    Question

    ‚ÄčThe papers in question are made of calcium carbonate with a binder that makes it into a beautiful vellum smooth absorbent surface. I have used this paper with casein paint and casein as underpainting with subsequent alkyd/oil paint layers. I first adhere the unprimed mineral paper to sanded ACM panel using acrylic gel medium or lineco. Since paper is just calcium carbonate with a binder, wonder about the longevity of this paper? papers by Mitz or Yasutomo companies. Acid free. Mineral paper also handles well for acryl gouache.

    I have no experience with either of these products. I did take a look at their advertisements and it appears that they are a mixture of calcium carbonate and a synthetic resin. Mitz specifically states 25% non-toxic resin. The idea is certainly interesting but longevity would depend on the stability of the resin and long-term flexibility of the sheet. It would also depend on the normal factors of appropriate absorption, etc.

    We will send your question to some of our moderators/ contacts in the paper and preventive paper/preventive conservation world.

    Here is what I have been able to find out about this product: "Made from 80% calcium carbonate bonded with a small amount of plastic, this paper can be used with watercolors, acrylics, inks, pastels, pencils, markers, and inkjet printers.

    Yasutomo Mineral Paper can also be embossed, hot-stamped, varnished, glued, and laminated. Water-resistant with a smooth finish, it still has enough tooth and absorption for all mediums. It will not buckle when used with the wettest mediums."

    I have no experience with this "paper" but it it is clearly super-absorbant.  So fingerprints and accumulated dirt and grime will be a problem in the future.  Like any other drawing on a ground... Any uncoated surface needs to be protected.
