A potter in ancient Rome would produce many soup bowls for sale, and if there were any flaws in the bowls, they might hide the imperfections and holes with wax. When the buyer got home and filled it with hot liquid, the wax would melt and the deceit would be discovered. So, potters began to use a slogan to describe their wares: Sine Cera. It means "without wax". It is the origin of the word "sincere".

I don't know about earthen wear pottery, but when you seal earthen floors with boiled linseed oil, it involves several coats, drying between coats, and then ,when the clay will take absolutely no more oil, a topcoat of beeswax (often heated with a heat gun, and polished).

In Kerala, India, we seal the pots with rice starches. After washing the rice, save the liquid. Thereafter after cooking the rice, don't throw away the starchy liquid (rice gruel). Mix these two liquids and soak in it over three days (every day freshly washed rice and gruel). Soak the pots in this liquid for three day. On the 4th day, rinse and dry in the sun. Next use some coconut oil and leave the for some time. It will soak the oil. Thereafter,pour some more coconut oil.and fry some coconuts in the pot. The smell will stay through out.

I took some time to realize why this video defined "old world" as just Europe and Middle East, until he said "other than glaze" and remembered how the silica-alumina based glaze became very dominant a lot earlier in East Asia compared to everywhere else. But it makes Indian subcontinent left out, so this was an interesting read for me. Rice is linked with pottery in Korea as well, mainly in maintaining them. Rice water is said to be a weak surfactant, so in Korea we wash porrous earthwares (those often used for fermentation) with starchy rice water. People avoid using dish soaps on them because the detergent can soak through and remain on those pots' porrous surfaces. Rice is "food-grade" by definition, and it's not only safe, but also absent of strong scent or aftertaste. Being it safe and subtle on pots should mean a lot, judging from how three test mugs fared in this video. Whether it is used as a sealant or a soap, it was cool to have known how different cultures use rice as a "food-grade" material to apply on cookware, thanks to you.

03:30 There is still a Greek wine today; the "retsina", whose origin, 4000 years ago, is the use of pine resin to seal the amphorae which were sent to the various trading posts of the Mediterranean Sea. The pine resin actually gave a particular taste to the wine, but also protected the wine from oxidation. This wine always has this particular taste well known to tourists in this country.

Hmm, smoky pine flavoured ice cream, I think I could go for that

I work a lot with pine pitch in pottery and can give a couple small pieces of advice to get more desirable results. First, you can put a slice of ginger in the pitch-sealed vessel overnight or for a couple of days to eliminate any odor. I have made decently large pieces and for some reason ginger just absorbs the bitter smell of the pitch very efficiently. Second, you can cook off any excess pitch by putting the vessels in the oven or near a fire at about 400F. The time it takes depends on the size of the vessel as well as the thickness of the pitch coating, but it should leave behind a very nice surface with any excess pitch burned away. You may even consider rubbing a rag saturated with pitch onto the vessel immediately after firing it rather than poring it into the vessel as you did in the video. The very hot ceramic will burn off any excess, leaving the pores completely sealed.

Where do you get your pitch? Do you perhaps make it yourself?

When sealing wood with linseed oil, best results are when you put wood in a really hot oil (100C-130C +) and keep this temperature until bubbles /mostly/ stop coming out of the wood piece. Which means that wood is fully saturated with oil. After that, dry it for a week or a month, preferably in a dry and sunny place. Maybe same would work for earthenware? It will require a ton of oil, a really big metal pot and quite a bit of time though.

If you use linseed/flaxseed oil to seal food or drink vessels, be sure it’s the edible kind. Flaxseed oil and linseed oil are the same thing, but (in the USA) the kind used for food is usually called flaxseed oil, and the kind used for furniture finishes and paint is usually called linseed oil (terminology may differ in other countries). “Boiled” linseed oil typically contains solvents and driers that are not food-safe. But the pure linseed oil sold as a food ingredient or dietary supplement is safe to use on dishes.

Wine enthusiast here: Pitch was definitely used in wine containers during Roman times. This was definitely detectable by taste; at least some winemaking in France was done both in 'pitched' and 'clean' variants, pitched for those weird Romans, unpitched for local consumption. It seems so have been an acquired taste, which, for the Romans (probably due to bad experiences pre-pitch), indicated quality. Kind of like chlorinated water nowadays, which apparently is preferred by Americans and French, but is actually disliked in my country (the Netherlands), because we have clean drinking water coming out of our taps without chlorination.

