I bought some cheap multimedia/watercolor paper and used a brush to coat. I've used it to treat a couple hundred 8.5 x 11 sheets and I still have some left in the bottles. I wish I had tracked this better, but I think this will coat 300-500 8.5 x 11 sheets (way more than the bottle indicates). The results are great: very consistent and vivid. After prepping (about two hours of work) I made prints with 40 kindergartners and 8 adults in about 30 minutes, and everyone was pleased with the results. 1) I added water per instructions and fully dissolved the solids inside the bottles. I made a test example immediately after this and it worked fine, but the instructions advise to wait a day. I continued using the bottles for about a month and kept getting good results. 2) I covered a large work area in cheap plastic drop cloth. I was working with the blinds down, which left it bright enough to see. The less natural (UV) light, the better. However, I was able to work with regular indoor lights on while I did the coating and it seemed to work fine. 3) I combined a small amount of the solutions per the instructions. I used a digital scale to get equal amounts in a paper cup or bowl and used immediately. I would recommend mixing a tablespoon of each at first. This should coat 10-20 sheets of paper pretty easily, or perhaps a 5x5 area of cotton fabric. Mix only what you need. I didn't test how long the mixed solution could be left, but I think this should be done same-day. 4) Using a 3 inch foam brush, I coated several sheets of cheap 8.5x11 mixed-media/watercolor paper. It's about $5/60 sheets at hobby stores. I didn't price it online. The important thing is to completely cover the pages, but it doesn't need to be heavy or dripping. 5) I left the lights off while the paper dried for most of an afternoon. 6) I cut the paper down and stored it in manilla envelopes with a couple of extra sheets of construction paper to block out light. I don't know how long it will keep this way, but it works fine for at least 4 weeks. 7) I used glass from the hardware store and cut it ($8 tool) and taped the edges with duct tape. A 10x12 sheet of glass doesn't require cutting and costs about $5. A much bigger sheet can be cut into quarter-sheet sized pieces for about $1 each. Your willingness to work with glass and the size you want to use will determine the cost. The glass serves two important purposes: a) It keeps everything from blowing away. Even a little shifting will ruin the exposure. b) It keeps the objects flat against the cyano paper, giving a nice sharp silhouette and delicate details. Think of the shadow your hand makes when it is directly next to the ground or a wall, and then how fuzzy that shadow gets as you move your hand farther away. That sharpness of focus is the principle at work here. 8) I did this with kids using 4.25x5.5 quarter sheets, so I will describe that process. I folded a piece of heavy, dark paper and placed the cyano sheet inside and put masking tape on the outside. We had no trouble working briefly in the shade. However, these sheets can't be left outside in the shade for more than a few minutes or they will start to develop. Keep them in something like a folder before exposing. Kids wrote their names on the back (white) of the cyano sheet and the masking tape of the folder. 9) Kids collected their nature objects and opened their folder in the shade to arrange them on their cyano sheet. Kids were given a plate of glass to make a "sandwich:" cyano paper on bottom, nature objects next, glass on top, everything in the folder held careful and flat. 10) Once everything was arranged, the folder was moved to a sunny area and opened up to expose the cyano paper. I would stand with my shadow over it at first while I made any necessary quick adjustments and then moved everyone away for the exposure time. Bumping into the paper could be disastrous. 11) The paper can be exposed for about 3.5 minutes on a sunny day. On cotton cloth, 6 minutes seemed like a better length of time for photographic exposures. Using a black light inside, it needs to be just a few feet away for 10-15 minutes (if it washes out later, it was underexposed). 12) Once the time was up, we quickly stuck the papers back in the folder to stop the exposure and be ready to wash. 13) I used vinyl gloves when rinsing large projects, but I didn't get any stains just rinsing single sheets by hand. This should be done in the shade/artificial light, not in the sun. My advice is to get a paper plate or disposable baking pan filled with water and let the sheet soak and change the water 4-6 times over 2-3 minutes. For a large group project, create a line of 6 pans and run sheets through the pans 3 at a time for about 30 seconds each, shuffling them down the line in small batches. You can rinse 40 sheets in less than 10 minutes this way. Near the end of the washing process, use a small amount (a drop on a plate of water or a few drops in a pan) of hydrogen peroxide and watch the picture turn dark blue. Then rinse the peroxide water out in the final wash. The end result should be fairly stark deep blue and bright white. If the white looks ivory or yellow, it can probably be soaked/rinsed a little longer. If the blue is faded, it probably should have been exposed longer. I've also done this on smoothly sanded wood and left to soak/rinse for 10-20 minutes with good results. 14) The best way to dry the paper is hanging from a string with clothespins or letting as much water as possible drip off and then lying flat on a paper towel. DO NOT place a paper towel on top of the cyano paper. The color tends to leach/bleach during drying this way. I left mine in the sun to dry without ill effects. Read more

悪い製品ではないが、調合したら1時間が限度のような気がする。私の場合、調合してから長く置くと沈殿物が生じた。画像も荒れるように思う。しかし、手軽に結果を見るには良い品と思う。アマゾン内でも価格がまちまちだが、安い（増感キットだったか）ものでも同じものが届く。上手に使えば、これだけでもかなりな面積を塗ることが出来る。刷毛は無駄が多すぎるのでガラス棒が最適。ブラシ痕をあえて付加したければ刷毛だろうが、刷毛は混合した薬剤をそっくりそのまま紙に展開できるかというと、一概にそうとも言えないように思うので、やはりガラス棒に分があると考える。 Read more
