Copper Casting - Making copper "Trivets" for the kitchen

Рет қаралды 41,275

Күн бұрын

In this video, I make a set of solid copper trivets in my home foundry. I made pattern using fusion 360 and the 3d printed the patterns in a plastic called PLA. Then I made a sand mold with a sand called petrobond.

As some of you have pointed out, copper isn't the best choice for trivets. I like the look of copper and thought these would look interesting looking regardless of whether they work as well as they should or not. Also, we have granite countertops so heat transfer to the countertops is a non issue. I'm still going to make some feet for them though. Thank you all for watching! 🍻

@drucker03 7 ай бұрын

Little pieces of felt glued under the feet will be sufficient. So you avoid scratches, too.

@clubley2 Жыл бұрын

I guess they have a large thermal mass so this may not be an issue, but being a conductor of heat is the opposite of what you want from a trivit. It's supposed to isolate the surface from heat to protect from damage. I would replace or cover the feet with rubber.

I've seen some king of random videos. Your right I believe he did a lot of open mold foam casts. I do mostly closed mold foam casts. For copper you would need a thicker shell. Copper is too heavy and would bleed out into the sand.

@Critters Жыл бұрын

Copper will suck the heat out of your pan/meal. And transfer the heat quickly to the surface you are trying to prevent heat getting transferred too. It'd be cool to add some rubber feet (those little sticky dots) to protect the surface you use it on. And maybe CNC/Laser cut out a thin piece of cork sheet to adhere to the top to make it as functional as it is beautiful. You could pocket out some shapes on the top surface to inlay with cork or do a trace of the entire shape, anything to prevent direct contact of the pan with the copper.

@nixie2462 Жыл бұрын

Drilling some holes and putting titanium pins as heat break would also do the trick too.

@robinson-foundry Жыл бұрын

That's not a bad idea! I figured copper wasn't the best choice but people enjoy seeing copper casting. We have granite countertops so the only real heat transfer will be from the hot pan to the copper trivets.

Uhm, isn't the point of a trivet to keep a pot/pan's heat isolated from a (table) surface, both to keep the pot/pan hot, and protect the surface? Wouldn't making them from the _very_ heat-conductive copper be somewhat counter-productive to that point?

@corneliushuber2716 Жыл бұрын

Im not sure copper is the right material for this since it is very conductive. If you want to use it anyways the trivit probably isolates better if you keep the feet on the upside to minimize the amount of heat transferred from the kettle into the trivit and spread the heat your desk will have to deal with onto a bigger surface.

If you want to eliminate the shrinkage dips in the t sections of your casting you can "chill" those areas by placing steel blocks on those areas when moulding. When the liquid metal hits the chilled faces it will freeze of and stop the shrinkage.

isn't solid copper the opposite of what you want for a trivet? you want something that is super fibrous like pressed paper fibers. Basically, you want asbestos pressed into that shape you've made. Obviously you don't literally want to use asbestos, but you want something with all the same properties (minus the whole cancer thing). Buck Knives sells a recycled pressed fiber cutting board that works great for this, and it has a nice knife that slides into the bottom
