How to make turpentine?

Welcome to the ultimate guide on how to make turpentine, a volatile organic compound that has been used for centuries in painting and varnishing. Before we dive into the details, let’s clarify one thing first: Please do not try this at home! Making turpentine is dangerous and requires proper equipment, ventilation, and expertise.

Now that we got this out of the way, let’s proceed with caution and humor. This article will take you on a journey full of twists and turns as we explore the history, chemistry, and practical aspects of making turpentine from scratch.

Part 1: The Origins of Turpentine

Turpentine has been known since ancient times as an aromatic resin obtained from pine trees. Its name comes from the Latin term terebinthinus or terēbintina resīna – meaning “resin extracted from terebinth trees.” But why did people bother collecting tree sap in the first place?

Well, it turns out that turpentine had many uses beyond its pleasant scent. In medicine, it was considered a cure-all for various ailments such as constipation (yes, seriously), coughing (maybe), or kidney stones (nope, sorry). It was also used as a solvent (hurray), fuel (boomshakalaka), lubricant (insert joke here), or insecticide (kill them all, except bees).

But perhaps its most famous use is in art. Renaissance painters like Leonardo da Vinci or Michelangelo relied on turpentine (and other solvents) to mix their pigments into smooth colors and create illusions of depth and perspective. Later artists like Vincent van Gogh embraced its strong odor (“smells so good,” he wrote (who said artists are normal) ), while contemporary ones might prefer less toxic alternatives (bah, boring).

Part 2: The Chemistry of Turpentine

If you’re a chemistry geek or just curious, here’s some basic info about what turpentine is and how it works. At its core, turpentine is a mixture of organic compounds called terpenes, which are produced by pine trees as part of their defense mechanisms against insects and diseases.

Now for the hard(er) part:

  • These terpenes include alpha-pinene and beta-pinene (two types of monoterpenes), as well as other volatile molecules like camphene or limonene.
  • When distilled from raw sap or wood chips, these terpenes evaporate at different temperatures depending on their molecular weight and structure.
  • The resulting fractions can be further refined to produce three main types of turpentine: gum turpentine (has more cyclic hydrocarbons), steam-distilled turpentine (has mainly acyclic hydrocarbons), or sulfate turpentine (processed with concentrated sulfuric acid).

Boring stuff? I thought so too…

Part 3: Ok, Let’s Get Real – Can You DIY Turpentine?

The short answer is no. Making your own turpentine requires specialized equipment, such as stills, retorts (not those ones), condensers (not the cooler kind), oil separators (no, not for French fries either!), vacuum pumps (nothing sexual here!), and safety gear such as gloves (kinky?), goggles (cool shades bro!) and respirators (this one IS important).

Besides the initial investment in materials, there are several risks involved in making your own solvent:

  1. Fire hazard – since most methods involve heating up flammable liquids like steam-distilled wood oil.
  2. Toxic vapors – improper ventilation can lead to respiratory problems or central nervous system damage.
  3. Chemical reactions – turpentine may react with other substances in unexpected ways, producing toxic gases or acids.

So again, do not try this at home! You might end up worse than a DIY haircut…

Part 4: But What if I REALLY Want to Try?

Alright, let’s say you’re still feeling adventurous (or reckless) and want to know more about the actual process of making turpentine (you masochist!). Here are some basic steps that most sources suggest:

  1. Collect fresh pine sap by cutting into the tree bark or attaching containers underneath it. (Bonus: avoid hurting trees by using eco-friendly taps such as those made from recycled plastics.)
  2. Filter out impurities such as bark particles, insects, or mold spores by heating up the sap and then letting it cool down slowly to let debris settle down.
  3. Distill the filtered sap in a retort over an open flame until the terpenes evaporate and condense into liquid form in a separate container.
  4. Refine further according to your preferred method (steam distillation is said to produce less odor but also less quality compared to gum turpentine).

Again,DO NOT ATTEMPT THIS INSANE EXPERIMENT OR ELSE…

Part 5: Conclusion

In conclusion, making your own turpentine is not only risky but also unnecessary nowadays when there are plenty of commercially available options that are safer and more consistent in quality (sorry hippie, times have changed). However, learning about its origins and chemistry can give us insight into how humans have interacted with nature for millennia.

Turpentine may no longer be hailed as a panacea or a miracle paint thinner anymore (unless you’re Leonardo da Vinci’s ghost), but it still has its place in our cultural imagination as part of our artistic heritage.(and don’t forget, an interesting conversation starter at parties!)

So let’s raise our imaginary glasses (we can drink whatever we want since this is all in our minds) to turpentine – the (not so) great and powerful solvent that has inspired countless artists, chemists, and hoodlums throughout history. Cheers!

Part 6: Glossary

  • VOCs – volatile organic compounds
  • monoterpenes – a class of terpenoid molecules composed of two isoprene units
  • hydrocarbons – organic chemicals consisting solely of hydrogen and carbon atoms
  • distillation – a separation process based on heating up liquids or solids into vapors and then cooling them down into condensates.
  • flammable – able to set on fire easily due to its high flash point (temperature at which it catches fire).
  • stills/retorts/condensers/etc. – various types of apparatus used for separating or purifying substances by heat-based methods.
