Catching Clouds – Making Kozo Tissue

| wonko

Last PAQ meeting I had the privilege of running the group’s Hollander Beater, processing my most recently cooked and cleaned paper mulberry pulp. In the past I have hand-beaten it, but was determined to give the mechanised processing a try (to see if I could).

The pulp floofed up into delicious clouds of softly frayed pulp after a few hours circulating in the beater. I took the beaten pulp home, rinsed it a couple of times and then pressed it into pulp storage sheets. I ladled 3 x 2L scoops of pulp into my old A3 mould and deckle, smoothing it off with my hands, then added them to my press, couching between. The batch made 6 such sheets.

After pressing, these pulp sheets were set to dry over the next week – when dry they are storage stash stable.

For the tissue session, I re-hydrated one of these sheets in a tall bucket, tearing it up until it was finely shredded. I then agitated it with my electric drill and a paint-stirrer attachment until it was separate and fluffy again. I brought the bucket of pulp and most of my sheet forming equipment to the PAQ meeting last Sunday and set up a bit of a production line.

I have a large vat (so I can easily move my A3 frame in it), and half-filled it with water. Then added 2 scoops of pulp to the water in the vat, along with half a bottle (about 100ml) of pre-prepared Methyl Cellulose (MC) gel and about 200ml of strained Okra mucilage. The MC was to act as an internal size for the paper (to help with the strength and crispness). The Okra mucilage acted as a suspension aid to keep the pulp from quickly sinking to the bottom of the vat.

After a thorough mix to fluff up and evenly distribute the relatively sparce pulp in the water, I was able to pull sheets by catching the “clouds” that so delicately hung in the water.

White Mulberry Sheet Formation TLDR

| wonko

…so, having liberated 110g (dry weight) of bast fiber from a lovely bunch of Andy’s mulberry tree prunings, it was time to do something with it. I decided to use half (55g), and added it to a plastic container and added a little water to re-hydrate it.

Using the patented “AndyMalletâ„¢”, and a recently purchased Ikea bamboo chopping board wrapped in an old pillowcase, I began whacking the re-hydrated pulp using the hardwood edge of the mallet. The shaping of the mallet is perfect, so much mechanical advantage that the fiber was squished in no time.

After about 15 mins of beating, I did a “suspension test”, decided another 5mins was needed and whacked on for another 5ish minutes. BEATING fiber frays the cellulose tubes, allowing complex interlinking of adjacent fibers.

With a tub of “fluffy” beaten fiber, kept in suspension with Okra slime, it was time to try forming some sheets.

My setup was very basic, and after experimenting with the only “vat” like container I had, I abandoned the conventional “pulling” of sheets in favour of the “pour over” method as a means of testing the pulp properties.

Hand Made

One of many goals, long term, is for me to make and fold my own paper. By “make paper” I mean collect, process and form sheets from pulp. I clarify because one school of thought around “making paper” is laminating or treating existing sheets – I do that also, but yeah, there is a distinction.

I attended a workshop out back of Gympie with Dion Chandler, using my newly acquired mold and deckle, and pulled (get the lingo 😛 ) A3 sheets – by the end I got pretty consistent at it but need more practice.

I ended up making A3, A4 and a smaller “letter” size”, love the deckle edges and the structure of the sheets. I have also Methyl Cellulosed some and, so long as I apply the MC to the paper (and not the glass I am sticking it to) then the sheets come away crisp and sturdily hold folds crisply as well.

That workshop we were pulling from a vat that started mostly with cotton pulp, and gradually had recycled kozo (mulberry) to it – quite a resilient mix. the resultant sheets are precious and wonderful.

Workshop with Dion Channer

A Day With Dion Channer

On Sunday during the weekend the PAQ “All Stitched Up” exhibition opened in Gympie Regional Gallery a fortunate group of paper makers were able to spend the day at Dion Channer’s paper mill. Michelle, Vanessa, Wendy, Sue, Heather, Ann, Joolie, Marjorie and me, Peter were in for a treat with Dion and his partner Sue Purnell. Surrounded by the bush, among music rooms and yurts, pavilions and lakes, Dion’s mill was a large shed with a bespoke collection of gear and infused with the passion of a master papermaker.

Over a morning cup of tea, PAQ members talked with Dion about individual goals and hopes for process assistance, we learned about the available fibres and equipment we would learn to use during the day. Following a tour of his eclectic property, we retired to the mill and began with an orientation.
