GlassCast 10 is a water-clear, UV resistant clear casting resin developed for smaller or thinner castings such as jewellery, 3D resin-art, gaps/knots/wood inlays and more. It can be used to make parts up to around 10mm thick in a single pour making it the perfect clear resin for crafts.

Because GlassCast 10 has been developed as a casting resin and not a coating resin, it remains water-clear even in thick sections. It doesn't however, self-level to quite the perfectly flat, glossy finish of our GlassCast 3 coating resin and would require a flat and polish if a perfect finish is required on the open face.

GlassCast 10 Recommended Uses

  • Resin Jewellery - clear or tinted and 'secret wood'
  • 3D resin art - using layers, pigments and effects
  • Clear figurines or castings
  • Small scale blanks for turning
  • Thick counter-tops (up to 10mm) - with embedded objects
  • Simulated water on models or scenarios

GlassCast 10 Advantages

  • Incredibly clear - no epoxy beats it for clarity
  • Highly UV stable - GlassCast 10 is best-in-class
  • Natural air bubble release - almost zero trapped air without degassing
  • Low viscosity - ideal for intricate castings
  • Highly machinable - great for turning, shaping and polishing
  • 100% solids - zero shrinkage
  • No odour - VOC free

Ambient Temperature, Pot-Life and Pour Depth

The GlassCast range of resins, in common with all epoxies, generate heat as part of the curing process. The amount of time the mixed resin can spend in the pot, as well as the maximum depth it can be poured at, will vary depending on the ambient temperature.

For best results, we recommend working in a consistent room temperature of 18-20°C. GlassCast can be used in temperatures from 15 to 25°C but higher temperatures will reduce the pot-life and the maximum pour-depth of the resin significantly, as shown in the table below.

Ambient Temperature 15°C (minimum) 20°C (recommended) 25°C (maximum)
Maximum Time in Pot (Pot Life) 60 mins 45 mins 30 mins
Maximum Pour Depth 10mm 10mm 6mm
Initial Cure 48 hrs 36 hrs 24 hrs

Outdoor Use

Despite the very good advanced 'UV' resistant formulation of our Glass Cast resins, we don't suggest using the GlassCast range of resins for permanent, outdoor applications. This is down to epoxy chemistry meaning that eventually, over time, depending on UV exposure, environmental conditions etc, the resins will always eventually yellow in outdoor conditions. How visible this is depends on factors such as the underlying colour and conditions experienced.

We simply don’t have the longevity of testing to be able to guarantee how long it will be before the resin may start to deteriorate in direct sunlight, adverse weather conditions (freezing in winter, high temps in summer), water pooling or sitting on top, etc. We have got customers who have used it for such applications but the advice would be to either put the outdoor projects away between uses or to have a cover to protect it if no other product (yacht varnish, etc.) would suit your project.

How to Use

GlassCast 10 has been developed for professional users to produce the best results possible. It is not a 'craft' product and not intended for children. Before purchase, storage or use you must read the safety and technical data. Having said that, GlassCast 10 is incredibly easy-to-use and delivers fantastic results under a wide range of conditions.

GlassCast 10 is sold as a kit which includes both the resin and hardener. Take a look at our Resin Calculator to work out how much GlassCast you need for your project. When you are ready to pour, measure the resin and hardener at the correct ratio and mix thoroughly. Add any pigments or effects and then pour the resin - no more than 10mm deep - into your mould, cavity or wherever you're using it. The resin will reach initial cure in around 24hrs.

Getting More Creative - Pigments, Tints and Metallics

Although GlassCast 10 is often used completely clear it is also compatible with our complete range of tints, solid-colour pigments and metallic-effect powders. Many other colours and powders can be added too but be sure to conduct a test to ensure compatibility.

Yes, you can do an oven post cure of the coasters. The reason a post cure is helpful is that epoxy resins like these have a very long tail end of the cure when cured only room temperature. This means that over several weeks, the properties of the resin - including heat resistance - will develop as the resin cures fully. Typically after 7 days most of the resin is cured, however the post cure process will improve on that further as well as speeding up the process.

To do the post cure, you need access to an oven which has a reasonably accurate temperature control. The actual post cure cycle is to initially cure the resin for 24 hours at room temperature, followed by curing in the oven at 60° for 16 hours. Once allowed to cool to room temperature, the coasters will then be ready for use. Doing this post cure will give a heat distortion temperature of around 55 - 58°C which means you even less likely to get rings or marks from hot cups or plates.

