Made from a small LPG bottle and a homemade burner with a 0.6mm LPG jet that is actually a 0.6 mig welder tip.

not getting it hot enough, it should be near as liquid as water, and I think the flux (borax) or other impurities has capped it off as well

dave How Ya going . I've seen Phil's furnice in action It gets HOT enough . Something did go wrong with that one though .
Me and Macka did a pour the other year 78 grams in the electric furnace ( that Mother humper gets HOT ) But didn't not get the mold ( Scull) Hot enough & Oh Bugga .
Yep Gold was like Water flowed nicely out of the crucible straight into the warmish mold.
Well " BEEEP Me" Thermal Shock Sucks IT FLOW back out like a Volcano **** spread out over about a metre on the concrete. Not saying I didn't but a few raisins my have popped out.
Got about 76g out of the concrete.
Quick note Always makes sure your Mold is HOT!!!!!
