  1. Sculpting and casting

    Whoo! Thanks for the luck The cast was a success! The picture below is what it looked like after I removed the investment with citric acid. This tree were cast in silver, so those white specs that you see is actually fine silver and the gray stuff is oxidation- this is normal, I use 925 sterling silver which has 92.5% of fine silver and the rest is copper. The copper in the silver reacts with oxygen and what you'll get is that dark surface, which needs to be removed before polishing. That's what I'm doing now. Lots and lots of sanding, sawing and filing. Here's a few of those hands after the first rough sanding. Had no dents or holes, which is really nice: Back to work, cya! ~Julia

    Jack, Thanks. I'm hopeful, that someday someone would like to have a whole set...*fingers crossed* emmagine, thank you so much for the info- I'll definitely test both Fimo and Primo. Every now and then I get these commissions that reach my workshop just way-too-late. For a caster this is a nightmare, because I only have enough time to make a single cast, that has to be perfect. It feels like taking a swim in the middle of the night...and knowing that there are sharks. You'll most likely be just fine, but the idea that something can go very wrong lingers inside your mind like some kind of superglue. I'm commissioned to make 20 hand shaped logos, that has a spiral in the center and spirals are nasty things to cast! Here's the master: The tree that I whipped together today and is going to be cast on wednesday: Wish me luck ~Julia

    Today was more of a traditional work day. My workshop looks like a war zone. I made a silver brooch for a customer using 1mm silver wire and a whole lot of soldering and polishing. The pin wire is stainless steel, so it will keep it shape better than silver. Don't know how many times I lost the miniature hinge...dropped it a few times, lost it in the chaos among the tools and before soldering, found it wrapped to my clothes

    Thank you. I'll make a master straight out of the wax model- I want to be sure to have at least one plan B, if the cast comes out incomplete spending a few bucks on mold material is a way better option than having to start all over again. That's why I love RTV-silicone, being able to make a mold from the wax model or any other material, that would be destroyed in vulcanizing temperatures. But the wax will be cast in bronze, after the mold is complete. I want to see how the blue carving wax burns and does it need a longer burnout than the injection wax. I've heard that the hard green and purple waxes needs to be at the highest temperature at least an hour extra to have a clean cast. This was the first time I used the blue carving wax. It's quite nice to work with, especially now when I've started to understand more of what kind of tools I like to use as it's so much different than working with soft waxes. That ring is mostly done with burs, wax files and an exacto-blade that I modified to have only just the tip for carving very small, tight places...cut only just one finger, so I'm evolving Oh and the wax can be polished with turpentine, which is nice.

    Kang, ravens are beautiful creatures...from a distance terrifyingly big birds. We run out of gas for melting, so I still have time to make a few new tests for the next cast. I'm in a hurry, so I'll have to keep my ramblings short Carved my first celtic knot! It still needs to be polished and cleaned up, but I'm pretty happy how it looks right now. Got to run, cya!

    Hey! Andy, it sure does save a LOT of batteries- it does help if you clean the tip with a brass brush once in a while, the wax tends to build up and burn, making the burner less effective. The wood burner sounds interesting, just thinking that will it be too hot for wax? If there's smoke, it means that the wax is burning and that changes the wax structure somehow. What I've gathered from the casts gone bad, it may be a reason for porous bits along the sprue channels. I've had it happen to me once, but there are so many things that can go wrong, that it's difficult to say what caused it. Wang, wow..googled the wax pen, never realized it shares a name with a vaporizer. Oops, heh. What I used before was a Matt speedy wax pen, it's great when fixing and melting small bits of wax, but when it comes to building a tree, it takes ages to get everything attached. So, $29 is just about the right amount, plus taxes and shipping. DIY is the best Mori, it's nice to meet you too! Did you happen to finish the elf yet? Eagerly waiting to see it painted! Strawhat, thank you! I kind of locked myself into the workshop for couple of days; had a maddening phase of procrastination. It's driving me insane to get stuck on everything I try to accomplish; my head is as useless as trying to catch farts So at the moment, it's pretty much a big no-no to read the forums before I get to work. Oh well, this usually doesn't last more than a week (hopefully): can't wait to be able to function again! But thanks to the lockup, I did manage to make a new model of a raven. The model has a bird on both sides and I'm thinking that I'll make yet another spoon collection...or a really fancy fork... or a hair pin? Well, something usable anyway. I'm going to try the medallion idea next, just to see what it looks like after it's cast.

    Popping in to say hi. I've been making wax models to assemble at least 4 big trees for both silver and bronze casts. A vital tool for me has been a wax pen, that I use for melting wax for various purposes. I'm so used to it, that losing an equipment like that feels like being without power and that's what happened yesterday; it stopped working. I panicked, because buying a new one (even while being cheap) is not an option at the moment. So, after a frantic search around the house to find something similar, I came across an old glue gun. I modified it. There's now a thin silver wire at the end to conduct heat, held firmly in place by a bit of green stuff I now own one of the world's cheapest wax pens ever made. It cost me around 6€. Behold! The DIY wax pen. It's darn ugly, but it works:

    Thanks might make more squids later: perfect for left-over green stuff. Cleaned up a bronze cast that I made a while back- never done a scythe or any weapon/tool of this size. Was on my "things to try"-list. Just like the dragon this will be made to be part of a spoon, plus a few to be made as pendants. This is a master for a mold, so as much as I'd like to tidy and clean it more, it needs to have as much material as possible for future casts. I'll solder a sprue to it later today.

