Question about using a modified coffee stirrer on paints

Recommended Posts

Hi, i saw on amazon a paint mixer/stirrer that its similar to the ones for drinks or coffe, only this one is for hobbist paint, its brand is badger.  I custom made one that its really similar to this one and actually fits inside reaper bottles.

 

I just used it on some reaper and vallejo paints that i have for a while, some of them especially the vallejo ones were kind of gummy with pigment on the bottom, i used my custom stirrer  and solved the issue! .  Thing is, it works very well, but on reaper i feel as if it makes the paint less dense, and in some colours like pale saffron and lemon yellow this is more evident, is covers well but feels a little similar to watercolor in its consistency . Maybe its because the stirrer is quite potent and spins very fast, so wanted to ask help to anyone that have experience using a stirrer for mixing paint and also ask Anne Foerster or some people that actually work with the composition of paint, if any of you are seen this, please help ! ;) will really appreciate it.

 

If i use this product can i harm the reaper paints that i have? Also  on the other hand mixing the paint like this can have any positive effect as well? 

 

Thanks for all the help, i always count on this forum when i need some important facts or tips ;)

Never having used it, I can only offer the following:

 

Fast mixing can introduce air into the mix.  This isn't a problem for air brush paint, since it all gets dispersed via air, but it may give the impression that the paint is less dense than normal.  You may have micro-bubbles in your paint that change how it is applied, although I can't imagine it would change the paint a lot.  Fast speed alone won't cause the paint to become less viscous, as the binders and such in the paint are already ground up, and you aren't going to add liquid unless you actually add liquid.

 

I just use the other end of my paintbrush to stir up the sediment, if necessary, and then give it a good shake or seven. 

 

Good luck.

Thanks ! Any feedback is welcome as its the first time i use this thing too :) i feel its less dense but as you say maybe its because of bubbles, although some people says that bubbles are bad for the paint and it worries me a little, there are not a lot of them but still. I usually paint with a brush , do you think it affects my paints too?

If you're not seeing bubbles on the brush or painted surface when you paint or a rough surface when the paint is dry, you should be fine.

There are some bubbles on the pot, and also when i put some paint in my wet palette, but apart of that i only see but a few on the mini when i paint, and they dissapear after a while.

Plus the colors you have mentioned are a bit on the translucent side anyway so coverage is weak and takes several coats.

Be careful about painting with bubbling paint. The surface area to mass ratio of the bubbles is very high, so they will tend to dry out significantly more quickly than the rest of the surface. And if that happens, you can end up with a rough surface.

I think is something with the yellows in the reaper line isnt it?

I stir my paints.  Usually I use chopsticks, but for wee little things like Reaper dropper bottles I use bamboo skewers.

 

It's faster, more thorough, and more reliable than shaking.

 

Even pure pigment paints, such as I use most of the time, can get some separation over time, especially if the pigment is notably heavy (Titanium White, for example, is pretty heavy and in paint it tends to settle below a layer of pure acrylic medium if left undisturbed).

 

Electric stirrers, though, I don't know.  Bubbles / foaming can be a thing.

There are very few true yellows or reds with good coverage. The best such pigments are cadmium salts, which have toxicity issues. (Love me some Cadmium Red or Cadmium Yellow.) Because of the toxicity (and price), other pigments are usually used, especially where there's a real chance of consumption. There are tricks that you can use to get better coverage, for instance: cover with a brownish yellow like a yellow ochre first, then paint with a more translucent, brighter yellow.

I sent a mail directly to Reaper customer service and they told me that the stirrer dont affect the paint, although didnt explain too much .

Thanks for the tip about yellows, will definetely try it!

Reaper's Palomino Gold is a pure yellow iron oxide pigment and makes an excellent undercoat for brighter yellows (lighten with a little white if necessary).

Stirring will not change the ingredients of the paint, just how well they are mixed.

      I don't have a blog, and I am not veteran or post enough content to justify making one - so while these musings may be better served in that format, I will leave it here for anyone who is interested to view and chime in. It just so happens that my best friend happens to work at Rustoleum as a colorist; so lately I have been picking his brain since he has an extensive knowledge about pigments, paint make up, and the chemical intricacies therein.
       
      As I have delved further and further into the hobby, I have been looking more into the deep subjects of color theory and how paint is made/composed. After reading James Gurney's Color and Light, as well as Michael Wilcox's Blue & Yellow Don't Make Green, I was really intrigued about what exactly paint is and how exactly color interactions work. Now I am guilty as the next person in owning WAY too many paints - not to say anything about minis!
       
