Q. What do egg shells and paper have in common? A. They are both made of calcium carbonate. At least the “stone” paper from this Kickstarter project is made from the same stuff as egg shells. Nick, the creator of the Da Vinci Notebook, sent me a sample of this interesting paper and I decided to put it through a few paces.
The first thing you’ll notice about the stone paper is that it feels very soft and that there is almost no discernible texture to the paper. The phrase “smooth as a baby’s bottom” comes to mind. It also has some heft to it. I cannot find the paper weight in the information that Nick sent me but I’d guess that a single sheet of stone paper weighs about the same as at least 3 sheets of Rhodia. Seems to me that a 100 page, 5″ x 8″ notebook of this stuff would weigh a pound or more. Lastly, in the initial impression category, would be the color. The paper has a flat white color to it. It is not bright white like most copy paper but it is not in the cream color range either. I’d call it flat or off-white or soft white. Whatever name fits the color best, the important point is that it’s easy on the eyes. The paper is also described as water and tear resistant. I’d agree that it does have some water repellency, but it didn’t seem to take much more effort to tear than the decent copy paper I have. When it does tear, it seemed to do so neatly without many fibers showing along the tear line.
How does the paper perform? Well, it depends. For most pen and ink combinations it performed well and felt smooth. For a couple of pen and ink combinations it was more or less, as the kids might say, epic fail. Let’s take a look at pictures of particular pen/ink combinations.
First, my go-to-non-fountain-pen-of-choice, the Pentel Energels. I’m happy to say that the Energels took to the stone paper like a fish to water. This was especially true of the wider 0.7 mm point. In my experience, Energels write well on most paper surfaces but they felt particularly smooth on the stone paper and laid down a solid and consistent line.
Unfortunately, the dry times for the Energels on the stone paper were less than ideal. Energels are, in my experience, the fastest drying gels pens on the market today but something about the gel chemicals and the stone paper inhibits drying times. Regardless, there is smearing evident, even at the 10 second mark. That said, the writing experience is so smooth with the gel/stone paper combination that I might be willing to take my time writing and enjoy the ride.
What about fountain pens? Well, the few that I tried did not fare particularly well. My fine nib Kaweco AL Sport with Kaweco Blue did reasonably well. The writing was smooth but there was a touch of feathering on a letter or two. My TWSBI Mini, also with a fine nib and sporting Kon Peki, was less successful as the sharper point of the TWSBI dug into the stone paper a bit. You can see the digging in with the “T” of TWSBI in the pictures below. My Parker Vacumatic (also fine, also Kon Peki) was the one epic fail of the lot. All in all, I think good results could be obtained with a rounded fine nib and less slippery inks, but I did not immediately find a fountain pen/ink combination that worked like a charm with the stone paper.
Let me finish with the pen/ink combinations that took to the stone paper best. Hybrid and ballpoint inks did very, very well on this paper. Color saturation was amazing (on par with gel inks) and the dry times were nearly instantaneous. I think I can use a touch of chemistry to explain why the ballpoints worked so well. Apparently, the stone paper is made with 80% calcium carbonate and 20% non-toxic resin (I’m guessing these are weight percentages). Ballpoint and, to a less extent, hybrid inks are oil-based (i.e. hydrocarbon) media which I suspect bind effectively with the resin (i.e. hydrocarbon) of the stone paper. Interestingly, my Lamy rollerball (water-based ink) also wrote nicely and dried quickly on the stone paper but a post-writing water test showed some differences. The water-based rollerball ink and the gel inks smeared noticeably after dabbing with water but the hybrid and ballpoint inks held up great.
For what it’s worth, I also used some pencils on the stone paper. Very sharp and hard points dug into the paper too much, but softer/wider leads wrote smoothly. You can see the evidence of digging into the paper by the bits of embossing on the back.
Let’s conclude. Fountain pens and inks? Probably not. Gel pens and inks? Yes, but take your time to avoid smearing. Rollerball inks? Yes (but avoid water as always with rollerball inks). Ballpoint and hybrid inks? Yes, absolutely, my goodness yes! In fact, I decided to back the Kickstarter project for the Da Vinci Notebook based solely on the positive results I saw with ballpoint and hybrid inks. Backer options start at $12 on Kickstarter so trying the notebook for yourself won’t cost too much.
On a related note, Oxford makes a stone paper notebook that is available from Walgreens of all places (Sorry, I can’t bring myself to put a link to Walgreens on my blog). After playing with the Da Vinci Notebook paper sample, I ran over to my local Walgreens and got lucky. The paper in the Oxford book does have a similar texture and also provides a smooth writing feel. However, the Oxford paper is noticeably thinner than the Da Vinci Notebook sample. In fact, the page beneath the current page does become slightly embossed from writing in the Oxford notebook. I’m happy to have the Oxford notebook to play around with more stone paper, but I’m hopeful that the Kickstarter Da Vinci Notebooks will be a clear step up in quality.
A sample of the stone paper was provided to me free of charge by the creator of the Da Vinci Notebook Kickstarter project. Opinions and perspectives are entirely my own.
