Type_A_04_violin by komac1, on Flickr

Hi, can anyone tell me how to paint/varnish a violin like this and what exactly to buy. I need exactly the procedure, and types of paint that I need to achieve this (I found this picture on the internet), and where to buy the paint.

Thank you

you mean how to stain/varnish a violin just like that?

You'd probably have to talk to the guy who did it to know EXACTLY.

But it sort of looks like he started by staining or varnishing the whole thing yellow - and then added a brown stain and/or varnish, graduating it into the yellow at the center, carefully starting at the purfling (??) (perhaps he masked it there?) - but leaving the edges the origional yellow.

?

CT is correct, the only way to know how it was done is from the person who did it. But this color effect is called a 'sunburst' and you can see how it's achieved a this site:

It's not a traditional violin color effect, mostly it's done on plucked instruments like guitars and mandolins

I could be mistaken, but that looks very much like guitar lacquer to me. I don't think it is varnish...it also looks as though it was sprayed on, but I suppose it is possible it was accomplished by french-polishing.

Yeah, your probably right, I didn't think of spraying, but that graduation does indeed look like a spray graduation...

if you take a look at the youtube link I posted above you can see how the colors are spray painted on a guitar.

Lacquer is not thought to have very good acoustical properties for violin family instruments. But seem ok for guitars.

OK

you may find that its a little more complicated than painting, what are you thinking of doing, refinish one or one you made?

...I was thinking just to paint my new violin which is not completely made yet... but the transition doesn't have to be like this from brown to yellow, maybe it could be done by brush, and then polished somehow...

You can certainly get this effect with the "finger-painting" method. I don't know whether it will work with spirit varnish, but it certainly works with oil varnish.

At 3.59 of the video below you can get an idea of this technique:

On guitars the traditional way to do this is with a dilute alcohol stain and a rag, gradually wiping on the color around the outside, building the fade into the center, darkness towards the outside. Then when that dark border is right, plain amber varnish is put over the whole thing.

Antonio, what no one is saying is
1/ this is a hideous look that looks only a little better on a cheap guitar and screams out "low-price factory-made instrument"
2. it's never done on violins (the example you put up is the first I've seen)

Usually variations of color on violins follows the natural wear paths that an instrument gets through the passage of time.

Lacquer sounds fine on violins, by the way, if it's thin enough.

But;

We were thinking it. (I do believe)

HA HA! Ok so what would you suggest, if I want my violin to be brown, without these transitions, what should I put first, what last, I mean the coats of paint/varnish, and where to buy them... I painted a lot of things, including megayachts, wooden doors etc., but never a violin, so I would like to know at least what is the proper paint or varnish so that it doesn't ruin the sound...

The basic plan is to lay something almost uncolored as a base--it's considered bad for the wood to get stained as is common with furniture--violin makers call that "burned", when color gets into the wood. A little amber color to mimic age is OK, but not too much. Then after you have a good sealed surface, put on layers of varnish of the color you want--say, brown, in your case.

Spraying is common, if you have the equipment, and extremely easy.

Shellac, with it's original color in it, not "white" or bleached, is a good base. Then for on top of that, the normal thing to do is use either an alcohol-based varnish, or a linseed-oil based varnish, for the colored part. Alcohol varnish is very difficult to brush, very easy to spray. Oil varnish is easy to brush on. For colors, you can use anything that will mix with your varnish, doing tests until you have something you like.

If you want some sort of aged look, you can carefully remove color to copy age. For instance, I always remove quite a bit of color around the edge, outside the purfling, the corners of the head, etc. with steel wool, lightly. Then you can do more and more to mimic different states of wear. Look at photos of older expensive violins to see what people are trying to copy. The violins here, for instance: http://archive.music.ntnu.edu.tw/chimei/search.html

Forget about ruining the sound, it's trying to make it look like a real violn which is the issue.

As Michael said, shading of colours on violin varnish should mimick traditional wear patterns. Everything you do with a violin is OK as long it's been done in the past 300 years. But that's like saying in order to fly you need wings. Varnishing a violin isn't a paint job. I feel for you. If you take this quest seriously, you'll start to find out about grounds, sealers, spirit varnishes, oil varnishes, drying cabinets, ready-to-use commercial varnishes (which can go at well over $100 per 100ml), coloring matter, application methods - and heaven forbid, about making your own varnish. In the end makiing the violin itself may seem like an inconsequential preliminary.

Basically you need to decide whether you are trying to produce a violin or an excentric ornament. At this stage at least, you can't have both. It's like saying: "I know exactly what a Superhero Comic strip tooks like. How do I paint like Van Gogh?"
