This resin is great!
By Kathryn Phelps

I tried the new Resin8 1 to 1 Epoxy Resin for embedding, doming and filling some deep bezels. Having tried a few types of resin over the years, I knew exactly to sort of problems working with resin can bring, and what I wanted this resin to do for me.

Shrinkage. It did not seem to ‘condense’ or shrink whilst curing, or if it did, it didn’t do so quickly. This meant that if I had sprinkled glitter all the way around the edge of a central design, the glitter did not move towards the centre of the piece as the resin condensed. This has been a problem with the other type of doming resin I use, so I’m delighted with that.

Doming. The resin domed beautifully and consistently. I had the right amount of control when using it; it was not difficult to encourage it to spread and dome over the entire surface, but it did not run over the edge.

Hardness. My resin bugbear and my weakness; getting resin to set as I want it. This has been my only consistent problem with resin, but finally feel as if I’ve got it: this resin set rock solid! I can sell these pieces knowing that they are hard wearing. I do not take any chances whatsoever but the extra steps paid off: I warmed the resin in a pot of hot water before use. The pieces then set in a hot box; for me this is just a closed cardboard box with a desk lamp inside, which gets really warm.

Bubbles. This resin did produce a few bubbles, but I got rid of them all using a blow torch; I think a lighter can be used as well. My deepest piece was about 6mm, so deeper pieces might behave differently, but for me, it was fine.

A big appeal of this resin is that it comes from a source who know everything I may want to know about this resin, because they formulated it: The Resin8 team. I also like the fact that it is primarily for jewellers. The resin worked perfectly first time, but if I have any future hiccups it’s good to know that I can ask them about what I may have done wrong. (Do not watch Netflix whist measuring resin is my own personal top tip ;-)). It also means that I can now use resin from only one stockist: if there’s one thing I’ve learned, it’s that you need to learn the quirks of each type of resin, so switching brands and types is not something I want to do. I now use 1 to1 resin for doming, and Slow Cure Epoxy resin for casting and for when I want a long time to work on my pieces.


No scales required!
By Michelle Fernandez

For the last 5 years I have used a standard resin; which is measured out by weight at a ratio of 2 parts resin to 1 part hardener. I use electronic scales to do this and when teaching I have noticed that many of my students struggle with this. The new Resin8 1 to 1 Epoxy Resin is measured out by volume instead of weight in equal parts. Equal amounts of resin and hardener are poured into two measuring beakers (eg.5ml resin and 5ml hardener) and then these are mixed together. For this reason I am sure many people will find this much easier to use. Use two measuring beakers, fill to the same line; one with resin, the other with the same amount of hardener, then mix together. Note that, with very small quantities a pipette and a very steady hand will be needed!

The resin is quite thick, whilst the hardener is runny and has quite a strong odour! However, this lessens when they are mixed together. Always use nitrile gloves, and work in a well-ventilated room. Being quite thick, bubbles are easily produced so stir carefully and slowly in one direction. It pours easily and the bubbles can be removed with the careful use of a lighter over the surface. In this way I was able to produce lovely, bubble free domes on a pair of earrings (image 1) and due to the viscosity the dome did not collapse as the flame passed over it.

The resin blends very easily with colourants and although not suggested for casting with, it produced perfect bubble free castings from a silicone one-piece mould (image 2). Again run the lighter over the surface once the mould has been filled and leave to cure. After 24 hours it parted easily from the mould.

Although it has a thick consistency, much like a thixotropic/gel resin, when I tried to fill the recess around a ring shank it became quite runny and dripped (crept) much more than a gel resin (image 3).

I think this is a good all round resin. Fine for doming, mixing with colourants and even for casting if care is taken to remove the bubbles! That scales are no longer needed is definitely its biggest advantage, making it easier to use than some other resins.


It does exactly what it says on the tin!
By Kate Sinclair

I love the new Resin8 1 to 1 Epoxy Resin, it's amazing and so easy to use. Simply measure one and then add the other. The curing time is more than enough to get some lovely results with. I made a couple of nice cabochons with some and the doming was great, it looks really professional and I was really impressed. To coin a phrase "it does exactly what it says on the tin".  It's another great product from the Resin8 team and far easier than other resin I've worked with, I can't praise it highly enough. I will definitely be using more, I just wish my pocket could keep up with my ideas as they've definitely been flowing since I opened my 1 to 1 resin kit!!!


