I have been making a few wooden plates on the CNC machine & using glasscast to fill any cracks, knot holes & splits in the wood as it is food safe. Works really well but now I have been asked by a Restaurant if I could make them some live edge steak platters from wood that they can provide that has a significance to either them or the Restaurant ( not sure which but not important lol).

Problem is that although Glasscast is food safe I have been told by someone that it is not dishwasher safe & since these will be washed in an industrial dishwasher it's quite possibly not going to be an option.

So my question for the experts, Is what I have been told about it not being dishwasher safe true & if it is does anyone know of a clear food safe resin that is dishwasher safe. 

I suspect it is going to be the temperature that is the issue at the very least.  GlassCast is rated to a maximum working temperature of 55C so i would be also concerned if a hot "sizzling" steak went straight on it that it may damage the resin too.

On the "food  safe" front, although cured epoxies, in almost all cases, are totally inert and hence  can in practice often be considered "food safe", in the formal food industry,  the term food safe would need to be backed up by some independent  testing and certification particularly if it is to be sold or used with the public.   GlassCast does NOT have any formal "food safe"  certification. so you need to be careful  about how you word  what you say to a restaurant or similar .

Thanks for the reply, not so sure the placing of hot food will make to much difference since I am just using it to fill small cracks & not as an overall finish coating but the certification does bother me, I had been led to believe that GlassCast was food safe, by that I mean it had a certification. If it doesn't then I am going to have to look at some other clear resin that does have a food safe certificate. Seems to be quite hard here in the UK to find something, easy with a google search to find resins that are FDA approved but not so easy to find something that carries the same sort of certification for the UK
Since a lot of the items I make are to be sold then this is something that is important to get right.

ArtResin® Epoxy Resin is the only resin we have with an FDA approval for incidental food contact.  It is a bit too soft for chopping boards etc but will firm up a bit with a post cure at around 60C.  However it is limited to around 10-12mm thick as a casting resin.

Thanks for taking the time to reply Warren, I shall have a look at that & do some experimenting. I am really looking for something that will fill small cracks & splits in the wood rather than a deep coating or an overall covering, Plates I make are generally finished with a food safe oil rather than a resin coating.
I use the resin to fill minor damage to help prevent cracks/splits from getting any worse & also to prevent bits of food & general dirt getting into them,

The ArtResin should fill small cracks and splits just fine.  It is not quite as runny as GlassCast but it does still have a long pot life so will soak in where it needs to before it sets.
