I mentioned in earlier blogs that I ran into a ‘running of the glazes’ whilst using my favorite glaze combos. During the time of remedying the glaze issue I researched and found another glaze combo that a) allowed me to experience Testing of Tiles, and b) eventually produced an effect that is so juicy!
I had to lighten the photos a bit to help show the remarkable effects.
I used Amaco’s Potter’s Choice Glazes. Typically I first glazed 2x Obsidian Celadon, then 2x Merlot, then splashes of 2x Seaweed.
First attempt to use brush-on glazes! To become familiar with the glazes, their combos, the running, as well as the processing in the studio kiln, I need to test the glaze on test tiles. So I made some. Well I gave it a try, rolled out some clay, texturized the slab, positioned the slab to dry… but I dried it too long so cutting the slab into little ‘test tiles’ became a chore. Anyhow I saved what I could I bisqued them, and wha-lah! LOL (the studio has an extruder and I was given the green light to use it – yeehaw!… I’ll document that experience in a later post after it happens).
The glazes I’m testing are Amaco’s Potter’s Choice: Ancient Jasper and Blue Rutile. After doing a lil research I LOVED results of using these two glazes that folks were posting.
Sometimes it’s a short walk through muck and mire, and other times not so much – but either way keep ahold of the bigger picture.
These last few months have been attempts to rectify a running glaze issue using the same glaze combo and techniques that I’ve used for years. In this last couple batches I’ve had nice pieces go south. I was getting depressed.
So I’ve had opportunities to tweak:
glaze dip times
amount of glaze
removal of glazes
During this time I didn’t have satisfactory results… as a matter-of-fact the running of the glazes produced another thorn to this potter’s experience because Kiln Shelves were affected, and that’s not a good thing. Especially more so because it was someone else (or a few people) who cleaned the shelves of the running glaze. Knowing the frustration and the hard work to clean glaze off a shelf I surely wasn’t happy to contribute to that.
I also had instances of cracking!
Experienced potters gave me suggestions and I am going to try them all. Here are the tips:
Quick dip of base glaze, in this case perhaps only 2 seconds of the Starry Night Glaze
Almost immediately dip into the Coastal Blue Glaze. I asked about any drying time (thinking of using the time to wipe off the foot) *but the quicker the 2nd dip the better. So to accommodate this suggestion I will try 2 methods
use a tong to hold the piece while I wipe the foot immediately after applying the base glaze, and then drip in Coastal Blue
after wiping the foot and seeing the rim dry enough then dip in Coastal Blue (after finding a dry enough spot to hold the piece)
The 2 options at this point are to use the Cream glaze sparingly or to not use at all.
Potter 2 suggested this after I said I really really like the blue glazing result
Try using “Amber Celadon” as the base glaze and then dip Coastal Blue.
This are my test mugs:
I really hope to find the happy place again, where my Cosmic Blue series can continue. However I am open to new illustrations of the celestial skies using different glaze combos that work well. Stay tuned for the updates!
Researching other Cosmic Blues
I did acquire inspiration after researching a bit.
1) I have to ask my the team at Clayscapes Pottery if I could use some of these glazes in their kiln… Look at those blues!
Pondering, mulling, thinking, analyzing, planning, hoping, etc. Stay with me on this brief venture through exploration & pottery research.
While juggling two clay bodies and exploring my intent for each clay for this year’s creation lots, I ventured down the rabbit hole of researching SLIPS & mason stains in hopes of decorating or enhancing my pieces in a cool new way. During this time my memories included brief mentions from Master Potters Millie (St. John) Schmidt (https://www.ipacny.org/millie-st-john) and Tim See (http://www.timseeceramics.com, https://www.youtube.com/user/timseepots). But I had a twist to include, which was “would mason stains work well on bmix wood clay body for wood-firing“…which I plan to research more of course…
So then I happen to pop over to the issue of CRAZING, which for some reason led my curiosity to body cracking and glaze popping …
Do you see how my mind trails? LOL
So today though, I research and find a resting area in the rabbit hole I’m venturing where I exclaim (silently of course), “Ahhh! My college chem courses have just laughed at me!” (see picture below “Figure 2”). What a good moment for some humor!
Okay, here is the illustration that helped me realize it was time for another cup of coffee:
