Silicone Mold Making Kit - N.W 21.16oz

no bubbles

Good product for mold making. Ok for molding dice if you have a pressure pot, but I'd recommend Smooth-On if you don't have one.

Degassing is recommended

was very easy to use, but only able to make one mold ..... full set f 28 dominoes

I’d recommend buying resin tape to hold down your projects when using this. Also, it tends to rip a bit easy sometimes. Otherwise it works really well and makes usable molds

Good

I used these to make some dnd dice sets and they came out so fresh and clean y'all. There was bubbles but the didnt interfere with my dice. They mostly popped up top. This thing is strong too. Really had to hold it open to pop my dice out. I used the whole bottle and it fit all 7 1.8 m oz cups with plenty of left over so I made more molds real quick. Pour slow and and up at an angle so a fine drip line comes out so it can catch all those details you want. I also saw that if you put you fresh mold in the freeze it slows the hardening process to get more bubbles out. It says wait 12 hrs. I got inpatient and took them out at 7hrs and they came out just fine. I recommend sticking to the 12hrs however. I could just be that I live in Florida and it's been hot and dry lately.This review is not letting my post pics with my review but I am thoroughly happy with the product and will be purchasing again.

Loved how easy it is and better than others I've tried. I overmixed it to make sure but still had a spot that didn't take so had to exacto knife it out.

I was scared I was going to mess it up. Turned out incredibly awesome! Easy to use.. thanks so much! Makes quarantine at home more fun

When it says to mix for five minutes, mix it for five minutes! My first batch didn't set because I didn't mix it long enough. The second batch set beautifully!I use a food scale (I only use it for resins/crafts) for the most accurate measurement and had zero issues. The bubbles rise on their own and it really IS bubble free!Now I can cast whatever I like with this set! It's hard finding small buttons but now I don't have to worry and can make any color I like.

It worked great, I was able to replicate 12 parts using hobby resin and the mold looks like it could make hundreds more.

The product came nicely sealed with no defects. It works wonderfully with my resin and it holds shaped very well. There are a few bubbles, but slow pouring helps with that.

Muy buenoPara .manualidades

Exactly as described. Would buy again.

Wish they sold larger bottles. But good product. No odor. No bubbles. 1 to 1 ratio.

I have not tried any other product s but I am happy with the outcome of this particular silicone. As I am new to this craft I chose this product for the price and it performed as I expected. I would definetely continue to use this product and purchase it again.

Works great

Easy to use . Can add mica pigment for color . ❤️ Feels and looks good.

I got this to make a dice mold to make gummy dice for my players and it set surprisingly quick (about 6 hours for 2 inches thick). This is my first time making molds and this was incredibly user friendly and I personally think it turned out great for my purpose.

I was super excited to get this for Christmas this year, and now that I've actually had a chance to use it I can definitely see some pros and consPros: -Super easy to set up and mix, though I would mix it for just a tad longer than 5 minutes.-Soft when cured, making it easy to de-mold, but just make sure to be gentle especially if you cut them open. I don't exactly know how fragile it can be and I don't want to find out.-Good price for the amount and quality you get!-If you pour the silicon in small cups and let them cure, the end where its the widest will have a surprising amount of suction...this is just a bonus pro for myself, and it's the little things that make my laugh. And I'm adding a picture as proof.Cons: -Its only semi clear, making it especially hard to cut along corners of dice when trying to make molds-It does take time for it to cure, especially if your encapsulating something. I would give it a full 24 hours to cure, though I would say that with a lot of silicon-While it does say bubble free, there will be tiny bubbles present IF you leave it to cure at room temp. A great tip for anyone using at least this silicon is putting your mold in the fridge to cure, at least for the first few hours. I've done three casts so far with two of them being put in the fridge...the one that I had set out was absolutely filled with bubbles. The other two were crystal clear! Also another great tip if you are trying to capture small details is painting on the silicon, that way it can go into the cracks and prevent bubbles forming in them.Overall, I'm happy with my gift, and definitely look forward to getting more!

This is the best Silicone mold material I have used. It was very easy to use. It makes a very durable mold.

I used this to make epoxy molds and it works like a charm

This was my first time using a silicone mold and epoxy plastic to recreate a vintage lawn mower badges....it worked great...I am so pleased. The old lawn mower badges are no longer available.....so my only choice was to make them using my only old badge as a master. I used mold release the first few times...then stopped using mold release....seems mold release is not needed. Great product.

