I've definitely walked by homes with tons of rocks like those in their landscaping and thought 'It would be cool to create all the rock forms and then glaze them and have a ceramic 'rock' garden landscaping feature like that'. Now I know that I don't have to make the rock forms :)
I’d say that blue one cracked during cooling if the crack looks “fresh” and not filled in with glaze. It still could have been slightly cracked from falling and then just showed up after firing and cooling. Cool video. I love your intrigue and creativity. I would never have thought to glaze river rocks.
Ha love your experiments! would never have thought to do that! Those rocks are mostly silica so its not that surprising the glaze didn't run. There would be lots of potential to absorb/ neutralize the fluxing agents in the glaze. The fitment is more amazing though, i definitely wouldn't have called that!
You likely could have just used the hot glue, as the resist, and glued it to the prop instead of the dowel. It would have saved a step or two. I guess it shouldn't be surprising the rock survived. It looked to be granite, which is one of the main rocks, that clay is formed from. I also know of a potter, who incorporates crushed granite into his thrown work. In regards to possible applications, a person could do underglaze painting on rocks, with a transparent glaze on top. It would be more durable than using latex/ acrylic, especially outside.
I suspect that you could have glued the stick to the rock and then added the wax, as the hot glue would have resisted the glaze too. I also wondered if you have a set of glazing tongs and could have dispensed with the sticks altogether. Anyway, great experiment! Keep the 🔥🔥🔥 going.
Have you ever used one of those round webber bbqs as a kiln? Love the rocks, the bottom of the pink one got darker also. Thank you for the fun and mayhem. Cheers!
It would be interesting to do a porosity test on the rocks after they came out of the bisque kiln. I’m guessing it’s going to be somewhere around 1% or less. They’ve got to be as close to vitreous as you can get. I’ve had some success preheating unglazed pots in order to achieve a thicker glaze application. Steam comes flying off. Very cool experiment. Thanks for posting.
Hey Justin what was the white cylinders that you were propping it up for for kiln furniture? Really interested in those stone firing was pretty cool to when I thought that might try it as well raku firing in the ground with some of the other low fire glazes like lusters end it might be easier to brush on the glaze than to drip it depending on the clothes you have look forward to hearing from you
You could wax the bisque holders you put the rocks on in the glaze fire, set them in a bowl, put the rocks on and pour the glaze on the rocks, let dry, wipe the residual glaze from the bisque towers and fire the rocks on them as you did.
I think that the bisque wasn't needed after all. It was more to make sure they wouldn't blow up. I'd still be nervous that I'd grab an unlucky rock and put my kiln out of commission.
I think bisque firing is cheap insurance because many rock can still harbor moisture in them even when they appear totally dry. Great experiment. It answered a fleeting thought I had once, but I didn't follow up.
Justins Makery I just watched a video by Matthew Kelly and he mentioned you. You made a stamp for him. I thought it was really nice since I also follow him on TH-cam.👋👍
Warm the rocks first, then use glazing tongs or brush on glaze in coats. Or put warm rock in shallow pan and pour glaze over it up to waxed area, waxed side on the bottom. Or glaze the whole rock, let it dry, and sponge off the bottom. Duh.

Did anybody else jump like they were shot when the rock dropped LOL?
It's cool to see you like to go outside the box with your experiments. It never crossed my mind to try this. Thanks for taking us there!
I friggin jumped hard when that rock fell! I really like your videos. Keep experimenting !

Nathan Spevack that’s an a awesome idea! I haven’t seen that
I feel guilty for laughing so hard when the first rock fell 😂
Oh my gosh, you are amazing!...also loved the climactic slo mo replay

I like the look of the unglazed rock fired to the higher temperature. It would be nice to have some pots like that.

There would be lots of potential to absorb/ neutralize the fluxing agents in the glaze. The fitment is more amazing though, i definitely wouldn't have called that!
I had been wondering about this. Thanks for trying it out.
Love your adventures! I bet you were a hot mess in a high school physics class!
Also thinking they could make some cool mushroom sculptures if you glazed that foot to them, maybe adding dots of black glaze?
Ohhhhh....mushrooms! That's a fun idea. Going on the list...
Thanks for the bit of fun, you never know what you'll come up with!

How fun! You’re the Bill Nye the Science Guy of pottery!

i feel like a jerk, but i laughed out loud when that rock fell in the glaze. i actually wasnt expecting it.

awesome!
Awesome splash very much like something I would do
Thanks for the wild imagination!
Cool!

Good thing the rock fell into the cup....saved the counter top.?
2or3 coats better than one ?
Thanks for sharing this fun experiment......
Those smooth rocks are cool and all... How would the glaze respond to a broken piece or a super rough surface?
Maybe brushing glaze on would be a lot easier? Nice job
Hi... You could apply the wax after gluing the rod to the rock...
Shop vac would work to hold the rock when dipping
What type of glaze did you use? what temperature did you fire it at? And for how long?
You could wax the bisque holders you put the rocks on in the glaze fire, set them in a bowl, put the rocks on and pour the glaze on the rocks, let dry, wipe the residual glaze from the bisque towers and fire the rocks on them as you did.
That's a solid suggestion. I ended up pouring over the top of them anyway. Thanks!
Do you make or can shelf stands be made? Thanks.
What are brushs for
Open em, could be dragon eggs ;)
It's raining skittles.. 😋
😲
great way to sign your art, just put fingerprint into glaze pattern
Justin, What would happen if you didn’t bisque fire first?
I think that the bisque wasn't needed after all. It was more to make sure they wouldn't blow up. I'd still be nervous that I'd grab an unlucky rock and put my kiln out of commission.
Justins Makery oh! I didn’t think of that. It completely makes sense. Thank you so much for your kind reply. I enjoy watching all your experiments!

5:22. You jumped. I laughed. Nice replay.
How about a hole in the rock and forcing a threaded rod for the glazing.
Concrete drill bit are inexpensive and could do the trick
Warm the rocks first, then use glazing tongs or brush on glaze in coats. Or put warm rock in shallow pan and pour glaze over it up to waxed area, waxed side on the bottom. Or glaze the whole rock, let it dry, and sponge off the bottom. Duh.
Not sure why someone would want to glaze a rock!
What is this
its like a acrylic paints,,,
I'm edified
It looks like you painted them with Acrylic paint lol.
This way no crack no.explosion
I laughed.
Make mm's
Oh dude that sucks LOL
