped hunk of steel.




I then took that basic knife form to a friend's home to utilize his coal forge to normalized the steel. 

Normalizing the blade is accomplished by heating the steel to the point it ceases to be affected by a magnet.

Once the metal reaches that temperature, it is then allowed to cool slowly.  Doing this helps soften the blade to make it easier to shape.


Once the metal was normalized, I ground the blade into shape using both a grinder and a belt sander.

I then took the blade back to the forge and heated it to demagnetize it again.  This time, we quenched the blade in oil to harden the steel.


When the blade had cooled, I placed it in an oven at a controlled heat of 350 degrees for four hours to temper the metal.  I then cleaned the blade and put an edge on it using a belt sander, a grinder, and a sharpening wheel.

Once the knife had a functional edge, I took it to another friend, who helped me acquire a very sharp edge and a higher polish on the blade using a deburring wheel.

With the blade complete, all that remained was adding a hilt.


I took two pieces of cherry and carved out the area where the tang would reside, using knives and a Dremel tool.


In period, pine rosin would have been used to seal the hilt to the tang. Since I had no pine rosin, I used epoxy to fill the tang cavity, and sealed the rest of the hilt with wood glue, clamping the hilt in several places to fuse it to the blade tang.


Once both the epoxy and wood glue had cured, I worked the hilt with a belt sander and softened the shape using several grits of sheet sand paper.

I made the hilt somewhat shorter than the original so that it could tuck conveniently and comfortably into the palm of my hand.  This adjustment gave me a greater degree of control over the knife.



Extracting the ogive motif from the extant 14th century Central Asian fabric

I selected this particular fabric to replicate because this particular ogive motif is contemporary to my persona’s time period and location. My persona would have lived in and around China and Central Asia during the latter 13th and early 14th century.

The design was found in a period silk brocade fragment that is currently housed at the Cleveland Museum of Art. I obtained photographs of the piece from the museum’s website.


Utilizing skills I have developed with modern technology, I extracted the basis motif of this palmette ogive from a photograph of the tapestry with the assistance of Adobe Photoshop. I then rendered the motif into a computer file that could be printed.



Carving the Wood Block

Once I had built a knife similar to what would have been used for carving wood, and selected and extracted a motif I wished to replicate on fabric, it was time to carve a block. For this part of the project, I used:

  • A piece of cherry fruitwood
  • The knife I made myself constructed from cherry fruitwood, epoxy, wood glue and steel
  • An Exacto-style razor knife

My preferred wood is cherry.  Cennini 14 in particular recommends pearwood, preferred in period not only for its hardness, but also for its tightness of grain.

The chosen board was both planed and sanded perfectly flat.  Flatness is necessary for a proper print.  I lightly braised the surface of the block using a laser engraver to mark where I would need to carve.

The block was carved using a modified chip carving method.  I figured out what worked best for whittling this type of relief carving by making several preliminary linoleum and cherry blocks.  While I wish I could say I only used my period wood carving knife to whittle out the palmette ogive for this project, many places were just too fine for the thickness of the blade.  I used the period knife in conjunction with an Exacto knife with plenty of replacement blades.


The shape of the tip on the period knife was especially useful for popping out chips and cleaning and smoothing carved areas.  I ended up using the period knife for around 30% of the carve.  I suspect that percentage will go up once I have had more time to get to know the knife better.



Making a Simple Period Ink for Block Printing

My first experiments with trying to produce period type ink was a mixture of rust, a pinch of gum arabic, and boiled linseed oil, an attempt to augment Cennini’s original recipe 15 inspired by the experiments of Viscountess Morrigan Clubfoot of the Kingdom of Avacal.

I determined my ratios off that first batch and ended up with a very oily, messy paint.

I did get a few decent printings and I learned a few things from the experimentation.  Not only did I determine that the best way to apply oil-based ink to the block was to apply ink to the brayer via the stamp pad, but I also learned that wood works better than linoleum for even paint transfer with oil based paints.

The cure time for this type of paint is five to seven days of air drying.

At the same time I made and experimented with rust ink, I tried a similar formulation using powdered indigo.  That ink did not take at all.  The rust certainly dyed the fabric well, but eventually the chemistry of the iron salts will tear up the fibers that contain them.



For the purposes of this project, I decided to use one of Cennini’s recipes to make the block printing ink used for this project’s sampler.  The recipe is quite simple.  It calls for charcoal made from pine ground to a powder and mixed with a liquid lacquer.  Cennini does not say what kind of lacquer to use, so I had to experiment a bit.

