I did my ceramics master’s thesis on using glass as ceramic decoration. The trick is to double fire. The pot needs to be fired like normal. Then the fired pot needs to be fired to about 1350 F slow firing with slow cooling (annealing). I would be glad to share my thesis with anyone.
I've watched videos for crystal glazes where a catch basin was used and after firing, a torch was used on a wheel to heat the joint where the crystal glaze adhered to the basin. When you hear a ping, tap with a hammer. That might help with these experiments.
I really love that you do all of this experimenting! I’m so sorry you have done so much damage to your kiln though. The wood base is absolutely beautiful as well as an amazing idea!!
That chestnut foot was a stroke of genius. It complemented the vase perfectly! Edit: Also love the red and turquoise one; would look stunning with a few tulips put into it
I’ve started fooling around using glass with ceramics. What you could try is mix frit with ceramic glaze. The glass particles will melt at around 1480F. I would use coarse grade frit rather than the fine or powdery frit.
Very interesting Idea. I will try it with coloured glass - say the bottom of a coloured bottle. It would also be interesting to take a pottery piece that has been glaze fired then re-fire it to the full fuse temperature which is around 1475F. There could be a point at which the glass flower but not off the pot.
Use a curved file to score where you want the glass to break at the bottom of the piece. You may have to alternate using hot and cold water poured on the line, and I don't know how the ceramic will react. A grinding or polishing tip in a Dremel tool will help to smooth any roughness.
What if you crushed the glass into really fine powder in a ball mill or something, and made a liquid glaze out of it? You could do it with different colored glass, and just paint it on, or dip it?
I will be mixing a little frit (powdered glass) into a ceramic glaze fired to cone 10. I think what will happen is the glass particles will melt resulting in a streaky effect.
what about sanding the sacrificial glass to a matte finish so a glaze has an easier time sticking to it and totally painting it before using it like this
How fast are you firing these and to what cone? If you do a firing one day and are able to do another the next day I’m just wondering because my kiln takes a long time to cool so I can’t do firings on back to back days. Thanks.
Why aren’t you using zyp in the bowls or cups to better facilitate the bits coming out clean? Also if you have your heart set on sling it your way, I’d recommend making a base that has long thin tripod legs. That will help make the pieces come apart more easily.
Just been strolling through some of your videos ,it's very cool ,if you have time to answer ,do you make replicas of those old XXX moonshine jugs , or dose anyone use amfori for storing wine anymore
If you get a glass grinder (wet grinder) you'd be able to grind a hole into the bottom of the jars before fusing to let out any trapped air. You can find them in shops that sell stained glass supplies.
no amount of coats of primo primer / boron nitride / kiln shelf wash prevents sticking at glaze firing temperatures (2200+F). I've done this a few times trying to "sneak a slump" on my glaze firing. Its' frustrating but if you want to unstick your glass, its meant for 1550F ish max.

Hi, I’d love to give it a read!
I'd love to read as well!
PLEASE SHARE
I'd love to read!!
I'd love to read your information.
I am just loving these expertements - thank you so much for sharing ❤

Beautiful! I love the wooden base. Your experiments are so much fun to watch! Thanks!
Wonderful experiments.....me thinks you are having too much fun testing on the edge of possible disaster.
Thanks for sharing Justin!
Nice - I love your experiments.
I really love that you do all of this experimenting! I’m so sorry you have done so much damage to your kiln though.
The wood base is absolutely beautiful as well as an amazing idea!!
Amazing, thank you for sharing
This is a really beautiful technique. The light blue and dark blue are the best. Success!
I just love this channel :)

Beautiful!!!
Fantástico!!! Felicitaciones maestro 👏 saludos desde Argentina !!

Fascinating!
I really enjoyed this video. Make me feel so uncomfortable until I saw the results. Great job
Mi piace anche questo connubio ceramica/ vetro: bravissimo!!!!!

What cone and time were used?
How fast are you firing these and to what cone? If you do a firing one day and are able to do another the next day I’m just wondering because my kiln takes a long time to cool so I can’t do firings on back to back days. Thanks.

Oh costly experiment
Have you ever tried using antique cobalt blue bottles?
Do you have any of your glazes published anywhere?
at what cone did you fire these to or did i miss that?
Different color glass gives what kind of look?
Have you tried a smaller piece of glass?
❤️❤️❤️❤️❤️
Please try to melt pulverized glass, with with different grain sizes. :)
Cool as usual. How many kilns have you burned through?
Hah! Only one small kiln before this one. I just keep replacing the bricks and elements as needed.
@@JustinsMakery I just got my first kiln so I am babying it. About to load my first glaze fire. Eek!

Justin -- what are the 2 little rod shaped items standing in the kiln to the right of the pots at around 2:18? Is that kiln furniture?
Good eye! I have another video coming up where I make large ceramic pulleys. Those are the pivot pins. :)
Crush the glass and mix with glaze
What's the firing temp /cone no.
Cone 5

You know you can drill a hole in glass?
If you use batt wash on your bisque containers the glass shouldn’t stick.
