Just popped over from Robs channel, glad I did. A very well made video, none of us should underestimate the time patience and effort that goes into getting it right. Thumbs up from Suffolk UK.

Thanks for the shout out. Heating the mold will definitely give a better outer surface result, as will letting it air cool. Water cooling can cause serious localised shrinkage. Those little bubbles are from hydrogen gassing. You can virtually eliminate this by pouring the ally as soon as it's melted. It and the dross should never glow red hot. The hotter it gets, the more it will gas, so as soon as it's runny do the pour. Overall it was a good result for a first attempt. You're doing some excellent videos. Next time I touch on this subject I will give you a return shout out and help get those numbers up. Cheers Rob.
Thanks a lot Rob. Yes, I did probably cook it longer than I should have. There was a lot going on for the first attempt, but I should be more organised next time. I now have some ingots so I will have more control over when I can do the pouring.
I wonder if the issue was what ever the tin was lined with? The aluminum seems to have stuck as if it was welded to the tin. You can see in some places where I removed the ingots that it has ripped aluminum away from the ingot and it is still stuck to the steel. I will sneak the tray back into the drawer so the wife can make some cupcakes:)
Molten alloy dissolves steel [tart tins] you need to coat them with a refractory wash,I use a zircon based refractory wash on my ingot molds & pyrometer probes & dross skimmers also if I occasionly us a steel crucible I coat the inside as well,hope this helps
Xyudu, ROB sent me,new subscriber looking forward to the videos.
Thanks for watching Kentucky Trapper. There will be many more videos coming.

I'm here because of Rob's recommendation :) Howzit from South Africa. Thanks for the content!

Howdy from Montana, USA. Just swung over from Rob's channel. you have some good content here, I think I'll stick around for more! Thank you!
Thanks Kyle. There will be a lot more videos on all sorts of different things coming.
Landed here from Rob's channel. G'day from Tasmania (North Island of Antarctica).
Thanks from stopping by.
Good work. I did leave some of the tips I read about on your previous video. Hopefully they are helpful.
Thanks Ben, I will take a look.
Rob sent me, and I'm glad he did!
Thanks for watching.
JP, the texturing at the bottom of the good cupcake mould might be your answer.

@@thehobbymachinistnz I think Mrs JP might notice. Oh......and don't eat any more cupcakes made from that tin.

Thanks for the information and your suggestions headstocktailstock.
ali prob too hot when casting so fused it to the muffin tray
Hi, thanks for watching. You are probably right. It takes ages to melt cans and all that aluminum was in the furnace for a long time.
