So I started at about 10:30 am. I placed my ceramic shell into the kiln leaving the vents open and turned on one burner to low. Just to ensure no moisture was in the shell. For the next hour, I re-tooled my shank to be adjustable and some other minor fiddling. At 11:30 I tossed the crucible and bronze into the kiln alongside the shell and turned the kiln up to high-high on the two elements, starting temp was 0,130c. Note Outdoor temp Temp 87F Dew 73F Humidity63 % It rained at the 2-3 o'clock hours in full sun the whole time, very odd weather. At 5:00pm kiln temps were at 1,128c. Outdooors: Temp 85F Dew72F Humidity65 % I set up my pouring area, ran all the steps in my mind checking to make sure all tools were nearby. check setup turn off kiln open kiln remove shell move crucible to the plinth clean off the surface of the bronze attach shank pour Any overages in ingots release shank move crucible to the kiln for slow cool. Step 6, cleaning off the surface of the bronze, took longer than expected and step 7, attaching to the shank, I ran into severe problems. I had testing the shank in a different orientation for the initial test and the crucible was 180* in the other direction for the actual pour. The result was 1/4 of an inch too low, I had to raise the locking mechanism on the shank, which I started to do and realized that I was taking to long, I returned the crucible to the kiln while I got it right. I had turned the kiln back on, but I did not give it the hours needed to get back up to full temperature, before trying to pour again. When I came back to pour it was no longer runny but thick. Moving to pour it plopped a thimble size piece of bronze into the shell, it fell like lava instead of running like metal. I knew immediately, 'this is wrong' I returned the shell and crucible to the kiln, setting it to high for 2 hours. 7:15pm Outside: Temp 87 F Dew 73F Humidity 63 % Kiln: 1,143c I then redid the 11 steps to complete the pour. I waited for the duration of time it took to say a rosary with my family, and then quenched and broke the shell. There was a larger high silica brown oxidized clump of error on the center of the piece. The shell absorbed the "plop" and it did fuse to the piece as "extra" material. I plan on grinding it away in the metal chasing processes. De-sprue'ing resulted in a strange geode center in the center as a bubble inside the piece and the sprue below the pouring cup. I am a little baffled. It did not affect the face of the piece. The piece has defects past my basic blunders, small sub-grain sized holes, possibly air from slurry I can keep this piece and hopefully make something respectably elegant with a lot of chasing. Current weight of piece: 4.8lbs (bathroom scale) Lessons learned: I probably need 2 kilns or under the advice of 'everyone': a fuel foundry and a kiln. This just reinforces all that, which I am working towards. Don't doddle, I could have saved a minute or more of time and not had the pouring problem. Shell absorbs bronze over long times in higher than melting heats (I suspected this) If this plop pour happens again; Master Jason say put the shell upside down. One corner was imperfect. The corner sprue needs to touch the back side of the corner and be trimmed square. More sprues on edges as well need to be added. I had a lot more minor defects in the casting. I want a higher bronze temperature overall next time, blow off the first layer of air bubbles when dipping the slurry, which I just brushed before. There was a geode in the main sprue off the cup. I need to post pictures and ask questions, temperature? I really have no clue what to chase metal with. Ask questions about tools: What power tools can I use to buff and clean in the metal chasing that I can get at ChinaFreight? I was told ss wire brush, maybe mine are ss? What is with this geode?
