Customer Testimonials

Confidential Art Casting Client, USA
"I love the product!!! I cast one small item just to see how it would come out and it's great. It's so user friendly and forgiving. Shell removal was so easy compared to what I'm used to." 


Confidential Art Casting Client, USA
"Great product. Very simple to use, the shell doesn't crack – it’s nice and strong."


Richard DammHantverksministeriet AB, Sweden

"It works like magic. Did some casting in aluminium as well, with perfect results. Thanks for your support."

Ian DanielsIan Daniels, UK

"After trying different methods of making a mold, with no success due to the total weight of brass being poured (34 kg), I tried SuspendaSlurry and lost wax. I used 2 coats of zircon and 8 coats of fused silica and achieved the best results so far. The shell was very good."

Daniel Droney

"Many thanks to R&R for making my first bronze cast an easy and enjoyable experience. This is the installation in Sarasota, FL, named Gulistan, cast using your SuspendaSlurry. My clients liked it so much, they have already ordered another spout! I hope more people will use this and achieve the same results."

"I am very happy with the SuspendaSlurry material. I cannot tell you how grateful I am to not be required to drive 40 minutes to my school and save the tank every time we lose power (which in CT, seems to be every other week). I would also like to say, the main reason I switched to R&R is the fact that you folks are easy to get information from and are responsive to your customers."

Paul KennedyPaul Kennedy Studio, UK

 "I have spent a frustrating year mixing Primcote and Molochite -200 to create ceramic shells in my studio with inconsistent results. Looking at the waste, time and effort to achieve mediocre results, I was getting to the end of my tether. 

SuspendaSlurry material arrives and I am tingling with anticipation, four waxes are run up awaiting investment. Two are for a new client that I have been talking to for a year and finally he has given me the opportunity to cast his work. The other two are my own work and as such I am less stressed about casting these.

Dip, flick, Zircon, smile, dip, flick, Zircon, smile, dip, flick, Molochite, smile and continue investing with a huge smile. De-wax and cure and a beautiful white shell emerges glowing red with NO CRACKS! The molten bronze flows into the ceramics and then it's a wonderful tense atmosphere in the studio waiting to see the results.

Hammer and chisel in hand, I make the first strike and start to reveal the solid bronze piece encased in its running system. I run my eye over it and can see nothing obvious, but with experience, I know I have to wait until I sand blast it to make sure everything is OK.

I could literally cry with happiness as I see four perfect (and I mean perfect) casts sitting on the chasing bench with the sun glinting off them. After cutting the running system off, I only needed to chase these areas. It was an absolute joy saving so much time and not having to chase any defects that I normally encounter. 

When I delivered them to my client, he was so impressed he placed another order immediately and complimented the chasing! 

I hope that explains my experience with SuspendaSlurry! It's a joy to work with and although it's extremely satisfying chasing faults, it's far better to simply create a beautiful cast.

I thought this was a better explanation of my feelings than just "Oh it was OK". Thank you for your advice on the phone and look forward to many more successful investments.

I will obviously be ordering again!"
