Ahaha, that's definitely a fun way to interpret the photo. No, it's a dark grey plastic. Some sand has remained stuck to it at the back, but less...
Just tried putting a batch in an old bread kneading implement - well, really it's an old Kenwood multipurpose kitchen machine affair, but this...
Denis; one word there jumped at me: "mulled". Now, I've not been mulling my sand - I've figured between all ramming it and breaking it up, it...
Oldironfarmer, yes, yes I was. The photo is admittedly a little poor demo of it, but I've tried many different quantities from "just a light...
Okay. Preliminary results are in. More clay definitely has the potential to help. Did a lot of blind testing with little 100 gram samples of sand...
Hmm.... I wonder if I could be low on clay content. Because that's the behaviour you'd expect with too little clay, no? Little binding strength,...

For talc, something olfoundryman said in one of his videos I think. As for starting this thread - it is obvious that the pattern pullout isn't...
Yep - 1/5mm layers are what and FDM printer typically spits out, and that truly is grabby. That's what V1.0 of this pattern was like, haha. I...

I've done it this way too for the very first attempts. I flipped it around so I could feed the metal in from the bottom and provide better venting...
A good bit of time sitting outside with sandpaper and a tiny little metal spatula of sorts that could get right in there. SLA resin sands like a...
Looking at how olfoundryman uses parting powder, I think I am now picking up that he does in fact want it on the pattern - just in moderation,...
Alright, alright! By popular demand, some photos attached :D 1oz silver maple for scale - it really is a wee little one. But it does have fairly...
On the pattern itself, I'm using nothing. Otherwise I'm using just some calcium carbonate which seems to have the effect of gluing one layer of...