    Had a training day for sculpting. Have a bit more control now: tested a mix of super sculpey firm and green stuff 50/50...not a bad mix, adds some working time and is not as sticky as green stuff alone, plus the color is quite pleasant grayish green. Might work well with the jewerly modelling, it takes twice the time to cure tho'. My end result is kinda weird, chubby and cranky squid

    Oh yes- anything organic (or even plastic) will do, as long as it burns and the ash is blown out with compressed air before pouring- it's a good idea to add some wax underneath a flower pedal or anything that's under 0.5mm to have a better chance to have a good quality cast. If the item is big, it needs to be dry or dried before casting- otherwise it might blow up inside the investment during burnout. Organics are usually one time casts, though and due to ash it's better to use an own tree for those items or you may risk to lose hours of work. There are a lot of hobbyists and a few artisans here that does that kind of work, it's fun, but expensive as you'll rarely get a full tree. Another option for sort of organic cast is to use a cuttlefish shell. This can be done with a really small setup and work as a one-time mold. But it's best to do outside as the fumes smell otherworldly disgusting and will remain as a good companion for a long time

    I do like this raven idea. One might be better than having two at the same design, it looks too busy and crowded now, with one it could be shaped as a crescent moon...I'll choose that later.

    Sure thing There are three types of molds, that I mainly use. First is the two part liquid silicon, that I use for detailed work and with material that can't tolerate high temperatures. It's semi-transparent, which is nice..but difficult when taking pictures, doesn't look like much. I'll be making one soon from the milk can, so can share the process. Second mold is vulcanized. This is good for making molds out of items that are metal of any type. This is a mold of the rabbit- I cut the mold just enough to get the master model out. And third is an instamold- it's silicone (I think), quite soft. I found it at a crafts store real cheap- you add it into boiling water, press the item you want to duplicate into the mass and let it cool and you'll have a mold to do simple models with a soft wax or putty. It can also be used again.

    Ouch, good thing that the cuts are usually clean and heal quickly. I hate the ones you'll get from a leaf saw, like paper cut with a twist: it gathers all the silver dust in the world. Living in a small town is great. For instance, no one can hear you scream. Literally, no one can hear you- now that the winter is almost on our doorstep, the average age around the town is about 60+. If I curse, when a tiny bit of green stuff acts like a removable pimple, the people outside most likely think it's a stray cat. Yes, I did have some trouble with the green. It had a temper tantrum day and I'm still too newbie to handle such acts. Well, here's an anatomy pic of the milk can: Sawed it in two and made a base, where I'll attach the sprue channel later. There's also a thin slice of green stuff in the handle (the reason of cursing) that I added to fill the gap inside, so that it will be easier to remove from the mold and can be cut out before I cast. Also, I made sure that there are no sharp turns anywhere. I decided to keep the bird theme on my next sculpting project, but the eagle has to wait- the painting is still too freshly fleshed into my memory, that I don't want to see my reference for a while. So I had an idea of using Odin's ravens, Huginn and Muninn to make sort of a medallion type pendant. The other half will be cast in bronze and the other in silver. Roughly sketched what I have in mind. I'll make a more detailed drawing later, when I have the time for it: ~Julia

    There's always a way, just have to find it. One technique is called the spiral cut, where you sort of cut a spring into a mold to help to release the wax model...I tried it once, but also had a brainfart of the month: I balanced the mold on my thigh as I cut away the rubber mold. Were lucky to wear thick jeans- fresh blade cuts real nicely both mold and everything that happens to be underneath when the blade decides to slip. Felt like a winner. I'll surely try it again, but next time will fasten it to somewhere else than my leg Attached the handles to the churn and green stuffed the lid to have a nice, smooth surface. Going to post pictures later, bit under the weather today- hopefully I'll get more work done tomorrow.

    Hi, I love my work. Can't say that enough I'm working with a commission, that were given by a local company. They are manufacturing cheese...I do hope to get a sample of their products, when this is done- perks of the trade! What they are asking is an old fashioned milk churn, that could be used as a pendant or to store small items in, so it will have to have a working lid. The items are going to be cast in both silver and bronze: 5 silver churns to be given for their employees and x-number to be made to their store. I'm excited, because this is something I'd never even thought of making myself. People are great with their ideas! What I've done so far: I made a rough shape of the churn by using 50/50 mix of both normal super-sculpey and the firm ss. I like the mix, but I have to say that it was kind of an accident find. The normal has always been just a little too soft for my liking and the grey stuff that I have is good for small detail on it's own, but it's way past its life cycle, and just kind of crumbles...so my panic-side took over and mixed stuff together and behold, it works! The shape were done by wrapping the clay around an old micron-pen. What I don't have is an oven to cure the clay, so I cure these by placing the objects into boiling water- it does make the material a bit brittle, so just have to be a little careful when handling these. Next step is to make the small handles and start to refine everything with green stuff. When making casts and especially when I know I'll be making a mold later, it's good to keep the thickness around 1mm to ensure that the objects fill completely- the model will be hollow, so once I get everything sculpt, I need to harden the surface with epoxy and saw it in half...so there's still that moment of horror ahead. Oh, and I'm designing a new model of an eagle. I finished a painting for a client last week and I still have quite fresh image of the whole bird anatomy thing, so going to use it for my advantage. And I still have the line drawing, too Here's the bird painting: See you later, ~Julia
