Friends, this is a very old video, and my technique sucked, for actual GOOD green sand casting technique see this video: ua-cam.com/video/CCBsAKCMTME/v-deo.html It's much more recent and has lots of good advice.

Great video but I have a question that how long can we keep on using that burner or torch?I mean can we keep on igniting it for hours or do we need to give it a rest?it is dangerous to keep it on ignition for hours because it could get too hot or can we use it for as long as we want?

Hi there. Good question 🤔. I suspect it varies depending on what the type it is... I made this ramshackle burner so I'm not sure on its limits... close observation 👌

@@FloweringElbow thanks.I am a little worried about that.

[@hotheadsniper]

Can we use flour to dust it?

[@FloweringElbow]

It is possible but it would burn.