      While color mixing may seem irrelevant to some, understanding how paints function can help even those of us who own a complete gamut of convenience mixed colors. This post is about exploring more of the technical and "scientific" aspects of paint and color theory to hopefully assist others in understanding the what and why of paint.
       
      Rethinking Paint Colors - Subtractive Color:
      Up until recently, I have always viewed the primary colors as Yellow, Red and Blue, and with those you can mix secondary colors; Green, Orange, and Purple. While this is technically true after a fashion, the difficulty lies with pigments themselves. Pigments do not actually *contain* color. Instead, they absorb most of the light spectrum *except* a specific wavelength of color. As Michael Wilcox states, "Of all the pigments available to the painter, none can be described as pure in hue. There is simply no such thing as a pure red, yellow or blue paint." That means chemically, there isn't a paint pigment out there that returns a pure Red - unlike in say digital art where a specifically purely calibrated hue can be made, paint is limited by the properties of the physical pigments themselves.
       
      As Michael Wilcox theorizes with a colour bias wheel (bottom-right), primary pigments almost certainly lean towards secondaries. This follows the concept of the Munsell Wheel (bottom-left). You may have heard of a split-complimentary color palette, and this is the reason why. Artistically, these have been described as "Warm" and "Cool" versions of the primaries, but scientifically, they are colors that absorb or reflect more of a particular wavelength. There are Violet-Reds (Cool Reds, often called "Crimson") and Orange-Reds (or Warm Reds, that lean more towards Orange), Violet-Blues and Green-Blues, and Orange-Yellows and Green-Yellows.
       

       
      One the concepts to understand when mixing paints is that you are not creating a color, but rather you are effectively destroying colors and what remains is what is returned to the eye. Referencing the above color bias wheel, if you were to mix a Violet-Blue and a Violet-Red together, both containing pigment(s) that return a great deal of Violet wavelength, the little remaining Blue/Orange and Red/Green wavelengths in each pigment would cancel each other out, leaving the Violet behind.  This would yield a more saturated or more pure hue of Violet. Conversely, mixing a Green-Blue and a Orange-Red ("Warm" Red) would be a very desaturated Violet, with more of a gray tone.
       
      Keep in mind that this doesn't make a color "bad"; desatured tones by including more complimentary colors is a very useful tool! In fact, for making shadows, using a great deal of complimentary colors to desaturate is a great technique. The problem is when these colors come about unexpectedly; after all, you can have a very "intense" Red and a very "intense" Blue, but mixing them may not produce a very intense Violet if they are "moving away" from each other.
       
      Now that is all being said, it is time to forget it...sort of. RGB is based upon the concept of Additive Mixing, or how colored light interacts. With additive mixing, fully saturated Red/Green/Blue light will produce White light. However, in paint pigments, it should be pretty obvious that mixing pigment primaries of Red/Yellow (or Green)/Blue together will not yield White. This is due to Subtractive Mixing, where pigments effectively destroy each other ala Thunderdome in Mad Max, and only the survivors reflect light back.
       
      A more modern approach to color theory and pigments is CMYK or Cyan, Magenta, Yellow and "Key" (or commonly known, Black). Adding these colors into the standard primaries gives us the "Yurmby" wheel. If you have looked at a color printer, for example, the colors used are NOT Blue/Red/Yellow, but rather Cyan/Magenta/Yellow. This is because due to the subtractive nature of pigment/ink mixing. These colors present a larger printable gamut (i.e. range) of color; for example, without White, it is difficult to produce a Pink tone with Red vs Magenta. A thin Magenta will read more Pink than a thin Red.
       
      Printers do not use White ink and instead leverage the paper for white, effectively printers are printing in an underpainting style. However, we as artists DO use White pigments and this makes things a bit more complicated as we do work with Tints (White) and Shades (Black).
       

       
      Like most science, the direct answer regarding an accurate color wheel is: it is complicated. For observable light, there is a bit more consistency and repeatability. However, when working with "tiny wavelength absorbing/reflecting mirrors" of pigments, things become a bit more complex. Additionally, there are other aspects that that go beyond the basics, such as the effect of specular and perception of color. It gets really heady when you start dipping into Kubelka-Monk Theory and K/S.
       
      Paint Composition:
      Most paint is made up of 3 parts:
      Pigment - particles that absorb and reflect certain wavelengths of light.
      Binder - The 'medium' or 'glue' which holds the pigment in suspension and forms a film. For acrylic paint, this is the actual acrylic part.
      Solvent - The liquid that allows paint to be viscous; as it dries, it allows the binder and pigment to harden forming the film. For acrylic paint, the solvent is water.
       
