    Default How food safe is diggers casting and embeding resin

    I am needing to fill some cracks in a new timber chopping board that I am making out of silky oak. Iam looking at either leaving them with no finish or applying walnut oil. I waswondering if the casting and embedding resin is food safe or is there is anotherresin or filler that I can use.
    Cheers Pat

    I don't know if it is food safe, but I wouldn't use PR on a cutting board anyway. Being a cutting board that is generally soaked in oil, the fact that PR doesn't stick that well and knowing the wood will move, it may not stay in place. PR is also very brittle and against a knife blade you will end up with shards of resin as it chipped.

    Hopefully someone else might suggest something, I personally wouldn't fill it, I'd resaw out the cracks and then glue up again possibly with laminates.

    From what I can find, PR is not a simply a single chemical but a class of compounds. So, some PR is not food safe, some is not recommended for some types of food exposure and others are just fine. It seems, if you want a PR that is food safe, you need to look for Isophthalic Polyester Resin. However, I don't know who makes one.

    Personally I would not fill it but have you thought of hard beeswax? You can melt that into the cracks and wipe of excess with a soft pad with some oil. At least if it is natural beeswax you know it wont be harmful.
