Melting Rocks and Rock Glaze Experiments
HTML-код
- Опубликовано: 14 окт 2024
- I start with gravel in my backyard, find which type of rock melts in my kiln, and attempt to make a small test glaze from that rock. Since I was at it, I also tested a granite rock dust I had on hand in a similar way.
One of the fun aspects of owning a kiln is to do experiments like this. I would do these things anyway, but making a quick video for your pleasure makes it twice as fun. Please leave me a comment. I do like comments.
I hope you enjoy. Please subscribe.

Great idea to melt rocks. I've tried scoria, pumice, and lava, since they were once liquid at not very high temps. Mostly I melt dirt, though. Depending on firing temperatures, the dirt in my yard goes from a shiny chocolate brown color to a light yellow transparent glass. I've glazed many a mug with it.
Speaking of ash, just a couple hours ago I mixed some fine white elm ash into some dirt from the back yard. Will fire tomorrow morning.
Although it has been three years since your post, I am very curious about your techniques. What are the results of your experimentation on natural stones like lava? Is there an place, where you showcase your pottery? Many greetings
I just found your channel and I'm enjoying your experiments. Since granite is mostly silica and some alumina, you're going to need quite a bit more heat or a strong flux to get it to melt. You could try adding some borax to it. The brown stone however, does show some promise. A ball mill is a great idea to get enough quantity of the powder to make some glaze. I look forward to more of your experiments!
I enjoy watching your experiments, especially knowing that you are saving me time from performing the same types of experiments just to see what happens. Great job! Cheers :)
Awesome! Thank you for doing this!
I love that texture from the granite.
This is the kind of content I'm looking for.
Very interesting. John Britt did some articles and videos on roadside glazes. Here in Australia, Ivan Englund made a series of glazes from various quarries. He had the rock dust analyzed and then did Seger formula calculations to balance the various elements of the glaze. The results were extremely beautiful, glossy and restrained glazes.
Best summary I've seen!
Thank you, I’ve just come across lots of stone dust ( mainly granite, I think) with these two experiments you’ve already answered some of the questions I had going on in my head 👍
thanks for sharing the results. great content.
I would like to know more about this process, kilns and techniques, fascinating, info gladly received.
The red rock is most likely agate with a hardness of 6 - 7. Glass is 5 - 6. So very similar. Love the experiments !!
Great video thank you
you should melt some aventurine glass stone or gold stone on pottery or something... it is glass with copper in it and the copper cristalizes and makes it glimmery. there must be a way to make it into a glaze somehow
I love the red rock!! That granite would be awesome for the outside of planter pots.
thats amazing, ur a ceramic master.
is that red stone potassium? does your glaze burn?
The green rock on darker green looks like olivine in basalt
I find them all the time. Ancient India they were able to mold that into different shapes for temples.
And I want to try that with some of the ones I have and others. I rock hound all the time and am planning to test some geological theory's. Going to be a while before I have all the stuff to do it. But will be making a video of it.
My channel is going to be all about making different kinds of things and going way outside the box so to speak on my own thoughts of how things come about!!😁
I hope everything turns out good.
Very nice experiment kind sir and thank you for sharing.
Ooh a stone sword. Casting a stone sword!!!!!!
Love your experiments. Fascinating stuff! :)
Rock dust is the key to all ancient building
well interesting . cool video
Can you tell me what's the name of the chemicals or the brand name please🙏🙏
That granite finish is sweet and shows real potential (IMHO). The red stone is very nice. Both would be interesting to see after they've been ball milled. There's a video about a British potter who incorporates washed beach gravel into the surface of his pots before firing, comes up with beautiful results on the naturalistic side. Tried to find it for you, but to no avail. Here's another interesting project you might consider: DIY ball mill :)
Is it bonded or stuck?
Justin I've just found your channel and may have missed it, but what temperature are you firing up to?
I think you're on to something really good job bro
The black one was obsidian. Can't tell till you crack them open because of weathering
This is awesome
Thank you!
How hot was it?
He said cone 5 I think. That would be 2050 F.
Try citric acid with the granite, maybe let it sit before applying, would be very interested to see results!
the brownish-red stone would make an interesting speckle ingredient
The granite might be okay if you pasted it on in a certain way, like what people do with slip.
first game ever, where you win for being weak.
Why didn't you just crush them and run the dust through the strainer?
how much temperature in Celsius?
What you're saying is this is nothing but sand and you made some black glass and congratulations 😁👍😊😁
Wat acid u use
How hot did you fire these experiments?
Cone 5, so about 2,100 F.
The rock that melted was clay that hardened into rock basically like a common opal, thats why it melted so easily
what was your firing temperature.
In the video he said cone 5 so that's 2050 F.
I'm pretty sure the rock that melted is an igneous rock called rhyolite . Supposedly at least 60% silica
You should get something to refine the dust down a lot more
Interesting.
I wonder what melted jade would look like
Abone oldum, doğal bir sır yapman güzel daha çok deney gösterirseniz, bilgimiz artar
👍
Wait. What’s a kiln?
3000° plus to turn granite into lava ( obsidian )
Did you try a smaller mesh?
I did not. I just have the 80 mesh. I think a ball mill would also be a good choice.
So that's how they built the pyramids, pumping liquid rock, they used plants to melt it tho. 😁
Brave to use wet rocks. You'd be lucky if they don't blow up.
Z-clear representation that ancient Inca and Aztec walls may have been as easily as painted on there is something to this video there's some science hear people need to understand further more tests must be done much more critical testing must be done maybe that's the key rock dust
1260c should give u better tesults
What if that's how they built the pyramids
Dude....a hammer and some concrete would have been way faster...easier and funner to make dust
In your title of vid is melting not cutting
Dude have you ever heard of a rock crusher go to ask Jeff on you tube
Use lava rock
