The Perfect Epoxy for Resin Flower Preservation
GlassCast 50 is sought after by professional and hobbyist flower preservation artists who require thick section (up to 50mm), clear casting resin that cures bubble-free, has excellent UV stability and is compatible with a wide range of pigments, dyes and decorative effects.
GlassCast 50 was designed to be self-degassing and to produce bubble-free castings without the need for a pressure-pot or degassing chamber, leaving you with super smooth castings!
Why choose GlassCast 50 for resin flower preservation?
- Crystal Clear – no epoxy beats it for clarity.
- Self-degassing – natural air bubble release, without degassing.
- Suitable for thick sections – Cast up to 50mm depth in a single pour.*
- No odour – VOC free.
- Highly UV stable – Best-in-class protection from yellowing.
- Widely compatible – Works great with most pigments, dyes, and effects.
Getting Started
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 (minimum) | 25°C (minimum) |
|---|---|---|---|
| Maximum Time in Pot (Pot Life) | 80 mins | 60 mins | 40 mins |
| Maximum Pour Depth into a thin walled mould (silicone/plastic) | 50mm | 40mm | 30mm |
| Maximum Pour Depth into wood or an insulating mould | 25mm | 25mm | 18mm |
| Initial Cure | 96 hrs | 72 hrs | 48 hrs |
What to Cast Into
There are a number of options to choose from what it comes to what to cast your blanks into.
- Silicone Moulds – pre-made silicone moulds are available in a variety of shapes.
- HDPE moulds* – Alternatively, some suppliers offer sturdy HDPE plastic moulds in various sizes.
* Repeatedly casting epoxies into silicone or HDPE moulds will cause the moulds to degrade. Using Vaseline or similar as a release agent has been found to be very effective at extending the life of both silicone and rigid plastic moulds. Using moulds of this type means that you will undoubtedly need to finish and polish the casting.
How much resin will I need?
The amount of resin needed to cast a piece will vary depending on the size of the flowers (and other items) being placed into the mould.
Use our handy Resin Calculator to work out how much GlassCast 50 you will need.
How to Use
GlassCast 50 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 50 is incredibly easy-to-use and delivers fantastic results under a wide range of conditions.
All flowers (and other natural objects, like for example fir cones) must be fully dried before being encapsulated in resin. To learn about the drying process, read our Flower Drying Guide.
GlassCast 50 is sold as a kit which includes both the resin and hardener in their correct ratios. The resin and hardener are mixed together at a ratio of two parts resin to one part hardener by volume. Because GlassCast 50 is designed for thicker castings, it needs to cure more slowly than other GlassCast resins and will take around 48hrs to cure.
Always download the Technical Datasheet from the 'Downloads' tab for full details on correct measuring, mixing and use of the product.

Customer Product Reviews for Epoxy Resin for Flower Preservation
Perfectly clear, bubble-free resin that produces consistent results. As a premium product, it does suffer with crystallisation, but always returns to water clear after sitting in 60+ degree water for a while. Minimal shrinkage is also a big plus point.
Fantastic product, great at degassing for bubble free castings, good machinability when cutting, turning or shaping/carving.
Great. Super happy. Fast delivery (came next day) and thanks to Charlotte in the office who helped me to find the delivery (at my own house!!
I've been using glass cast 50 since the beginning and have now produced nearly 20 river tables and similar projects. I tested a few other resins in the beginning and settled on glass cast 50 because of the cure speed and bubble free finish. Other resins I tested for river tables were much too slow to cure. One took a week to cure and still felt too soft to machine properly. Great product.
TOP PRODUCT!! have used Glasscast 50 for 3 river tables now, they have all worked perfectly and great technical support from Warren who helped me figure out a problem I was having with tiny air bubbles (was caused by jiffy mixer - dont use one!). Great product, great service.
brilliant product, really happy with the end result, did exactly what it said on the tin. only reason I didn't give 5 stars is because it would have been better if I could buy a 2.5kg kit, the 5 was too big and the 1kg is too small.
No comparisson! Glasscast 50 is the only epoxy resin i will use for my river tables. quality of the product is spot on - bubble free, cures hard, machines great, polishes great. What more can I say? 5 star product.
I have been working with resin for quite a while now, using various resin products, with varied results. After trying GlassCast, I have found a product I'm sticking with. Easy to work with, easy to finish. Night and day from others I have used. Highly recommended.
Highly recommend! Great products supplied via great service. Top quality all round. Will be staying with GlassCast and not even tempted to look elsewhere!