If you are unable to get access to an oven for post curing, the resin does still perform well after allowing the resin a full 7 day cure at room temperature. Following a full 7 day cure, a very subtle ring may still be left by leaving an extremely hot cup to stand on the surface of the resin, this mark is slight and can usually only be seen if the surface reflection is inspected closely. Customers who use this resin for drinks coasters report that the marking is almost un-noticeable in practical applications and continue to use GlassCast commercially for coaster applications.

The GlassCast range of products are not designed for permanent outdoor use. Although the GlassCast resins have a very high level of UV resistance, the very high levels of UV exposure and the variety of inclement weather and environmental conditions experienced mean that the resin would degrade if permanently used outdoors.

Certainly, we can sell the resin and hardener separately if you need extra of either one one its own. Although not listed on the website we can do this over the phone or you can email us and we can send you an invoice with the correct amounts on it. The hardener for each of the GlassCast products is unique for that product. Using hardeners from other resin systems will cause serious curing issues or it may not cure at all.

Any mild soap and detergents will be fine for cleaning GlassCast Resin. Try to avoid strong acids or bases or neat cleaning products as it is possible they may dull the surface finish.

Hi Nicole, this would slightly depend on how you'll be making up that total depth. Generally speaking, flower preservation castings are done in at least 2 pours often more. At the very least, the first pour is usually used to provide a clear 'shelf' on which to position the flow so that it appears suspended in the final casting.

If you're doing multiple pours on a casting that will be a total of 7cm thick then it will probably mean that no single pour exceeds the 50mm maximum (per pour) for GlassCast 50 (when pouring into a mould) and so you could use GlassCast 50.

If you wanted to do the whole depth (50mm or more) in a single pour however then you would need to choose the GlassCast 50 PLUS. 50 PLUS allows you to cast up to 80mm (into a mould) in a single pour without the risk of the resin over-heating during its cure. This makes it great for big/deep castings and would make it a very safe choice for 50-70mm flower preservations but the trade off is that it does mean that it takes a lot longer to cure; around 7 days compared to 48hrs for GlassCast 50.

You're right to be thinking about this because the more metal powder you can get in the more genuinely metallic it will look. If you're measuring the metal powder in by weight then the maximum amount you can add will vary slightly between different metal powders, because their densities can be quite different. As a really rough estimate, you'll certainly be able to add the same weight of metal powder as you have resin - so into 1kg of resin you would add 1kg of metal powder, but you're likely to find that you can add more metal than that, especially for density metals like copper, brass and bronze. The absolute maximum would be about twice as much metal as resin but at this point the mix will be more like a thick slurry than a runny resin.

Unfortunately the GlassCast range of resins are NOT designed to be thinned in use.

Yes you can. Once the 10/150 surface has cured to a B stage, you can use GlassCast 3 directly on top. Alternatively if the surface has fully cured, key it with 120 grit sand paper and thoroughly clean prior to pouring the resin. To get a nice smooth finish, you would need approximately 2kg per square meter to ensure there is enough resin for it to self level evenly. GlassCast 3 used in this way will provide a high gloss and smooth finish that does not need further polishing.

GlassCast 3 can be poured over both GlassCast 10 and GlassCast 50 to give a smooth finish without the need for further sanding and polishing. The epoxy surface will need to be keyed with a 240 grit abrasive paper and thoroughly cleaned prior to pouring the GlassCast 3.

Hi Andrew, that's a good question. We tend to think of pen blank dimensions being a little less than the 20-25mm you're describing and in many cases there is a 'core' down the middle of the blank mould which means the resin doesn't occupy the full volume of the enclosure, which increases the section that can be cast without the resin overheating. When casting blanks that are more like 15mm, or a little larger if they have a hollow core, then in almost all circumstances you'd be fine using the GlassCast 10 and the higher reactivity would mean the blanks would cure more quickly (1 day compared to 2 or more) which for a lot of our customers is a significant advantage. However, if speed of cure is not really important, or you're casting blanks over 15mm or without a core then GlassCast 50 would be a better option. The two resins are identical, it's only the speed of the hardener that's different. In your case (20-25mm) it certainly sounds like GlassCast 50 would be the better option.

Both parts of the material (the resin and the hardener) are in bottles which are much bigger than they really need to be but that is because we have to use special UN approved bottles and packaging for resins and other Dangerous Goods and there are only so many sizes of these available. The weight on the bottle applies to the weight of the contents and the combined weight of the resin (Part A) and the hardener (Part B) equal the total kit weight.

GlassCast 10 is rated up to 50°C. This makes it unsuitable for use with very hot cups and plates. As such we would only recommend their use for decorative or colder temperature drink/plate use to prevent the part being damaged. Hot plates or cups may well leave a ring on the surface.