Item came super fast like most things from Amazon do. I was a little scared to use it at first because I had never used any kind of mold maker but it was just as easy as using resin. There were a ton of bubbles and I was worried about that but it seems as though they all came to the top and dissolved properly. I've already used 3 of the molds I made with resin and I am happy with the finished products. The bubbles were from my resin. I was just doing a test pour so I didn't really give my resin time to de-gas. I will buy this product again most definitely.

It greatly exceeded my expectations!

Obsessed with this stuff will purchase again

I almost always use multiple colors of resin in my molds so a translucent mold is a must. I've made small and big molds (1/2" to 4-5") and this has worked great every time. It is sticky to the touch after 12 hours usually on the bottom or sides so I leave it on wax paper and over time, the stickiness disappears. It is easy to use. I would like to see larger bottles.

It takes a little longer to set up than many other silicone products but love that it I almost clear. It works great. I want more. Lots more.

This silicone is much easier to mix than the liquid silicone I've used in the past. That's important to me because I have medical conditions that reduce my hand strength (among other things). It was super easy to mix this 1:1, add a bit of color with acrylic paint, and pour it into my mold boxes. I could see it degassing, releasing the bubbles from mixing, and it ended up with very few bubbles, none of them in places that affect its ability to reproduce the items. It even cured enough to demold the items within just a few hours (I didn't check sooner, so don't know how long it took). I'm likely to buy this again.

It is not recommend to use this cured material with UV resin. UV resin caused rapid deterioration with the cured product. Other than that, performed perfectly.

I use this product to make silicone molds of custom action figure parts, and some of those parts need delicate demolding. This silicone is perfect for a very flexible and easily releasable silicone. I had to let it cure for twice as long as directed however, the silicone seemed to remain very sticky after curing, only on areas exposed to the air. For me it's not an issue, I just hit it with baby powder and you're all good.

This was my first experience with a silicone mold making kit and let me tell you... this stuff is really easy to use and my molds turned out great!

Easy to use, no odor, no bubbles

Literally perfect and easy to color for my own resin molds!!

Love these to.make custom molds

Success! the very first time I tried this. Now I am sure I can get crystal clear results, the possibilities are endless.

It worked well for what we were doing. We cast a set of dice with it and there were minimal bubbles without the use of a pressure pot. The dice came out with the numbers intact aside from some user error.

Works amazingly. Zero bubbles, easy to use and clear so I can tint it. My only complaint and it’s important is that there’s not really enough. Wish they offered something twice this size.

Cures well. Have to use hot craft glue to anchor pieces or they will migrate. Even though the instructions say not for uv resin use, I was able to use it with one of the uv resin brands from Amazon.

Going to start this off with the fact I've never made a mold or even used silicone before this. That said it was a super easy process, the instructions were very clear and it didn't even take very long for the molds to set. Also they came out very clear and crisp, no bubbles, no trouble removing it from the plastic container it had set in, or anything.I ordered this product to make my own D&D dice molds. This particular kit made enough to make 2 molds for 2 full sets of dice plus a smaller mold of misc stuff since I had a bit of extra silicone. I've already made a set to test the molds and am surprised how clean the edges are and how clear the numbers came out.So yeah, overall it's fantastic. Definitely would use it again, and I highly reccomend it. As long as you follow the instructions, should be pretty easy. Just make sure to mix and set the silicone in something plastic so it doesn't stick!

Good stuff worked well

Used this to make molds for resin crafting, I like that it's clear so I can color the molds. A decent price for clear silicone but I run out of it so fast, especially if I am selling molds. I would love a bulk version of this product.P.S. The "specks" in the molds pictured are my fault, it's just mica powder that I didn't mix in long enough, thankfully, they are suspended in the mold and don't affect any castings. Since then I add the mica as I'm mixing the two parts together, mix for 5 minutes (I set a timer to be exact) and pour and I receive the best results.

Good mold making material. mix well and it should be at least 70 degrees or silicon will not set completely in 12 hours. It took 36 hours to set in about 68 degrees. Would buy again. Almost no odor.

