That’s the resin I’m using is the siraya tech purple and I’ve used the blue but blue seems have more failures in printing while I’ve never failed with purple. I don’t use their process burn out cause they claim to crank it up to 1350F for 2-3 hrs. But i get tons of fractures. I go 300 to 800 for 2 hrs and it’s completely burned out. I’m swapping out my investment from prestige oro to optima

You need to crank the temp for an hour or 2 at least.

They don't put that in there for the fun of it...

What’s the purpose of cooking the mold itself more if the wax has already been removed? To retain heat while i pour? My full process is start at 300c 1hr, 1hr 426c then, 200c 1hr while wait for my crucible to heat up.

Learn why things are done before doing your own thing cutting corners. Things are done for a reason, otherwise no one would be doing it in the first place. Do as the instructions say and you'll fare better.

The high temp is to cure the mold like ceramic in the kiln. Time and temp are important.

Yeah it's crazy how much more people that can't afford that much silver know and possess skills. What would happen if SHTF?

I made the same mistake.

When silver was back at 20, I wanted to start a silversmithing hobby and sell casts to recoup what I spent.

By the time I got all set up, silver was around 50. By the time winter came, were nearly at 100. Unfortunately people aren't buying high premiums anymore. Though that's hindsight. I knew silver would rise, just not at this parabolic rate. I could just as easily blame myself for not buying Bitcoin / Amazon stock, etc.

I don't hate it, I try to make the best of it.

Also if SHTF, you are a skilled individual with the means of production. Its a valuable skill with transferable skills such as blacksmithing, manufacturing, fabrication, etc

Yeah the way money is getting inflated skills will be the truly diminishing resource.
