Eco-Friendly Practices

We are a small, woman-owned and run business operating out of a solar-powered facility in Southern Oregon. We also double as a used packaging drop-off site for local residents and businesses. We use 100% post-consumer recycled packaging, home compostable paint pouches and recyclable glass and aluminum bottles for our products.

We give back by donating to "One Tree Planted" and "Rogue Climate" every month and continue to donate to various humanitarian and environment causes throughout the year.

Generally, all orders are shipped using zero-waste packaging and materials. Our shipping department uses paper stuffing and biodegradable paper tape, with the exception of shipping glass, as noted in the product descriptions for products made of glass.

Return Policies

We offer full refunds on any defective or damaged products. We also offer full refunds (less shipping costs) on elective returns if the product is in re-sellable condition and the return has been made within 3 months of the purchase.

Shipping Policies

Free Standard Shipping on orders above $100 for U.S. customers.

Orders containing in-stock items are typically processed within 2 business days from when we receive the order during operating hours. If a purchase contains out-of-stock or pre-order items, we will ship the order once ALL items are available and it can be fulfilled completely. Once an order is shipped, you will receive a confirmation email with tracking information; please save this email in case of any issues with your order.

After a package leaves our facility, it becomes the responsibility of the contracted carrier to get it to you. Any issues or problems that arise must be resolved with them directly. For USPS orders in particular, we've be instructed that it is best for the recipient to first speak with their local post office regarding any concerns.

Additionally, you can monitor your shipment or file a claim for lost mail with each of the carriers we use: U.S. Postal Service, UPS, or FedEx.

We work hard to ensure orders are processed and received as quickly as possible, but unfortunately, we're unable to locate lost or delayed packages. We recognize errors happen and ask for your patience in those circumstances, but we will not ship replacement items or issue refunds until a formal determination is made by the carrier. Please use the resources outlined above to seek resolution if needed.

 

International Shipping

If you’re ordering from Europe, Canada, Australia or New Zealand, please click the appropriate link to visit the distributor for your region. We normally ship USPS International for international orders, and the order typically takes 2-3 weeks for delivery. Due to global constraints, shipping times may vary, and additional delays can occur due to customs inspections. Since we never know if a package will be held at customs, any import fees or taxes applied to the delivery must be paid by the recipient.
PRODUCT FAQs

Does it yellow over time? 
We sell walnut oil because it is less yellowing than linseed oil although there will be slight yellowing over time.

When mixing your own oil paint, many people choose to use Liquid Gold Hempseed Oil with the white pigments only (instead of walnut or linseed oil), so that the white paint will never yellow. 

A common cause of yellowing is called "dark yellowing" and happens when pieces are stored in the dark for too long. The good news, though, is that placing the art piece back in direct sunlight will reverse the yellowing. This reversal takes anywhere from 1-7 days.

How long does it take to dry? 
Walnut oil dries slowly and can dry to the touch between 4-14 days depending on the humidity of your area, the type of pigment used and how thickly it was applied.

Is it refined? 
Yes. It is pure, expeller pressed walnut oil, so no other chemical or oils are introduced in manufacturing or bottling (when it is refined it is naturally "bleached" with clay which is just a natural filtering for color and clarity and there should be no allergen potential because it is refined). No hexane or solvents are used at all. 

How does it compare to linseed oil? 
You can use linseed oil interchangeably. We use walnut oil because it's higher quality and is less yellowing over time. But linseed oil dries faster which some people prefer. 

How does it compare to poppyseed oil? 
Historically, some painters mixed their white pigment with poppyseed oil instead of walnut or linseed because it never yellows and is the clearest of all oils. 

How does it compare to sunflower oil? 
Sunflower oil can be used but it dries much slower than walnut oil (which already dries pretty slow) and some sources say that it may discolor your painting or yellow over time. 

Is it flammable? 
All natural oils are potentially flammable if left on a rag in a hot area. It's suggested that you store oil soaked rags in a metal bucket with a lid and submerge in water if you're not disposing of them right away. Artists have many techniques of safely storing or disposing of their soiled rags - you'll find a lot of tips on google and artist forums.  

Can it be used for a wood stain? 
Most woodworkers who are staining outside wood furniture just mix our natural pigments with walnut oil and brush it on and then wipe with a dry rag. If you want the paint more opaque just add more pigment or don't wipe with the rag. It will bond well with the wood. It will completely compost and biodegrade because it's just earth and oil. Here's a tutorial with other natural wood staining recipes as well. We also sell a Natural Wood Stain & Varnish Set.

Has changed my art practice:pray:

I switched to walnut oil and it has changed my art practice. It is so smooth I really have come to further appreciate the beauty of pigments. I used to lay paints on thick and it occurs to me now I was reaching for something I now have with the pure pigments and walnut oil (making my own too, thank to Natural Earth Paint's) I am using smaller brushes, working thin. It's wonderful. Total convert. Made the switch initially because walnut oil's fire point is so high it isn't considered combustible. Temps have to be more than twice as high as for linseed oil, for example, before it combusts. That's added safety for my studio, my garage where the garbage bins are, and the landfill. We don't need more fires!

Great Walnut Oil!

I wanted to use something non-toxic to thin out my oil paints while painting and this works great, I will defiantly keep using this product.

I love it! I switched

I love it! I switched over from linseed oil and walnut oil is so much easier to work with and doesn't have an odor. The only issue is that I wish that it come with a pouring spout. It's hard not to waste it when it doesn't pour precisely out of the glass bottle. It would be so great if it came with a spout!

the perfect medium

What do I like most about the Walnut Oil? It is non-toxic, to me, to those who happen to be near when I paint, and to the earth.

I also like that I'm painting with the earth, and walnut oil is a part of that!
