Thank you for teaching us about wood ash and glaze composition. And for the recipe. Your a good teacher. I have learned a lot.
@ muditsallabout - hi there, I tried it and it works in electric kiln as well, you can apply the glaze on greenware and bisqueware as well; my kiln fires only up to 1220C (cone 6), I used unwashed ash and I did get a nice result, a little on the mat side but not running; I guess if your kiln can reach higher temps you can get it more shiny, cheers, gabor
Thanks Simon, great info. Your an inspiration.
Hey Simon, added bonus to the video - your hat is strobing! lol!
Wow!what a good demonstration, n straight pointed. Thanks, point well taken
You live in PA too?! Fantastic! You're such a big inspiration to me. I made my first piece in a bonfire last week from dug clay. There is such an amazing world to explore with this medium, clay & pottery. Thank you for helping guide others who would like to go from the ground up.
I'm so glad I watched this video. I love the natural glazes and woodash look. I now know I need a gas kiln!! Shopping now!
There are electric Kilns that reached cone 10. Without a problem.
Thanks! It helped a lot 🏺
Learned so much
Great! Just got a $8 aspirator on the way. For cone 5 firings I may add a little Gerstley borate to the ash suspension to see what comes of it. If it's a mess, it was still fun and interesting.
Great commentary! If your practical wisdom and perspective are accurately represented in this video, I'll be watching the lower half of your face often! What sort of sealing properties does wood ash offer?
Hi Simon!
I'm using natural, clay brought in from Dél-Dunántúl(South-Transdanubia) in Hungary. It's very low fire clay compared to the stoneware you use - I fire at around 985C right now (cone 07-06, I think), and for so far in an electric kiln -
However!
We're moving out to a farm next month, and there's some decent looking clay not too far from the surface. This is on the Dél-Alföld, Southern Hungarian Great Plains. I know this stuff's been used circa 50 years ago still, so I'm thinking of going through the whole sifting process, which I've done some studying of, so that's not worrying me too much as of yet. It is yellowish, so Iron-oxide's in it, and it isn't flameproof - traditionally in use for jugs and bowls. Can be used to cook on coals, and in a stone oven, if done with care.
The part that's more bothersome is that I'm not satisfied with having these complex fritt glazes brought in from faraway lands, so I was wondering weather you might have a guess at being able to produce a glaze that is low fire (max. cone 05), and waterproof, and not reliant on import. I am building a woodfire kiln out there and chucking the electric one once I'm settled in enough. I never really wished to use the electric anyway, I just didn't have the circumstances.
Is this Ash glaze any good? So far I've only found material about it being used on stoneware.
Thanks ahead for the reply!

Did you have any luck doing it on low fire?
I'd love to see how that slag works when ground to a powder, maybe mixed with ash or local clay.
Have you seen the recipes for Cone 6 woodash glazes? If so, do you have any thoughts about them? There were some in Ceramics Monthly last fall.
I've always been of the bandanna mind when it comes to 'large' particles (larger than fumes). Wet bandanna if I'm really worried.
Could one add some whiting to the ash and make a white glaze? I've seen fired egg shells used as whiting, just wondering if it would work?
I like simple glazes!
Hi Simon, i tried your nuka glaze over your celadon glaze and it fired to a lovely turquoise colour, the same over my homemade tenmoku?? strange.
If you press against the side of the sieve with a vibrating massage wand, it will quickly be sorted. This method is widely used in industry to process materials in a rapid manner.

so dildos are a valuable potters tool? TIL
If it can vibrate the sieve; absolutely.
mind blown
Hi Simon, You gave your recipe for the ash glaze as 1/3 ash, 1/3 custer feldspar and 1/3 flint. Is this by weight or by volume? Thanks -
always weight
Can i glaze earthware clay with ash glaze
What's the name of the green glaze at 13 minutes into the video? Do you have a recipe for it? I supposed to be going to my first wood firing soon and I'm trying to get ready. I'm super excited!
its a celadon glaze good at cone 9-10.
SIMON LEACH POTTERY TV - raw glazing & impressing march -2017 check out this recipe and then add 2% red synthetic iron oxide for the celadon
thats a video title btw !
Hey Simon!
I recently learned that "rule of thumb" is derived from the laws (England, America, Araby?) that say that a husband can beat his wife with a switch if it is no thicker than his thumb! How terrible...I like your use so much better. Thank you for this wonderful video.
Should've been the rule of wrist, can do much with a thumb width...
Can the ash glaze be fired at 1100C max?
Hi Simon, quick question - is the wood ash glaze food-safe, or does it need a clear glaze over top of it?
Yes it is food safe at cone 10, I do not know about other temps , but I would say yes in general it is.
Simon Leach I'm still learning, aiming toward primitive skills. I dug the clay from my own field and the ash is from the fire place. Also dug a 3 ft deep pit in our clay soil that will have a clay oven type of set up on top of it... contains all the fire and heat, adjustable small vents, etc. Think rocket stove or pizza oven. Still trying to figure out the "cone" temperatures as far as how they work in just a wood fire. No one says how long to burn in the fire, or how many times to fire it, just basics. I just want to make some dishes or pots or something for my kitchen from my property, something simple for now to learn. Then I might make Christmas gifts.
I don't have any square buckets, but I have some round ones. I haven't found any slag in any of them.
Hi Simon,
Can you use wood ash glaze on Earthenware?
All the best,
Benjamin
You can indeed. Make sure you sieve it at a rather high mesh though, as thick wood ash melts at high temps.
Ok - Thank you.
Can you fire in an electric kiln?
11 Regent Street Yep! Wood ash seems to like higher temperatures though. Simon fires to cone 10-11 if I'm not mistaken. But of course, there's low fire recipes as well. I'm experimenting with a cone 04 wood ash glaze myself.
@@connorcaproon451I'd love to see if that recipe worked out for you I've been looking for stuff like this recently
Manny from Black Books :P
Simon: Is the wood ash (alkaline) glaze FOOD SAFE?
Yes food safe !
...at cone 10 anyway.
Much appreciated! Thank You, Simon!
Thanks!
They wash the ash because it removes the sodium hydroxide, which is a caustic... idk if it is food safe after being fired, but I'd like to know.
Around 13:50 for how to apply.
what if you dont hsve a place that you can get the ash then what ????
I am now in Millheim PA16854
2 words, air compressor(and atomizer kit)
Whoa whoa whoa, Pennsylvania where?
+Breton Lynn cause I'm in Bucks County A.K.A. pottery/tile mecca of the U.S.A.
I live now in Millheim PA 16854
wow you're right in the middle of PA aren't you. Have you been to Bucks County to see the Mercer Museum or the Moravian tileworks? Lots of awesome pottery, totally worth the trip
shit the house i just moved out of had that slag everywhere!!
Don't get that dust in your coffee. That will taste yucky. lol
What's in the cup?
Vodka?
Sounds like you're pissed LOL
Are you thinking good 🤓❤❤🤓🤓🤓🤓🤓🤓🤓🤓🤓🤓🤓🤓🤓❤🤓🤓🤓🤓🤓🤓🤓
Interesting topic but what a poor presentation, painful to get through.