A great resin, easy to use, fantastic results: love it!
By Beads of Creation

I found the Resin8 1 to 1 Epoxy Resin really easy to use. The measuring is so simplistic, a lot easier to measure by volume leaving less room for error. There is an odour but it makes you less lazy about health and safety issues e.g. keeping the room your working in well ventilated etc as you have a constant reminder you are working with chemicals. The consistency meant I didn't need to add an extra doming layer, the resin is thick enough to do this in the first pour. I did cast with it as well and loved the results.

I added angelina fibres fused together in one pendant, glitter and mica powders in another and finally mixed another batch with alcohol inks. The resin cured in 24 hours and has a lovely shine.

All in all a great resin, easy to use, fantastic results, love it!’


I definitely think this is the resin i've been waiting for!
By Wilde Works

Having worked with various epoxy resins in the past and very happy with the ones I currently source from Resin8, I was intrigued when their new 1 to 1 Epoxy Resin surfaced on my radar. So much so, that their call for testers drew me in like a giant magnet. I couldn’t resist. I had to respond, and just a few days later I had a reply! I was on their shortlist! I was thrilled to bits! Was this the resin I’d been waiting for? I certainly couldn’t wait to test it on my new design!
I was both excited and apprehensive. The specs stated 10-15 minutes working time, which wasn’t very long. I’d have to be quick. Also, we were warned that the resin might be bubbly: one bubble would ruin the entire effect. On the positive side, and this is what had caught my attention, the resin promised to be great for doming and cling well with a thick gel-like consistency. It was also non-toxic with no solvents – definitely a bonus!

The time had come. My handmade silver test piece was ready. All masked and gloved up with the snazzy blue nitrile gloves provided as part of the test kit – why take any health or safety risks that can be avoided – I was eager to start.
The 1 to 1 volume of resin to hardener certainly made things easier to calculate. Only, I couldn’t find how much opaque pigment to use, so I gambled on the ‘no more than 5% pigment to quantity of resin’ specified for the resin I normally use for the first two colours, but used less pigment to resin for the third colour (about 3%), simply because it was the last of my batch.

I was pleasantly surprised that mixing the pigments into the resin produced far fewer bubbles than expected, which quickly dissipated when left to stand. I tried both warming and not warming the resin beforehand, but as it was a hot day the difference was negligible. Adding the hardener created no bubbles at all; it poured in smoothly. The resin had no detectible smell, but I was glad of my mask when mixing in the hardener!

As the new resin promised to be gel-like, I decided to work on half of the ring at once, rather than just a small section as I would normally do. Although it didn’t feel very gel-like when mixing, it was true to its promise and adhered perfectly to the sides of the ring! Another welcome surprise was that the working time was longer than expected: at least half an hour. I left the resin to cure and regularly tested what was left in the mixing cup to monitor its progress.

After about three hours the resin had reached the thick treacle stage, so, pressed for time, I decided to move on to the next colour. This time, knowing how well the resin adhered and how much working time I had, I felt confident enough to fill the entire ring at once with one colour and then moved on to the next several hours later. I left the resin to cure overnight.
The next day, with less than the recommended 24 hours cure time, the resin with the highest proportion of pigment was still slightly tacky. The 3% batch much less so, but – not surprisingly – not cured enough to sand and polish before the deadline. Luckily I had prepared a small batch of 1 to 1 resin (with less than 3% pigment to resin), which I’d dropped into some teeny tiny studs a few days earlier as a shadow test. These sanded and polished up nicely.

I would fully recommend using Resin8’s new 1 to 1 resin for small-scale resin casting on curved surfaces and I will definitely use it again. Its adhesion and working time were far better than expected. Also, the dreaded bubbles weren’t an issue. The lower pigment to resin ratio produced a harder result, but the colour was less intense. Although I haven’t tried it, I would be interested in testing Resin8’s new 1 to 1 resin with their Resi-Tint acrylic pigments, of which you only need a small amount (approx. 1 part per 1000) to transform clear resin into long-lasting vibrant colours. That way you can combine the best of both worlds!
