How do you make oil paint?

I want to know how to make oil paint but if anyone knows how to make another paint please tell me. I need what I need to make it. Thank you.How do you make oil paint?
Making oil paint is not that hard. All you really need is linseed oil and pigments. You grind the pigment and slowly add linseed oil as you gring until its a thick paiste like soft butter. I remember once in art school we made paints by grinding down pastels and mixing it with dishwashing liquid. It was a primitive paint, though.


GoodluckHow do you make oil paint?
Actually Linseed oil purified and heated. But linseed is HIGHLY VOLATILE. It can blow up.


The old masters use to take linseed and add pigment and DAMAR crystals in proportions depending on the colour. The reason being for the DAMAR is that linseed will make your pigment transparent and it also CUTS the amount of pigment you need. Pigments were made of all sorts of things. Vermilion (Redish orange colour) was made from bugs crushed up. White was made from OXIDE from metals. HIGHLY TOXIC in the FLAKE variety.





To make paint you can try a water based. This is fun if you want to eat the stuff鈥?





Take some instant Gallatin. It鈥檚 ALL READY COLURED!!! Add some hot water slowly, (less than they say), until it is thick but still able to be picked up by a paintbrush and still able to be applied to paper. You can paint WHITE CHOCOLATE BARS as your canvas!!!! YUMMY!!!!
yes, mixing lineseed oil with pigments. Each pigment requires different quantities of oil, just add it little by little until you get a buttery consistency





I guess it can be easier to make tempera, you just have to mix an egg's yolk with the same volume of water. Pour and mix little by little. Then you add this mixture to the pigment. You can add more water to make it more fluid.





As pigments you can use any colored powder.





If you want lightfast paintings then you should buy professional pigments.





Most paintings before the XVI century were done in this way. look at Botticelli.





have fun!
You need:


Artist grade pigments


A sheet of tempered glass about 12';x18';


A muller, which is a glass pestle that you use to grind the paint


A palette knife


A tube or pot to contain the paint


Linseed oil. Light refined linseed oil is best.


Good ventilation - a vent hood if you can manage it.


Latex gloves and a respirator that will block out fine particulate matter.





Some pigments are highly toxic when inhaled or absorbed through the skin. Wear clothes that you will be able to step out of and throw right in the washer. All those warning signs on the tubes of paint about cancer agents -- they ARE NOT kidding so take the necessary precautions, especially when using cadmiums or cobalts. Do not, under any circumstances, do this in the general house - stick to the garage or mud room (if you don't have a studio) to minimize contamination.





By respirator I mean a high quality one -- Not a little paper mask like you use to paint the house but a real respirator with a filter.





The tempered glass will not break while grinding, but regular glass will shatter.





The bottom of the muller and the grinding surface of the tempered glass should be textured to improve the grinding contact. Sandblasting or chemical sandblasting agents do fine.





On one end of your glass, put a substantial pile of a pigment.


In the middle of the glass, put a small pile of pigment. Make a well in the pile.





Pour a little linseed oil into the well. Use the palette knife to start folding the pigiment and oil together. Keep adjusting the oil-to-pigment ratio until it is a thick mixture, folding with the knife. Pull from the large pigment pile on the edge of the glass, pulling it into the mixture.





Once you have it well mixed and fairly stiff, start grinding it with the muller by putting the muller on the edge of the mixed pigment and grinding in circles, working your way to the center of the pile. Grind it to get a smooth and buttery mixture. This takes some time and some fairly vigorous elbow grease. As you grind it the consistency will either get sticky and thick or thin and runny. Adjust appropriately with more oil or pigment as needed. The ground paint should be about the consistency of cream cheese for most pigments and smooth as butter.





Use the palette knife to tube the paints. Aluminum tubes are available from good art supply stores online. They look like toothpaste tubes with the back open and the lid screwed on. Scoop the paint into the tubes and tamp them down to avoid air bubbles, which will oxidize the paint. Leave about 1'; of tube empty at the top.





Use canvas pliers to crimp the end of the tube. Roll it several times, crimping each time to get a tight closing on the back of the tube.





The resources have a couple of art supply catalogs that should carry these supplies.





The outlay is not cheap but it saves money in the long run. Just mind what I say about the safety precautions, yo.