Yes the cured GlassCast 10 can be turned in a wood lathe and machined with woodworking tools in general. Allow a minimum of 48 hours to fully harden before machining begins.

Yes, steel brackets or other 'hard points' could be encapsulated into the lower portion of the pour either as is, or recessed into the wood for a flush finish. You would need to ensure the hidden surfaces are fully keyed on the plate to help with adhesion of the metal to the resin. Finally it would be necessary to drill and clean the threads with a tap to ensure the plate is effective.

Yes, you can certainly cast GlassCast into silicone moulds. Whether you should use GlassCast 10 or GlassCast 50 really depends on the thickness of your moulding at its thickest point. By 'thickness', we generally talking about the smallest of 3 dimensions at any point. So, for example, a casting that measures 30mm x 20mm x 3mm we would say is 3mm 'thick'. A casting that is 24mm x 20mm x 30mm we would say is 20mm thick. A sphere of 10mm diameter is 10mm thick. When casting into a silicone mould you can use GlassCast 10 for castings up to 10mm thick and GlassCast 50 for castings up to 50mm thick. If in doubt, go with GlassCast 50, it will still cure fine, in any thickness, but it may take a lot longer.

Yes you can apply varnishes over the top of GlassCast 10. We would recommend giving the surface a light key and thorough clean to aid best adhesion.

The resin will reach its full cure after approximately 7 days.

It would be possible to use the GlassCast 10 for a river table but the normal choice would be our GlassCast 50 Clear Epoxy Casting Resin product which was basically developed specifically for river table applications.

The reason why you would choose GlassCast 50 over GlassCast 10 for a river table is the thickness and size of the section. GlassCast 50 is designed for larger castings (up to 50mm thick in the right circumstances) whereas GlassCast 10 should not be cast in thicknesses more than 10mm, otherwise there is a danger that the resin could overheat during curing. If you check out the GlassCast 50 product page you'll find a whole host of information on using that product for a live edge river table.

We always recommend sealing a wood surface before coating with any of the GlassCast resins. This is because the resin can soak in displacing air and causing bubbles in the resin. Brushing a thin sealing coat of GlassCast over the wood and allowing it to fully cure will prevent this occurring. You would then just need to re-key the surface with sandpaper prior to your main GlassCast pour. Ordinarily you would use the same GlassCast product to seal with as the main pour.

Providing that the wetroom floor was fitted and used in the conventional way; i.e. it was occasionally wet and other times allowed to dry then - other than considerations around slipperiness - it should be OK to use GlassCast for this application.

My favourite resin to work with very clear. Bubbles go quickly with little effort. Minimal smell. Good working time. I've tried other cheaper resins but always come back to glasscast.

I really like this product and would definitly recommend it to anyone. This was my first go at making resin jewelry and I'm really pleased with the results. I will be making lots of Christmas presents myself this year which is much nicer than just buying things. The only reason I didn't give 5 stars is because I think the delivery cost is to high and should be free. Especially when you are just starting out £6 is a lot of money.

I use Glasscast 10 and Glasscast 3 for my jewellery pieces. I'm starting my own Youtube channel and will be showing other beginners how to make their own resin jewellery and I will always be using this resin. I like to include things like petals, seeds and other keepsakes in my resin castings and so the fact that this resin is really clear and bubble free is very important. Always fast delivery and help from the friendly staff at Glasscast when I need it! FAB : )

Great resin, works brilliantly with alcohol inks to create beautiful translucent peices like my gummy bear fridge magnets. I also use lots of other types of pigments and they've all worked great with no colour change or funny reactions. Definitely recommended for anyone wanting to start making they're own jewellery.

Glasscast is by far the best resin I've ever used. It's head and shoulders above the standard art/craft resins. I've used both the 10 and the 3 versions and they are both excellent, I tend to give a topcoat of 3 after the 10 has cured to give that amazing glass finish.

I started using Glass Cart resin after I found the other resins I had tried to lack hardness. I bought Glass Cast Resin following a recommendation from another resin Artist and I have been blown away at how strong the resin is once cured. I have tried the Glass Cast Resin 3 and 10 and I am a huge fan of them both. I would definitely recommend the product.

I now use Glasscast for all my resin projects. After trying a few different resins, on the quest for the best one, Glasscast is way above any others. I have used Glasscast 3 for my thinner pours like geodes, and top coating. The shine and glossiness is second to none. I also use Glasscast 10 for my castings of smaller pieces. I won't be using any other brand now that I have found "the one".

I’m a floral resin artist and would give glasscast 5/5, and more if possible. I use glasscast 10 and glasscast 50 and it’s by far the clearest resin I have found. Very easy to work with and I wouldn’t hesitate in recommending this brand to other floral artists.
