I didn’t like how the plates turned out after the first firing, so I have added a bottom layer of white glass and a top layer of powder which includes some transparent oranges, marine blues and sea greens. the white powder is opaque..so I am a little nervous about that and I may have too many layers going on at once, increasing the risk of bubbles or cracking. Letting the kiln work it’s magic!
Painting is about adjusting and readjusting.
Before I do anything else, I must adjust the value planes. The ground planes should come close in value to the sky and each mass of cliffs need to get lighter, cooler, and softer as they it recedes. I also don’t like the regularity of the left side diagonals. They need more variety. Colors are currently muted but will get stronger as I build layers.
I am somewhat disappointed on the way the glass for these plates turned out for several reasons. The blue is not varied as I had planned. The black and “river” is too dark, and most of all the yellows and greens that I had added for subtle contrast disappeared in the firing. So…. some thought and reworking is in order. I will add another decorative layer and re-fire to get a cohesive design.
The 19″ Glass bowls turned out great! The bases for them are ready for the kiln…just needing to make more pieces to fill it.
Below is a 4’x6′ oil painting I started of Yellowstone Falls. (partial view). I blocked in lights and dark using warm versus cool colors. I am a little hesitant sharing the painting at this stage because I have a habit of experimenting to the point of disaster. Hopefully this painting will go smoothly. I’ll keep you posted!
With multiple firings, I created these 19″x1/4″ glass disks. Now I just placed them in the kiln on the molds which I prepared yesterday.
I’ll be heating them slower than normal as they are thick.
(200F/hr to 1180F) ( Hold < 1hr)(Cooling AFAP to 900F) (Hold 3 hr)(50F/hr to 700)
I have a couple of concerns: 1) Because of the sower rate, I might cause devitrification (scummy glass) 2) the edges of the glass disks extend a tiny bit past the edge of the molds. Glass expands more than ceramic, so the edges might catch on the mold.
Prepping Molds for Glass Platters and Plates
I decided to post what’s happening in my art studio in addition to posting photo tips. Many people are interested in what I am doing, even when I bounce from one art medium to another. I decided to let you see my process:
Today, I am prepping ceramic molds used for shaping glass. I coated these molds in a refractory (50% aluminum hydrate and 50% EPK + food coloring) to keep the glass from sticking to the molds. I must pre-fire the molds to about 400 degrees to get all the water out so that water molecules won’t bubble the glass. Tomorrow they will be ready to receive the fused glass.

Nothing enticed me to walk on my two broken feet faster than seeing a grizzly bear outside my patio door! Eight weeks after painful foot surgery, I leaped out of the wheelchair and grabbed the long lens. Luckily the bear was on the other side of the river so I didn’t have to worry about out running him. Temperatures are warm this November in Wyoming, so the grizzly bears are still up foraging for food.