      Adjusting the ratios of these can have some interesting, and sometimes disastrous effects in terms of the stability of the paint. For example, introducing too much solvent, and the binder and pigment lattice structure can break apart. This can cause "coffee staining" or splotchy spots where the bonds pull apart, leaving areas without a film at all.
       
      The pigments in paint are held in a suspension. Like hot chocolate mix, there are tiny particles that are suspended in a liquid. Given enough time or evaporation, the liquid will leave these granules behind. If you have ever mixed a packet of Swiss Miss cocoa, you know that the mix can settle at the bottom - and that attempting to add dry powder to a liquid is more difficult than adding a liquid to a dry powder. This is another reason why mixing your paints is important because it is easy for the heavier pigments to tend to settle out of the binder/solvent solution.
       
      Speaking of solutions, that is the main difference between paints and inks. Inks, specifically alcohol inks that use dyes, are a solution. The staining dye actually becomes homogeneous with the liquid. Just like dissolving sugar or extracting coffee/tea, there isn't any particulates that separate out. However, most dyes are not lightfast - a property that will be discussed in more detail further. Acrylic inks that use pigments are not "true" inks insomuch as they are composed just like an acrylic paint. The difference being the smaller size of the pigments and the viscosity of the binder/solvent being much thinner.
       
      Paint Additives
      Outside of the 3 main components for paint composition, there are also some optional additives that some manufacturer's include in their paint. These can be things such as:
      Extenders/retarders, which delay the setup of the paint film, allowing for more mixing to occur before drying. Thinners, which dilute the pigment to binder ratio, usually increasing translucency and viscosity - commonly this is done with water for acrylic paints. Flow Aid, which reduces the surface tension of paint, allowing it to flow more easily and level - Reaper is known for adding a bit of flow aid into their formulation. Opacifiers, which increase the opacity of a paint - usually some type of calcium or bicarbonate. Matting agents, which reduces the glossiness of acrylic medium. Fillers, which are commonly used in student or inexpensive paints to reduce cost and add mass without adding more pigment.  
      You can add some of these additives yourself to your favorite brand of paint to adjust the handling qualities. The most commonly added is solvent/thinner in the form of water to "thin your paints" to reduce the viscosity and lower the overall density of the paint, building up multiple thinner layers of paint films in a "layering" fashion.

      I'm a fan of the Scale 75 paints, they have a new range called artist colors.
      The paint comes in tubes.
       
      I wonder if anyone has tried these?
      You're thoughts on these?

      My husband and I run the Paint and Take table at a local convention, Recruits.  It's held at the high school, admission is free for all area students, games are child friendly, etc.  We get really good turnout.  The paint table is free for kids of all ages, even grownup kids, and it is funded entirely with donations.  All of the figures, all of the paint, water cups, brushes, etc come from the wonderful community we have here, from the internet, and from vendors.  It's typical for me to arrive early Saturday to set up and find one or more anonymous boxes of figures or paint waiting.  A couple of years ago at Reapercon folks helped fill a box with mouslings for me to give away.  I could not do this without the support I get from the painting and gaming community. 
       
      So here is this year's class:
       
      (BTW, if you got stuff in your Bones4 core that you do not want, find me at next year's Reapercon, I will see it goes to a good cause)
       
      This is our table about ten minutes after setting up.  Busy the entire day. 
       

       
      Some of the fine works of art created by the kids who participated.  They look forward to this all year. 
       

       

       

       
      Got to pick up more baby dragons next year. I only had the one and it resulted in crying. :(

      Good morning guys! 
       
      Q: if buying one of the reaper core sets (108 bottle set), what's the main difference in them? 
       
      I'm looking into buying a complete paint set. I've been doing a ton of research and have settled on a reaper core set (i already own several reaper paints and love them).  I know that everyone suggests a blend of several companies based on which has the best,  e.g. yellow,  or metallics. I just want to make it simple, buy a set and build from there. 
       
      I'll mostly be painting 40k and privateer press models with some terrain and 3d prints mixed in (i have a cheapo set of acrylics from Michael's for large terrain and 3d prints).
       
      I've also considered the Vallejo Model set, and Army Painter Mega Set.
       
      Thanks in advance!

      A noobish question, should I thin down reaper washes? Or are they ready to use out of the dropper? 
      Sorry if this has been asked.
