Ox gall is gall, usually obtained from cows, that is an ingredient in bile soap and mixed with alcohol and used as the wetting agent in paper marbling, engraving, lithography, and watercolor painting.
Should I use distilled water for watercolor painting? It is a greenish-brown liquid mixture containing cholesterol, lecithin, taurocholic acid, and glycocholic acid. Many artists believe that using distilled water for their watercolour paintings can make a tremendous difference to the quality of their artwork. Some water may be contaminated and effect the colour of the paints. Using distilled water guarantees that your paint will be of the correct tone and consistency. Gum Arabic As it is obtained from acacia tree, it is also referred to as gum acacia. Unlike xanthan gum, it contains glycoproteins in addition to polysaccharides. There are many substitutes for photo flo out there. Gum arabic is colorless, odorless, and highly soluble in water. I was not aware that Sistan had any surfactant in it, and I also thought that it was recommended that the print be rinsed after use of Sistan. Since Sistan contains a thiocyanate salt, I would personally want to rinse it before drying to prevent crystals from forming if nothing else. Gum arabic is the binder for watercolor, so when using ox gall one is actually using both ox gall and gum arabic.

Many do.It happens more often with less expensive paints but some professional grade colors can crack just because of the pigment nature and the amount of binder used to make the color. Most bottled "drinking water" is just tap water in a jug. If you're that concerned.do some homework on your local water supply, and maybe do your final rinse with distilled water. These traces won't hurt you when you drink it (it's bacteria that bites), but they leave residue on your film when it dries. that comes with tap water from your film. Photo Flo is a final wash/rinse to remove the minerals etc. If you want to experiment on your own, go right ahead.īut.all this is really about trace crap in your water. Even with that volume, we decided to keep buying Photo Flo and not risk the experiment on other people's film. We ran about 300 rolls of 35 on an average day. The only reason this conversation came up at work was because we were a very very busy lab, and always looking out for a way to save/make a dime. Recipe above gives you a lifetime supply of course.Įarlier post on this thread was wise.
It adds a slippery element that prevents spotting. I heard about this recipe, but never used it.ĥ gal water (danger.your water might not be as clean as you think.)Įvidently the key is the glycerin. Many decades of work in commercial/pro labs. The fact that Kodak doesn't use it should tell you all you need to know. If detergent or soap worked as a wetting agent then Kodak would use it. The bottom line is - use the proper stuff. It tends to leave the neg along with the water - any residue is undetectable. This compound has a relatively small molecular size, is chemically inert and is pH neutral. Wetting agent is normally ethylene glycol (it's used in car antifreeze). People who use soap or detergent and claim it works fine usually use it in such incredibly low concentrations that it does not actually do anything. In both cases they have to be used at quite high concentrations in order to work effectively and this results in a sticky coating of soap/detergent remaining on the neg. In addition, detergents contain other compounds designed to do different things - remember that they are designed for washing greasy dishes - which themselves decompose. In addition, soap reacts with the dissolved salts in tap water to form an insoluble scum which can end up on your neg.ĭetergents are manufactured from oil and are complex long chain molecules which again can break down over time. The mixture decomposes over time to release sulphur and other nasties detrimental to your negative.
To make it pH neutral you have to add an acid. Soap is made from animal fat and hydroxide.
