I recently tested the multimedia mineral paper made by Yasutomo. In what follows, I speak about it and compare this paper with the TerraSkin. I also take the opportunity to show you some of my recent paintings created with the High Flow transparent acrylic ink from Golden on Yasutomo’s paper.

Yasutomo’s Paper

First, for those who do not know the mineral paper, it is mainly made with calcium carbonate. Also known as rock paper or stone paper, it is acid-free, without fibres, has a smooth finish and is produced without water, trees or bleach. It is suitable with a large variety of dry and wet mediums. To know more about this paper, I invite you to read this blog post written two years ago.

The Paper Is Very Thin (100 Lbs)

The multimedia paper made by Yasutomo is sold in pad of 20 sheets of 9 x 12 inches (22.9 x 30.5 cm). As for its weight, it is 100 lb (150 gsm). It’s thin, really thin. Naturally, it depends on your needs.

In spite of its low weight, the paper is resistant to treatment such as: rubbing, scraping, light sanding, alcohol, high amount of water, etc. Its soft and smooth surface seems identical and reacts the same way as the TerraSkin. However, the mineral paper made by Yasutomo still has its limits which are unfortunately directly related to its thinness:

  • Intensive sanding creates holes. I admit it, I’m hard on this type of paper and I like to create texture with sand paper. TerraSkin paper (340 lb) allows me to use this technique freely, but I must be much more careful with the 100 lb paper from Yasutomo.
  • Permanent creases are easily created. The sheets of paper remind me of the pages of a glossy magazine which must be handled carefully. Moreover, the block of paper that I bought has, without I realized it, one corner damaged. As a result, all the sheets were creased too …
  • It takes the texture of the painting surface. The thin paper makes so that if the sheets stay on a textured surface when working, it may take the texture of it. It can be a good point, but not always. In my case, I fixed the sheets with a painter’s tape on a large piece of Coroplast (kind of plastic corrugated board). In some spots, the light texture of the Coroplast appears on my paintings. On the other hand, if you like embossing, the paper might please you.
  • Uneasy framing? The paper is so thin that I wonder if it would be easy to frame a painting done on it …

Ideal for sketches and studies

This is why I think this paper is ideal for sketches and studies, but in my opinion, it is too thin to do works to offer to collectors unless it is mounted on a sturdier smooth substrate.

As for me, I’m going to scan my paintings and offer them as open-edition prints or use them to compose my next digital hybrid paintings. I plan to keep the originals for me because I find them too fragile.

The Alternative: The TerraSkin Pad or Large Sheets

Note that if you want to buy thicker and stronger rock paper, I suggest you look for the TerraSkin brand. It is often sold in pad of 25 sheets of 9 × 12 inches size, but they are 150 lb instead of only 100 lbs. In larger sheets, you may also find a thicker version (340 lbs, sold at DeSerres); this is the one I prefer.

PT & LB

By the way, TerraSkin paper is often sold with a thickness indicated in points (pt) – (1 point equals 0.001 inches). Here is the equivalent measure in pounds (lb) as shown on the Heart Stone website.

  • 16 pt = 300-340 lb
  • 12 pt = 160 to 200 lb
  • 10 pt 150 to 150 lb
  • 8 pt = 120 to 150 lb
  • 4 pt = 50-70 lbs

I hope this information will be helpful and I wish you great creative experiences with the mineral paper.

Thanks for your visit and see you soon,