This review will be edited time to time for updates!(UPDATE) Still a great silicone product for beginners! I made a second mold and made things in my first mold to compare them to their originals. I will be attaching another photo. Left is originals, right is copies from being in the mold(besides the cookies, I accidentally switched those.) I will upload a pic of my second mold as well! I am going to be switching to another molding product soon as I feel I want a tougher silicone but this was so fun to work with and such an inexpensive option for those who just want to make a few things on hand for back up pieces. My second mold's silicone was mixed more thoroughly than my first and cured much faster. The first mold took about 3 days to not be sticky because I didn't stir very well. make sure if you're using tape on the bottom when pouring and make sure you are taping very FLAT and fold the edges upward around your container because even with hot glue you can get leaks!1st Impressions: LOVE! Very easy to work with, mixes easily and adding a little mica powder for some fun color was NO problem. I only had to wait 3-4 hours to take it out but I'd suggest you wait the entire 24. I think I may have ripped a teeny part on accident pulling it up out of impatience. I am attaching a photo of my mold. I needed extras of pieces I use for personal use. You can never have too many cabochons! I will come back and post pics of pieces made in the mold and update with how the mold did! Sorry the designs are so hard to see in the photo, the mica powder is pearlized.BY THE WAY: I had 1 TEENY bubble and I checked my piece to make sure it wasn't the issue but it may have been because it was slightly not flat in the area it bubbled. Nothing a quick glaze or dome can't fix. The silicone seems strong but I am still waiting to use it as it has only been 12 hours and I want to make sure I don't ruin it. If your mold is still sticky in ANY spots either you did not mix properly or you need to let it cure a LOT more.

This is a very easy silicone mold making set. It's clear so it might be a little difficult to tell if it is mixed completely. But it cuts nicely with zero bubbles.

Easy product to use

Worked perfectly took a bit longer to set but created a solid mold for me to cast from

Was super easy to work with. Was able to demold after 3 hours, but didn’t use for 24. I added mica to give the silicone a cool color

Worked really well. First time user. Easy to use with clear instructions.

I like it,this products are 1st class I am ready to buy more stock from this place

This was a fun product! Extremely simple to use, just measure out part A-and B in equal amounts (I used a small postal scale) and mix together and stir for 5 minutes. Once it was mixed, I poured the mixture into the molds (small Dixie cups cut down to size) over the shells and set them aside overnight. The next morning both molds were solid and flexible. It was easy to pop the shells out and the mold inside was as it should be. I tested the molds using resin with Let’s Resin brand pigment powder and as you can see, the resin is an exact replica of the shells. There was Zero odor from the mixture and the little drip that got onto my work space was easily cleaned with a baby wipe. The instructions were clear and easy to follow, and the packaging was simple but attractive. I highly recommend this mold making kit to anyone who needs an easy way to mold objects. It’s simple enough for a responsible child to use as well. This is my third Let’s Resin product to use, and I have been impressed with all of them. I can see this company becoming a solid reputable supplier of quality resin art products.

It's pretty good silicone comparing it to some of the Smooth-On silicone, and much cheaper than them, I've tried but I ran into an issue of the bubbles not properly degassing, instead getting stuck on some parts of what I was making a mold out of and somewhat messing up the final mold. I did several tests with epoxy and urethane resin to make sure it just wasn't bubbles with epoxy when I discovered the imperfections. Photos show the consistent imperfects circled in red. The 6 out of 9 molds aren't totally ruined but my original intent for the molds has been changed. The d6 had minimal to nonexistent bubbling/divots compared to the rest. Oddly enough my molds of my two 3d printed objects came out fine and there are a lot of ridges the bubbles should have caught compared to the dice.The silicone is fairly easy to mix. I meant to keep track of when it starts to set up to get a gist of its pot life(how much time you have to work with it before it starts to gel up/cure). It did cure in 12 hours, I let mine sit just a bit longer just in case. I have to say the silicone feels strong, not to tough especially if you do an encapsulating mold and have to cut the sides.I'm making a rough guess but I'm thinking the bubbles got caught on the edges of the dice I was making a mold out of which lead to the deformations. Possible the bubbles may not like items with somewhat intricate detailing, which surprises me as I've never encountered this issue before with other molds I've made. I did the usually moldmaking routine of a light spray of mold release and the needle pour into the lowest section of the mold to help reduce introduction and any further bubbles. So not entirely sure what went wrong.I've emailed the makers/sellers of the silicone, Let's Resin, and will update my review when I get a reply.I do recommend this silicone if you're trying out moldmaking as it's on the cheaper in for 'translucent silicone and other silicone in general. Though it becomes a milky white if what you're making a mold out of requires thicker walls. I do want to give this silicone another try since it does catch detail well on the dice as my photos show

Finally a clear silicone mold making kit that doesn't break the bank! VERY EASY to mix and use! (I'll add pictures soon). All my molds came out beautifully. My only complaint is that I wanted a larger size, but knowing the market that would be more $$.

The instructions were super easy to follow and and my first mold came out perfect! I had nevertheless molds before using silicone however I can definitely see making all sorts of molds now!
