Lisa, I once had a batch of a clear glossy glaze made from a recipe in Mastering Cone 6 Glazes that had sat for a couple of years and formed hard pea sized nodules on the bottom of the container but still melted to a glossy glaze. My suspicion is that in storage the temperature fluctuated from the 90's F to the 40's F which caused something to dissolve and then crystallize out as something different. I tried heating the nodules with a propane torch and they did not melt but did turn hard. I also found that they would break down in vinegar but not plain water. By crushing it appeared that there was a seed particle in the middle and the nodule had grown around it. Fun chemistry stuff.
@@urlkrueger oh how interesting! After I did all the work I realized I probably should have run them through a sieve, which I do after I batch them but not usually again. I didn’t notice any clumps or hard particles though. I add 2% bentonite to all my glazes for suspension so maybe that helped prevent clumps. I wonder what ever created that nodule you found?? The chemistry is wild for sure!
great job, as im in a studio setting all glazes are made up or brought in, only playing we have done is with glazing it putting one glaze on top of or underneath, so we are starting to build up a visual reference of how one glaze works with another or what just doesnt work, but it was interesting to know, everything seems ok. i have heard to get lids off, dunk the container lid first into warm/ hot water for a few seconds and then it should undo, if i find out more info i will let you know. Thanks for doing the hard work, next time i want to know something and i google it, will it say Lisa Riland says "do this" lol. another informative video Lisa thanks
Oh boy you maybe give me too much credit :) but I'm happy I can help hopefully. I've been in the studios too and only had options of what was there and creating your own combinations for different effects. You can still really make incredible pieces and the advantage is often the studio owners have found good stable glazes that are typically successful which is really helpful. I did actually try soaking my lids for a few min before and it's a game changer! so so so much easier than what I was doing and less painful on my hands.
So interesting, wish I had the interest in making my own glazes. That purple is gorgeous! I was noticing that ‘pig’, salt pig on the shelf, that’d be a neat tutorial😉
Thank you! Yes making your own glazes certainly isn’t for everyone, it can quickly consume all of your time. Fortunately we always have commercial glazes 😊. I will have to put a salt pig tutorial on my list of videos to make, thanks for the idea!
I love your videos. I’ve now binge watched them all. You’re one impressive lady!!! I’d love to learn about you. What’s your backstory? How do you know so much about wood working/cabinet making? Were you a professional potter/how come you stopped for four years? And where are you from? :-) I’m a relatively new potter and am obsessed with everything pottery.
Oh my goodness thank you so so much, that is the biggest compliment!! I am not a professional potter, just been a hobby for 30 years, I took about 4 years away as I was learning to build cabinets because I wanted some custom cabinets for our new house and it was 2020 and with the materials and labor shortages I just figured I’d do it myself. Learned everything woodworking from TH-cam! I’m in the US, in northern Colorado. Where are you from? I’m super excited for you getting started in pottery, it’s just the best and endless amounts of things to try, test and learn. So glad you’re enjoying the videos, I’m enjoying making them :)

This is such a great video and so much information for everyone. You are such a chemist too!
You are amazing! I’m a beginning potter and have been learning so much from your videos…keep ‘em coming!!!!!!
Oh thank you so much!!! I’m so happy you have found the craft and my channel too! Thanks for watching!
I would love to try that process! Your dragonfly is gorgeous!
Thank you!! She is a bit tedious but then result is worth it 😊
You are amazingly smart. I love lessoning to you. I’ve learned so much from you! Thank you
I'm so glad! Thank you so much, I wouldnt say I’m super smart 😜 but I do love this stuff so so much and sharing it has been such a blast!
There is a standard cup with a standard hole where you time the number of seconds it takes to drain to measure viscosity diresctly
I believe it is called a Zahn cup, correct? I’ve never played with one but have heard of them.
A very technical issue made easy to understand, thank you!
You are more than welcome I am so glad it was helpful for you!

Great video !! Thank you
Thanks Jeanne!! Glad you liked it!
Good video,thanks
You are more than welcome! Thanks for the feedback, glad you enjoyed it 😊

Lid removal hack… Immerse the container upside down in water for a few seconds say 3 to 5 seconds take it back out and Walla it opens😃
Oh my gosh this will save my hands and wrists so much! Glazing today and will 100% be trying this. THANK YOU!!
I tried this just the other day, worked perfectly thank you again!!!!!
