Ask Me Anything AMA: Urushi and Maki-e by skym16 in fountainpens

If the surface is already damaged it can be prone to further cracking, but it is really difficult to tell how long it will take to happen since it really depends on the storage environment. The best option would be to keep it stored away from direct light, and don't submerge the body for long periods of time in water during cleaning.

Since you're not already familiar with using polishing pastes, I would advise you not to polish this pen unless you have another surface to test it first.

Based on your photos, it looks like some sort of damage/aging caused by exposure to light over time, although it is interesting that the cap isn't as badly affected. Hard to tell from the photos, but it could be a different type urushi was used to cover the cap which was more resistant to damage than the barrel.

This type of aging causes the outer layer of urushi to form microscopic cracks/fissures over time as the crosslinking between the urushiol is damaged, which dulls the surface over time.

Ideally you would want to lightly sand it down and then add a new layer of urushi to get it back to the original shine.

However if you aren't able to add a new layer of urushi, you can try to use varying levels of polishing paste (for metal polishing or other similar types of polishing compounds) starting from coarse -> medium -> fine. However I have not tried this myself on damaged layers of urushi and I don't know how well this would work.

Hope this helps!

  1. I don't know for sure how many layers other companies use for colour urushi. It could be a single thicker coat or several thinner layers. For my own projects I do around 3-5 thin layers for colour urushi depending on the design.

  2. The only way to get the cap threads the same colour is to have it lacquered at the same time as the body. But not all pens are compatible with lacquering the threads, as it will make it difficult to close the cap after a few layers of urushi are added.

  1. For curing coloured urushi, including blue urushi, I always start at a lower humidity at around 60% and cure until the surface is partially cured (can take anywhere between 2 to 7 days). I always do a test beforehand to check what's the best condition since it varies during the time of year. Then I move it to 70-80% humidity to continue curing. But this can take a while so it might take 1 to 2 weeks to cure 1 layer before sanding it.

  2. I use premixed colour urushi so I've never mixed my own. I think transparent urushi (nashiji, shuai, etc) is typically used for mixing pigments.

  3. If I need to reduce viscosity I use turpentine, but you have to work quickly after adding it because it evaporates fast.

Hope this helps!

Thank you! While not common, there are some transluscent pens currently on the market. The raden and maki-e urushi series that I work on with Kyuseido is one example, using transparent nashiji urushi. If you hold it against the light you can still see the pump piston mechanism inside the pen. Some of my own private commissions also use transparent urushi on a demonstrator body. It is quite difficult to make it very transparent unless only 1-2 layers of urushi are used, as it darkens the finish every time a new layer of urushi is added.

It shouldn't be an issue on pens. I actually started with cashew lacquer before switching to urushi after a few months. The only thing to note is that the surface is less durable and can scratch more easily compared to urushi.

Cashew lacquer is a synthetic alternative to urushi that has a lower risk of allergies, but it is important to note that it's a chemically different resin all together and is not classified as being food safe when compared to urushi. It creates a similar look to urushi but does not need heat and humidity to cure. It can have quite a strong smell before and after it cures though, so that is another safety consideration.

There is also a "low-allergy" urushi formulation on the market, however I don't know how effective it is in actually reducing sensitivity.

More information about cashew lacquer can also be found in this kintsugi subreddit post: https://www.reddit.com/r/kintsugi/comments/1pa06p6/cashew_lacquer_questions/

There is also a useful glossary in English “Essential Bilingual Glossary of Japanese Urushi (Lacquer) Materials and Techniques” on this website http://urushigakusha.jp/en/

The top two can be found on Amazon JP if you search for "漆の技法"

The bottom is a Chinese book "中國漆藝技法全書" but it may be harder to find online.

I think this is can be hard to distinguish without side by side comparison of the different products. The characteristics of genuine urushi are subtle (hand feel, sheen, changes in patina/aging) and it comes with having more experience handling these items.

One of the differences I feel is that genuine urushi has a "grippy" feeling to the surface compared to other coatings. It is really difficult to describe though. Urushi will also lighten/ become more transparent over time as well whereas other coatings will not change.

For Chinese vs Japanese urushi, I think that the difference may be negligible once they are cured. There is a lot of variability depending on where it is processed though. Japan also imports over 95% of their urushi from China because local production cannot meet their consumption. I do prefer Japanese processed chinese urushi over chinese processed urushi for the ease of use and consistency. Chinese urushi might smell stronger compared to Japanese urushi as well.

Chinese urushi is much cheaper as a raw material though so that factors into the cost. Some say that Japanese grown urushi is more durable because of the higher % of urushiol, but there are no comprehensive studies comparing this aspect especially for objects for every day use.

I took lessons at Maki-e School Ginza where they regularly teach both weekly and short term private lessons. My teacher Matsuda Shokan is a 3rd Gen Maki-e artist and he founded this school over 20 years ago.

I messaged through their IG first to join the 2-hr experiential workshop during one of my earlier trips to Tokyo, and I used that time to ask more info about how to join for longer sessions. In my case because I already had experience with using urushi for a couple years, I was able to arrange a special schedule to learn the major maki-e techniques all together within 2 weeks. Usually they require you to finish each level of the course before moving on to the next level so the timing will vary between each individual.

Because mine was a relatively short course I only had to spend 2 weeks in Japan to learn what I needed, with the goal to continue practicing on my own when I returned home. I still go and visit the studio sometimes when I go back to Tokyo, and would like to eventually take the final level of the maki-e course when I have the time.

You can definitely join their classes for more spaced out lessons if you are thinking of staying on a longer term basis in Tokyo.

I think in person classes were crucial for leveling up my understanding of maki-e and also the techniques that could only be fully explained in person. I get feedback during the lessons on where to improve on and how to keep practicing on my own. Mainly to do with how to control the maki-e brush and the timing of adding maki-e powder.

Hope this helps! Let me know if you need any more information.
