Thanks for posting. I have a project to do and this really will help.
Brilliant, great to see the different results
Thanks
Great tutorial, many thanks x
Interesting and informative video, useful information.
Thanks, very informative, and I love that your not mixing powder into the resin.
Silly question, what brand/model is your scale and where are they sold? Can’t find it anywhere.
Fantastic!
I am so pleased I did this video, it seems to be very popular which is great. Don't forget to like the video and subscribe to the channel
Try using a small soft paintbrush to brush on the powder inside the mold, that works too :)
Great tip! but i do find that brushing can remove as much as it puts on.
@@NicoProps i did find that out with some of my peices aswell sorry
Interesting!
Well done. From Cyprus
thanks
Hi, if your mold was a seamless one and you had to use a release agent, would you have sprayed it right before sprinkling the powder? Thanks!
i'm not sure that would work as the spray would potentially make the powder clump, if you are using a silicone mould you should be able to cast just about anything in it without the need of a release agent. mould release sprays are really just used to extend the life of the mould that being said the only exception to that would be if you were casting silicone in a silicone mould which you would need a release agent for. another thought is that even if the powder didn't clump you are likely to get a texture on the surface of the casting where the release is and the casting medium can not get to. long answer short preferably you would not use a release agent.
Been wanting to try cold casting for some time now. Think I'll give it a go after seeing this. Thanks for the step by step. One question tho... in your experience do the metallic powders (regardless of brand) eventually flake or rub or chip off easy? Fairly durable?
so far they have been fairly robust but there is only a thin layer so if you think the piece is going to get knocked or scuffed you could could give it a couple of coats of clear coat to protect it.
if you polished a master to a high shine, up to 3000 or 5000 grit, and then cast in the polycraft black, would you get a similarly glossy casting or would the shine be lost? thinking about combining it with a silver pigment powder + buffing for a polished aluminum/chrome-esque look
you could do that but because the powder is just a coating on the mold you would rub it off and leave the black resin but yes you could sand it with high grit paper then use something like t cut to polish it to a shiny finish. if you wanted to have it polished and still have the metal effect you would need to do old school cold casting with actual metal powders mixed in with the resin
Would you recommend brushing the powder in the mold?, or would it work best if you shake it inside?
I would say shaking in would be the best option, the brush may not give it an even coating and it may remove more than it puts on. also you will have lost a lot of the powder in the brush.
this is a great video. are those mica pigments?
yes they are basically
I like the idea of using pigment powders instead of actual metal, but can they get wet without washing off?
yes they can because they are embedded in the resin. if you do have some concerns you can always hit them with a layer of clear coat
hello sir, are those powder from ebay prone to scratch easily? any tips on how to make it more durable from scratch rather than clear spray coat.
all the powders are prone to scratching off i would recomend a good clear coat sealer, just a clear car laquer would work well.
Would this apply to casting a hard polyurethane rubber too?
yes it would, however the powders are likely to rub off over time
The cast magic is only about 6 bucks CAD at sculpture supply canada how's it so much?
I'm in the UK and all Smooth On products cost a lot due to the costs of importing
I can't imagine doing this and not finishing them with steel wool or something of the like, you might as well use basic opaque colors in that case.
you would do that with cold casting actual metal powders but with this if you buffed it with wire wool you would take the colour off and painting them would remove detail.
The ebay link doesn't seem to work. Was Intrested in trying them
just search killer blitz it should bring them up
@@NicoProps thank you
So these don't polish up like cold casting with metal powders?
No you don't have to polish them up like you would with bronze, or other, powders. in fact if you did you would rub it off them. you can hit them with some clear coat to protect the coating
Hope you have subscribed and like the video ;-)
Does it only work on black?
depends on the clour you are casting but black is the best base for most metal colours
NicoProps thank you
Hey nico great video ,if you have some time, jump by my channel and say hey.... keep up the good work... 😁
Thanks, I did pop past your channel and subscribed I have done some Aluminium casting a few times I haven't tried Lost foam casting yet as I have not always been pleased with the level of clean up required. I may give it a try to see for my self, I've been meaning to build a new furnace ;-)
Hi, just reaching out with a view for a possible future collaboration, I am going to be taking up bladesmithing and at some point, once I have had enough practice, I would like to make a few swords and was thinking I could cast parts in bronze. Might be an ideal opportunity to collaborate on a few videos. I have bought an ingot of bronze ready for when i want to try it out.
You miss the most important part! Since the smooth-on product is real metal, those pieces can be polished to a metallic luster. I can't believe you didn't take some steel wool and a polishing pad to these.
if you do then you take the coating off, its not the same as old school cold casting, you only have a very thin layer
@@NicoProps Ah. I'm doing some research on cold casting for a project, that's why i mention it. You could do a powder/resin mix and brush it into the mold before you pour. I would have loved to see a comparison after a light polish.
@@andrewhedman1271 cool you will have to share the results, yeah you can brush up the mold with a mix of resin and metal powder then you can backfill it and polish the surface with wire wool. you can also put the metal in your pour instead and skip that step.,
