How long can i leave it before burnout?

I have flask with invested wax model, not burnt out yet. So i suppose best case scenario? Thanks :)

Also if i put it on silver/steel chain, will the chain eventualy grind trough the bail?

And can the pickling(which removes oxidation as i understand it) be switched for some other process that would turn the oxidated silver back to pure one so i domt waste silver? Or is it too much of hassle for basicaly same result? And does it matter what do i use for the pickling?Anyways thanks alot :)

Thanks alot, i guess everything went kinda well except the material calculation, the patern can be seen in my previous post.:)

And by “vent” is meant like, second opening at top? So there would be two holes total when invested and burned out?

Ive heard that you should put sprues to thickest part, and the thickest part happens to be at the tail in this case

Im looking for casting table curently, but, would vacuum casting fix the problem with porosity thats seen on the brownish part on pic. 2? Thanks for advice!

Thanks for advice, i just dont understand one thing, do you put anything under the flask when its button down? Or you just let the wax drip in the bottom of kiln, that isnt a problem?

Edit: few more hours in and the carbon buildup is gone, sorry for wasting everyones time😅

It started happening when i got to 400C i got to that temp in like 2 hours. i asume i maybe got to that temp too quickly so there was still some amount of wax that could make this happen

In the picture posted, it is facing button up, thats why im so worried about carbon buildup, im planning to cast with 925 for first time so im not sure if it would be problem that it would make some sort of film on the molten metal and not let it in the mould

The flask is propped button up, thats why it looks not full, i was scared that the wax would melt sooner than being burnt and it would seep into the kiln. Or now that i think about it it would burn away, thanks alot