If you stored a light white wine in a pine pitch sealed amphora, the result might approximate *retsina* -- which is a Greek wine that's stored in pine barrels and picks up flavor from the pine resin. I've had this, and found it pleasant enough, though I'm not much of a wine drinker. I'd have hoped you'd allow several weeks for the linseed oil to cure -- I recall from learning oil painting (really forty years ago?) that oil based paints might take as much as a year to fully cure, and even the old oil based house paints (still in use when I was a kid in the 1960s, since completely replaced with latex-based, water-solvent paints) would take several days to cure enough to be safe to handle. Also worth noting that pitch (presumably from pine) was used throughout medieval times to seal "jacks" -- leather drinking mugs. These were used to drink whatever a traveler might get (which would be ale more often than anything else). Given the inconsistency of medieval beer before gruit was replaced by hops, however, it's very possible a traveler would never notice a flavor in the beer from the pine pitch.

John Plant over on the Primitive Technology channel uses porous earthenware to process clay. He starts by stirring clay-bearing soil into a pit filled with water and gives it a couple of seconds for the heavy particles to drop to the bottom, leaving the fine clay particles in suspension. He then transfers the suspension to a large earthenware pot where the water slowly seeps out leaving the clay behind. He uses a similar process to dry iron-bearing sludge.

I think the trick is to coat them then put them again on the coals, suspended so it dries out. That way, the pitch can polymerize and turn from resin into rosin. And it probably won't hurt the other sealing methods, either, to do. Edit: You might want to start a smaller fire nearby, too, to get the temperature high enough for the oil and pitch to fully polymerize into basically ancient plastic. And also you might want to use something like a piece of cloth to "polish" the surface in the same way you would with a buffing compound, again, all that before "baking" the result at high temperatures, so the oil and resin can turn rock-hard. Often, a mixture of resin and wax was used to get the melting point of the mixture lower, before it was baked to evaporate the wax and have only the resin leftover, as a glossy coating. Also, I'm not entirely sure if this works, but I think it could be, so I think it is worth trying: by mixing beach sand (silica sand) with lye (which was traditionally made from wood/grass/plant ash, so from potassium instead of sodium), you make waterglass, which you can use to not-really-seal pottery, then dry it out, then add an acid (i.e. vinegar) to separate the lye from the sand "shell", then carefully remove the liquid, then bake it again, or bake it for the first time. You would likely have to do this in a few steps, for example first the bottom then use some clay as a lid to keep the liquid in while doing the sides by marking a + and an x on one side of the cup so you can remove the lye 1/8 of the cup at a time, for the silica to precipitate and form a shell around the clay, which to cover the pores of the clay. If this is done before firing, it would likely be needed to let the clay dry so the silica layer properly bonds/adheres to the clay. I know this was not traditionally done, as far as I know, and it would have been a lot of effort for getting a glass glaze, but you might be able to get a glass glaze this way.

Such a blend is used in other traditional sealant applications, like canoes. I think the pitch adds a certain toughness while the wax adds fluidity/workability. Also pure beeswax would probably absorb and get saturated with oil and soften if not outright dissolve if used in long term contact. Pine or polymerizing oils might be superior for sealing in oils in that regard? Not sure but the best sealant probably is application dependent. But for coffee mugs im also convinced of the bees wax!

Birch tree resin was used in many things as glue and sealants due to it being more stable and 'flexible' compared to pine resin. Pine resin over time can crack especially in cold weather. It's hard to make Birch resin in comparison as it has to be made in a vacuum but it's been around since the Neanderthals as they used it too. The mix of wax and resin it to keep the seal 'flexible'. You could potentially get an incredible long lasting seal by using birch resin with a small amount of bees wax.

super well made video! love the time stamps and depth of testing 😊

Ooh I love using beeswax for everything - I'll bring it when I fire my first pots! Assuming they fire correctly and don't break 😅 I've been binging your videos since I sculpted my first pot with river clay & had no idea how to fire it. Didn't know about temper, so the first one is probably going to crack, but we'll see!

Awesome, thanks

nice one - all 3 are interessting to me. I worked with wood and oil, beekeeping and sealed my plaster chess figures with wax and crafted with pine resin. And personally i love all 3 (smell and taste). you could just dunk them in oil or wax and heat them over time (like allmost cooking them). easier to process for large quanteties and they can absorb it better. but wax becomes water permeable above 37°C (see waterreduction by honey) and is mixable with oil (may not ideal for hot or oily consumables). line seed oil on the other hand needs to cure for a long time (heating may cause cracks?!), may try it after 2 or 3 weeks again. And oil should expand while oxidation and may close gabs better. pine resin was my bet as best performens, but it is harder to get in large charches and more complicated to process. your brick ciln or a bbq could help to reduce the resin down to a thin layer. Also, isn't there a technik by mixing resin with charcoal (like 1:1) to seal woven buskets? but overall nice experiment, thx

Good ideas, thanks. I think a long term job of sealing with oil would be better, soaking in oil for a day or two, then slowly drying. But really that is too time consuming, I would prefer a quick coating on wax or pitch, even if I need to reseal them from time to time.

