Product Description
Oyumaru Instant Mold is a fabulous reusable instant moulding material. Use it to make a mould, change it into another mould, and another mould... and so on! Re-use it over and over.
This great Japanese silicone non-stick moulding material is re-usable, so you can keep using and reusing it to make lots of different mould shapes. Perfect if you need to make lots of moulds but only need a few copies cast from each mould. It is a heat softened and reusable putty that once shaped cools and hardens instantly, and does not stick to Art Clay, PMC, polymer clay, Green Stuff, Kneadatite, Stick Putty and other common sculpting putties. This product is sometimes referred to as Instant Mold.
Oyumaru Instant Mold picks up fine detail surprisingly well. It is excellent for fingerprints. For our gamers and model makers; use it for casting replacements or making your own extra bits like: weapons, shoulder pads, armor designs, bone swords, lash whips, fairy wings, army models, nids, wargaming & faery making. You can combine several sticks to make larger moulds.
To use:
- Just put the Oyumaru block in hot water for a few minutes, and it will be soft and ready to be shaped.
- If you change your mind and want a new mould, just re-heat in water and start again! No shelf life. Can be heated and moulded over and over.
- Don't put this on your hotplate or in a dehydrator to dry your metal clay - your mould will soften and lose its shape. Only air-dry until the metal clay is dry enough to pop out of the mould.
MEASUREMENTS: Each stick is around 6cm long.
PACK SIZE: A box of 7
Also sold in a bulk 24 pack!
Please Note: This material is not food grade.

OMG!!!!
Wow! This is the best mold kit i've ever bought! I use it with Alumilite Amazing Clear Cast Resin and it is sooooooo perfect!!! <3<3<3

Amazing Value!
WOW! I've tried many molding compounds over the years and have just a little play with this. A really good impression of my own feeble fingerprint first time! I can't comment on long term use but initially, WOW! Great value!
-
Brilliant!
Really good value. I like that you can reuse it...in other words, if it's not quite right, you can do it again. I'm new to metal clay so thought this would be perfect for learning to mould stuff, before I bought something that can't be changed if you mess it up. Super easy to use! Love the smell of them too! I got in the instructions translated and they say "pick it out with chopsticks" which made me giggle!

I was sceptical...
However, good result with ease.

I'm Amazed!
I was very sceptical when I bought this due to the low price and the claims concerning how good it was, but I was really amazed at the results....so quick and easy! Just had to drop it into hot water and it softened up! Very easy to mould and use, and it hardens up very quickly. Once you no longer need the mould, it can be dropped back into hot water and you can start all over again. With 7 sticks in the pack, this is fantastic value for money.....definitely well worth it!

Oyumaru
It's very nice. It is very easy to use and the result is very good

a bit stiff
excellent for value, but when trying to get the clay piece out of the mold its a bit hard to do without the use of cornflour. also cracks a bit too easily after a few uses, personally prefer mold putty. *****RESPONSE FROM THE METAL CLAY TEAM***** Hi Emma, thna you for your feedback! It sounds like you are using the Oyumaru for polymer clay (as you're using corn flour which you wouldn't do with metal clay)? You can always warm up the mould - very, very, very gently so you don't ruin the mould shape if you want to reuse it - which will make it flexible and easier to remove the clay you've moulded. This product is aimed at people just wanting to do a few copies of an original, it shouldn't be your first choice if you want to make loads of impressions of the same design. For that, any of our silicone based moulding compounds would be better (and they all stay flexible). ***END OF REPLY***

Fab
i read all the reviews here first before using and heated it as suggested - it worked perfectly - would recommend to anyone who wants to make good sturdy molds with a possibility of reusing the material again !
-
easy
amazingly easy. found it works best if you keep the boiling water in a cup rather than tub is packed in as it stays hotter for longer. love that if you mess it up just put it back in the hot water and start again. works great with poly clay. great detail! :) thanx for the super quick delivery!
-
Great stuff!
Really good product. Worked brilliantly, as the other reviewers have described. Take care not to get it stuck to the side of the pan though!

So much fun!
I've no experience of other moulding compounds, so can't say how it might compare. But I've had a lot of fun with the small pack I got to try with base metal clays - it's inexpensive enough to tinker with. One of the things I wanted to do was make some Celtic type knots in leather and make moulds of these for jewellery components in copper and bronze. I haven't fired them yet, but the moulds were crisp, detailed and accurate and the pieces I've done with it look better than I hoped. I've also made some deep texture plates by moulding over shapes I've made in wire - and the results from those are looking good too. Fingers crossed that they fire well - I'm excited to see how they come out. I shall have to buy a bigger pack next time, it's great fun to work with and it easily re-constitutes to use again (and join more than one piece) if you're not happy with the results. I found it worked best to shape the mould in two stages; firstly to knead and shape it to approximately the shape and size of the item you wanted to mould, then re-heat it to make the actual mould - that gave a much crisper result as it cools and solidifies quite quickly. As others have said, it does need to be boiling water to get it soft enough and if you pick it out carefully with a tool, the material itself is actually then cool enough to handle with bare fingers.

Does what it says it will
As I read in previous reviews, works best after soaking in boiling water; tap water isn't hot enough. Delivers excellent results with both resin and clay. Thumbs up!
