GlassCast 50 PLUS Super Deep Cast Epoxy Resin

In its in-mixed state (i.e. a bottle of resin and a bottle of hardener) then both parts should be considered toxic and handled appropriately (wear gloves and eye protection, work in a ventilated area, don't ingest etc.). Once the resin and hardener have been correctly mixed and fully cured then the end result is a stable and inert plastic that is not toxic. Being non-toxic is different from being FDA approved or 'food safe' however so we don't suggest making cups or plates but as a general description the cured end result is just a stable plastic material.

We would not recommend this resin for casting over projects such as a penny floor. However, we do have the perfect resin designed just for this application, our GlassCast Clear Epoxy Surface Resin.

Our GlassCast is a remarkable clear epoxy resin developed specifically to provide a beautiful, hard wearing, clear gloss surface for tabletops, bartops, decorative floor effects, furniture and creative projects, including projects such as your coin floor. The finish is very clear and has a high level of UV resistance so should look amazing for years to come.

All of our epoxy resins (including the GlassCast range) are safe to use on and will NOT dissolve or eat into styrofoam or any other polystyrene based foam.

Although fully cured epoxies are inert and unlikely to pose a hazard, none of the GlassCast range of resins are officially certified food safe and as such we cannot recommend their use where you would need the product to be certified food safe.

As long as the paint has fully dried then we would expect there to be no problems with the GlassCast range being applied over the water based paint.

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 100mm (into a mould) in a single pour with a lower risk of the resin over-heating during its cure. This makes it great for big/deep castings and would make it a good 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.

With the density being very close to 1, the 5kg kit is basically 5 litres by volume for calculation purposes.

Unfortunately not, the 50 PLUS resin uses a different formulation to the GlassCast 10 and 50 resins and so has its own hardener that cannot be interchanged with 10 or 50 hardener.

GlassCast 50+, along with the other resins in the GlassCast range, although not recommended for high temperature applications has been found to resist the heat from hot objects, such as coffee cups, very well and in a comparable way to other all resins on the market that we have tested including many that specifically claim to be ‘high-temperature’.

In common with all epoxy resins that we have tested, following a full 7 day cure, a very subtle ring can be left by leaving an extremely hot cup to stand on the surface of the resin, this mark is slight 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 3 commercially for coaster applications.

However, it should be noted that we wouldn’t recommend GlassCast 50+ for coasters based on their thickness; 50+ is a deep casting resin and very slow curing; its likely that when poured at coaster thicknesses, the cure time could exceed 7-10 days so would be impractical. GlassCast10 is the more often used option for coasters.

Although we believe that our resin performs very well in coaster applications we recommend that customers do their own tests to ensure that they are happy that the resin performs to their requirements, to the best of our knowledge there are no other readily available clear resin systems that have distinctly better performance.