I utilized these ingredients:

  • A molcajete and a round jar for crushing charcoal
  • Charcoal
  • Boiled linseed oil
  • Gum arabic


I ground compressed charcoal with an improvised mortar and pestle.  I added a pinch of gum arabic and then started adding boiled linseed oil, mixing the ingredients until the ink was about the consistency of maple syrup.


I then put thick cotton gauze on top of the ink to make a stamp pad.  I rolled my brayer across the ink pad and then applied the ink to the block.  The ink has a thinner appearance on the block than modern inks and paints.  However, because the ratio of dry to wet was correct this time, there was no excess oil on the fabric from the printing.  The period ink printed consistently for the creation of the sampler.



Block Printing on Fabric

Block printing on fabric is a relatively simple process.  There are two documented ways which textiles were block printed prior to the 17th century.  The first was described by Cennini in Il Libro dell’Arte., which I referenced earlier.  A frame is placed on top of the fabric held up between two tables.  The inked block is then place within the frame and the fabric underneath is rubbed with a smooth stick or rod.


The second period method was originally described in Nüremberger Kunstbuch 16 during the late 15th century.  The fabric is placed on a table with a frame placed on top.  The block is inked and placed on top of the fabric within the frame.  A rolling pin is then rolled across the top of the block to evenly apply pressure to the fabric.



There are easier ways than these to block print.  At its core, block printing is applying paint to a decorative block and pressing that block into fabric to leave an imprint.  There are many ways to accomplish this.

Most modern printers use a brayer for applying ink rather than using the inking glove which was commonly used in period.  A brayer is a modern tool which is essentially a paint roller coated with either hard rubber or foam.  This roller allows for a very even coating of ink or paint.

There are several ways to apply paint to the block.  A brayer can be used to apply the paint directly to the block.  The brayer can also be user to apply an even coat onto an inking plate which the block is then pressed into. Some forgo using a brayer all together and apply the paint to the block using a homemade stamp pad.  All these methods are valid.  Personally, I prefer applying paint to the block directly using a brayer.

To create a design using blocks, one must plan out the layout for the overall design.  I recommend cutting all the panels for the proposed garment and block printing those individual panels rather than block printing whole lengths of fabric.  This not only lessens the amount of block printing work required, but also allows the artist to plan how the printed designs meet on the seam lines. Using a yard stick and occasionally a compass and protractor, draw out a grid on the fabric using fabric chalk at the printing locations.


Once your fabric has been planned, it is time to start block printing.  I generally place between four and eight layers of felt between the fabric and the table.  This helps get a sharper printing and lessens wear and tear on the block.

There are several ways one can press the inked block.  Using a rolling pin is quite period, as the Nüremberger Kunstbuch describes. Some use a rubber mallet. I just use my body weight to press in the block, pressing multiple places on the block.  The larger the block, the more places on the block that must be pressed to get a clean printing.  Once the fabric is block printed, the paint has to be cured to make it washing machine safe.  With many modern inks and paints, heat is required to cure the fabric print.  Some, especially period inks, require other steps to be made washing machine safe.

For this project, I used:
  • The piece of cherry fruitwood I had carved into an ogive motif with the knife I made myself constructed from cherry fruitwood, epoxy, wood glue and steel
  • Ink I made myself from a recipe by Cennini
  • A brayer
  • A piece of silk for printing
  • Several layers of felt
I placed between four and eight layers of felt between the fabric and the table.  This helps get a sharper printing and lessens wear and tear on the block.  I use my body weight to press in the block, pressing multiple places on the block.  The larger the block, the more places on the block that must be pressed to get a clean printing.


Conclusion

The purpose of this project was to artistically explore the origins of my block printing craft. Learning how to carve blocks was difficult, especially with my fine motor control issues that come with my dyspraxia, but it was a worthwhile endeavor.

What I found more interesting was how well the wood carving knife actually worked for carving the block. I had a few knife makers scratch their head over the shape of the blade, but its curve makes a huge difference in how I control it. With the augmented handle, it acts like an extension of my hand.  It felt good carving a design with a tool I made myself.

The block printing itself was straight forward. Aside from making the ink myself and the differences in the curing, the printing was just like any of a dozen or more I have done in the last year.

There is a Zen to the process that makes it feel common and simple, yet the rendered results are elegant and often intricate.  That is the beauty of this fiber medium.  It allows almost anyone to create a higher level of garment without spending a fortune in materials or time.
