If you put the flow control valve at the tank instead of at the kiln you can stand up and several feet away from the kiln to make adjustments. :-) I adjust mine from a lawn chair with a good cup of coffee. Also means I don’t have to wear a respiratory very much if at all.
I certainly hope you both have a pressure regulator between you're hose & burner and the propane, butane or LP-Gas tank. It is extremely dangerous to not have a pressure regulator. Why? If the tank runs out of gas the fire can back-feed itself from the burner through the hose and explode the near empty tank when a vacuum is reached from temperature change.
Thank you so much for this very comprehensive and informative video; and it is so professionally presented too. I intend to try this technique very soon.
Nice work and beautiful pottery. Here are some tips. Try decorating some using Liquid Salts and Acidic's such as Iodine, Asian Soy Sauce, Raw Lemon or Lime Juice, Sea Water and or Ash & Water mixed with Purple Dye or any colored dye or mixed dyes for that matter.
Try opening the burner port all the way and using the knob on the propane cylinder to adjust gas flow. On my setup I’m able to make smaller adjustments to flow without having to get close to the kiln
I very much appreciate you sharing your techniques and the effects possible with them, and as much as I dislike when others go full safety nanny, there's a few bits to point out that will keep you and others safe when doing these things. The least scary part: ceramic fiber blankets are made with a high degree of silica which will absolutely go airborne under duress of elevated temperatures. While I applaud your use of the respirator and goggles, unsealed kaolin is still "dangerous" even as it sits with normal exposure in handling and firing; the more you're exposed, the greater the chances accumulate of developing silicosis (basically a build-up of silica bits on and in your lungs). Sealing kaolin fiber with sodium silicate liquid is a very cost effective and safe method to keep it locked in place. You can make it if you like, buy the powder and mix it yourself (with ppe equipment, naturally) or purchase pre-mixed solution, but I normally go with the powder and add water for convenience. Now with the relatively small amounts involved with your pottery, chances are relatively small you'll have a problem, but I'm very timid when iron and aluminum particles come into intimate contact in any substantial quantity. I've dealt with powders of both and done purposefully, so if gases given off during combustion or elevated temperatures of firing are possible, that you might have to read up on. Point of the matter: aluminum and iron _powders_ react rather excitedly (read thermal violence) when exposed to high heat in the form of thermite, a chemical reaction that burns at temperatures upwards of 3300*C/6000*F and is for all intents and purposes, impossible to extinguish with consumer-level equipment. When done purposefully, it's often used to weld railway rails together and takes a significant amount to heat to initiate, but once it touches off, you stand back and let it go while whatever around it goes up in a shower of sparks and copious smoke. I'm not saying stop everything you're doing that involve the two materials. As said, in the amounts you're dealing with there's a relatively slim chance you'll encounter problems, but it is something to consider for the one time the unexpected happens and your kiln turns into an unquenchable volcano.
Wow! Thank you so much for sharing this coveted process. Question for ya, it sounds like you are firing at approximately Cone 015. Do you know how higher firing temperatures affect the Saggar process? I fell in love with Cone 10 firing at Uni but that's like double the heat of what you're working on here. Seriously cool beans. Have an amazing day!
Great video, very nicely done. Could you share a little more about how long you take to get to the target temperature and any temperature steps and hold times that you use?
Hi Jonathan, thanks for your comment. I put a bit more info about temperatures and schedules in this article which you may find helpful...thepotterywheel.com/saggar-firing/
no, they are low fire pots and not water tight. Because they have been bisqued, they are ceramic, but the finish is not water tight like a pottery glaze.
Hi. Beautiful! Congrats! I have a doubt... Is the terra sigilatta essencial to the process? I have a lot that far already been "biscuited", but it's porous. Will this effect work on it's surface? Thanks again for sharing.
Hi Lucas, you don't have to use terra sig, I don't always use it. But it does give it a smoother finish, and it polishes up nicely. But no, you don't have to use it. Good luck. Let me know how it goes :)
Thanks for a great video. Have you tried lacquer/varnish rather than wax? I've started using a spray lacquer, you can use matt, satin or glossy. This way the pot is better protected and easier for your customers to care for the pot.
Thank you vert much for this great video. Could you please list the ingrédients you use as I Couldn’t understand as my english is bad. Many Thanks in advance. All the best. Ludovic
Miracle-Gro isn’t pure copper sulphate. I’m just checking if this is correct? Miracle-Gro contains urea, urea phosphate, potassium chloride, boric acid, ammonium phosphate, manganese EDTA and iron EDTA. Is this what we use?
Good day! I love your content, very precise in the processes and materials, thank you for giving us your knowledge. Could you tell me how I find in the miracle glow industry? What's his name? Well, thank you! Beautiful work ❣️🇦🇷
Hi Simon. The aluminum gets very thin, papery and brittle and it just falls away from the pots. I'm not sure what temperature it would become molten, but the kiln is hot enough so that it becomes very thin and fragile.

your videos are excellent and my students are learning a lot from them. but what is a sargar? everyone everywhere calls it Sag - ger as in rhyming with bag. Terra sigilatta has a soft G, not a hard g. it's not a country thing with pronunciation because everywhere calls it terra sij (more like a J sound for it)
Hi Linda, I'm glad your students are finding the videos helpful. I think my pronunciation must be a country thing. It's just how we pronounce it around here! It's not just me, honest!
I thought it might have been pronounced that way, as "sigillata" means "bearing sigils" or decorated with designs. But I couldn't find a pronunciation guide. :D
The wax you use at the end is a skin irritant - does this mean that when the pots are polished it's still an issue to hold them? Thanks for this amazing process video, btw!

Hello! I am amazed at your video. I love doing raku but I was unaware of this technique. I don't know what terrecigolata is, some kind of wax? I couldn't find it on Google, haha. Is there a formula to do it? Thank you so much!!!!
On the topic of turning off the burner, you should always kill the flame at the furthermost point from the source, reason is what we learned in school, is that when the escape velocity of gas is greater then the velocity of combustion, we have a safe environment where most likely nothing wrong can happen. BUT as you turn the wheel to shut down the flame from the bottle itself and NOT at the nozzle, there you have a recipe for disaster, there is still gas inside the tube from the bottle to the nozzle, the escape velocity of gas can now be lower then the velocity of combustion and you can have a little poof in the tube, now if you are at the end of life of bottle there might be lower pressure inside the bottle itself, and the whole thing can explode in your face. ALWAYS TURN OFF THE GAS FROM THE NOZZLE NO MATTER WHAT !! The pressure inside the hose is a layer of safety :)
If you put the flow control valve at the tank instead of at the kiln you can stand up and several feet away from the kiln to make adjustments. :-) I adjust mine from a lawn chair with a good cup of coffee. Also means I don’t have to wear a respiratory very much if at all.

What kind of clay did you use? And was the Bisque fire to cone 015?
Hi Anne, I use scarva earthstone extra smooth ES10 and bisque fire to cone 06
Hi great video can I ask what clay body you use thanks
I use Scarva earthstone extra smooth :)

The right name is TERRA SIGILLATA
She also mentioned she has a link in the description on how to make it
Is your burner a weed burner?
yes, just a weed burner

ALWAYS TURN OFF THE GAS FROM THE NOZZLE NO MATTER WHAT !!
The pressure inside the hose is a layer of safety :)
Thanks, that's helpful
Hermoso!!! Could you please tell me what’s the name of the first chemical you used please?
If you mean the liquid, it's ferric chloride
I'd suspect that a degree in chemistry would be of immense help. But at least a voice of much experience.
Beautiful!