Greatest video thank you for this information knowledge😊

I love the "no, I dont have a control, because I'm NOT a scientist" especially because you do have theories and are testing and documenting most of what you're doing. Yeah sure, its not rigorous and exhaustive, but you're experimenting and documenting, which I would call the heart of science.

Its nice to see you two....doing something like this......its awesome

I really enjoy your videos. Thanks for taking the time out to show your viewers. I tried to gather clay and it went horrible wrong. I know where I made my mistake . The process went well except for the material I used. I loaded the video on my channel. It is titled Making Clay Disaster. I've learned to really make sure you harvest clay deposits.

I'm sure you will do better next time. Treat your mistake as a learning experience and keep going.

I am a scientist and, since we all know what happens if you don't seal your work (hence the fact that we use a sealant in the first place), I think your experiment is good. Not all experiments need controls. It's ideal but sometimes it either isn't possible and/or it isn't ethical. In this case, anyone who wants a control can try to use their pottery without sealing it.

Dropping the control means you lose the math, something to be avoided in most cases. An unsealed comparison lets you calculate how effective each material was off the baseline. Without the control, we do not know if the worst seal had any effect at all. Baseline controls...always. Rigid controls...only if you plan on making it a process.

Hi Andy. Great video again and perfect timing with the content. After I had coffee in my just fired cup it felt kinda damp and sticky on the outside, now I will definitely seal it. Thank you for going through the trouble and sharing this informative video. Looking forward to the next one. 😊 Say hi to your wife it was great meeting her.

Flaxseed is the one of the three that is not only edible, but good for you. In the long run, that might be worth the extra time wiping off residue and drying in the sun (maybe a long dry time and not multiple coats is all that is required?). Earthen floors (dirt floors) are sealed with linseed over a long period of time, then you can mop them. Anyway, it's very cool how they all worked.

Hey Andy! I recently got interested in ollas as a concept and tried some experiments at home using my backyard clay. Your results match a lot of things I noticed as well. I wanted to see if I could adjust the seepage to a level that was more acceptable so a puddle wasn’t left under my pots, but still allow seepage to have optimal evaporative cooling of the liquid inside. So I tried combinations of beeswax and animal fat. Surprisingly the lard seemed to not help too much, unless I melted it and put it in the pot so it could seep deep into the pot. the beeswax definitely worked really well, I used it to seal the bottom of the pot and that helped prevent the puddle as well, because the bottom doesn’t allow any airflow so that water could not evaporate and would instantly puddle. But I left the rest unsealed and that seemed to work the best. But I was thinking maybe having 1 coat of linseed oil could help it to slow down the seepage just a little, because I was still getting a ever so small puddle at the bottom P.S. I asked chatgpt to give ideas for partial sealants as well. It suggested applying wood ash or bone ash as a glaze during the firing process

interesting test, I have my own supply of beeswax so thats what I would use but intriguing to see the flax oil and pine resin along side. Thanks for sharing

Another wonderful video!! I very much enjoy your content Andy 😊

The association of smells is learned. When I lived in MX for a while, I had to learn that the strange smell of the laundry and dish soaps, would eventually be associated with clean, but at first, it did not!

I have visited Mexico many times and totally understand that about the smell of Mexican cleaning products.

Just want to say I love your channel. I've been wanting to get more experience in the old world ways and you boosted my interest in clay from like 5% to 100. One thing I do choose over your dry method is wet "sifting" .Just imo, it gives you the chance to wake up any bacteria, and easily get rid of them, their wastes, and past bioorganic debris. Of course there's always bacteria in clay, but this has been getting me a nice consistency, as compared to other clays I've bought, decent amount of silt, and I can control the temper with the sand I took from the base dirt. Just my backyard starting experience from past knowledge and watching your channel 👍.

What a wonderful channel to find.

Thanks for a very interesting video. I was surprised that the linseed oil (aka Flaxseed oil) wasn't more effective. When I purchased my carbon steel wok the manufacturer recommended flaxseed oil to seal the steel. I've also used it on cast iron with great success - liberally coat the vessel then heat it to the smoke point and when it cools it is sealed very well. I kind of expected that stoneware would be the same. So, it was very interesting to see it wasn't as effective.

I saw those cup going upside down on the sand and I thought oh oh. Use a flat stone Andy!

Andy, I love these videos. It really would be a great advantage to have a control in these experiments, though. I for one am very curious how a completely unsealed mug would have held the coffee here. Would it be slightly damp on the outside? A mess all over the table? Would be interesting to know how crucial sealing is.
