    This question comes through email by Marie:

    Hi!  I love watching your video tutorials and learning new tricks for working with resin!
     
    I
    would like to ask, I have a silicone shot glass mold and I would love
    to make resin glasses but I can not find anywhere if the epoxy resin
    would be food safe once cured?
    I know that it is used for bar tops but that is all I can find.
     
    Do you know the answer to this? or where i could find the answer?

    Hi Marie,

    Great question!  Before I comment, let me make sure I have all the facts possible about this. 

    Give me a couple of days…

    Marie,

    This is the response from the manufacturer of the Castin Craft clear epoxy resin and the Envirotex resins:

    That use would be termed ?extended food contact?.  These products have FDA approval for just ?casual food contact? which would tables and countertops.

    Which specific product is the food safe resin? I’m new to this, but do need an extended contact food safe epoxy resin

    Hi Kathrine,
    Not sure if this thread is obsolete but will try at least. Seeking similar application to the one described above, but need the resin to adhere to (fully cured) concrete. Have poured a series of concrete cups that I would like to use as coffee cups but am struggling to find a sealant / resin that is food safe for “extended food contact” (as above) where heat of beverage is not a problem.

    Also need to know if your products are available in the UK.

    My thanks in advance,
    GGM

      Hi Geoff, I would expect this same resin would work well for concrete, but the manufacturer hasn’t tested it for the temperatures that I would expect coffee to be at when first poured.

      If you are still interested in the resin, we can ship it to you in the UK.

    Hello, I wanted to thank you for the information in this thread, Katherine, it has come in very useful for me! I do have another question, if possible. Do you know if the Alumilite Dyes are also food safe/food grade? When mixed with the Alumilite Amazing Clear Cast Epoxy Resin?

    If the Alumilite dyes are not food safe, can you recommend other food safe dyes or alternatives? Food coloring?

    Thank you so much!

      Hi Dylan,

      Unfortunately, the Alumilite dyes do not have the food safe designation, not because they are unsafe, but simply because the manufacturer hasn’t done the required testing (which is expensive). I don’t have a good food safe coloring alternative for you. Food coloring generally doesn’t work well in resin.

    Hi! I am planning to make a mold for Ice cubes for my water bottles
    and wanted to know if the Alumilite Casting resin was Food Safe for making ice
    and if the molds would be able to withstand freezer temperatures. If this is
    not the product,what would be the best product and what would be the
    best mold putty/rubber to make the food grade ice cubes?

    Hope to hear from you soon, thanks!

    Hello, I want to make a beer glass with items embedded into the glass. I see the type of resin you recommend that is considered to be food safe. Do you have a suggestion as to how to make the mold that would have at least a 1/4″ wall thickness to be able to completely embed my items.? Any and all help would be greatly appreciated.
    Thanks,

    Hi Bob,

    You are either going to need a glass in the size/shape you want to serve as your template or you will have to make something (3-D printed or otherwise). Once you have your template, you can mold it like shown here in this video from Composimold: https://www.youtube.com/watch?v=Jv4jwK-BbRA It also shows how you can cast it as well.

    Your second option for molding, is to place your template bottom into the bottom of the mold box. Pour the molding material so it covers the top the glass by an inch or so. Demold the glass. Your molding material will have to cure stiff otherwise the mold will collapse on itself and not take the resin very easily.

    Good luck!

    Response from Bob:

    Summary of what I think I need to do.

    Make a female cavity mold of the outside of the glass and then a male, smaller plug for the inside
    of the glass. I need to suspend the plug in the cavity mold using toothpicks, (somehow) then
    as I pour the resin into the mold, insert my items into the resin and be careful I don’t come in
    contact with the outside and the inside so they don’t poke through.

    Does this sound about right?

  • #7861 Reply

    You got it Bob! If you are working with a very stiff silicone, making the two parts is unnecessary as a stiff silicone won’t collapse on itself while you are trying to pour the resin.

    You would probably do best to try to suspend the ‘male’ part of your mold from above.

    I would love to see pictures of your finished project. Please share!

    Hi, Can I make a female mold of a glass, then brush on a thin layer of resin to the wall and let it harden, then another thin layer of resin to this thin “skin” of resin and while still wet ,embed items onto it. Let this harden and then pour another layer of resin to encapsulate these embedded items. I want to confirm that pouring multiple layers of the same resin will permanently bond to each other and also not leave any witness lines from one to another. Thanks for all your help

  • #7963 Reply

    Good news — applying layers of the same resin to each other will bond fine.

    Bad news — there isn’t going to be an easy way for resin to stay on the wall of the mold. Gravity is going to work it’s magic and pool it at the bottom.

      Hi
      Good and bad yes, but….. I am going to be patient and try painting multiple very thin layers of resin to slowly build it up. I have lots of patience when it achieves something really cool. Or, is there a way to adjust consistency of the resin and make it a little thicker? Or can I apply the thin layer of resin on the walls and use a hair dryer to speed up the drying rate? Thank you for your info.

    Hi Bob,

    Unfortunately, in this case, there is nothing I would recommend to adjust the consistency of the resin. I’m glad to hear you are willing to be patient. 🙂

    A hairdryer or heat gun can speed up the process, but once again, be patient. There can be ‘too much of a good thing’ in this case. If the resin gets too hot, it can cure very quickly, but with bubbles and/or a cloudy appearance.

    I would love to hear how this works out for you.

    Hi Katherine,

    I have polished coconut cups (https://s-media-cache-ak0.pinimg.com/736x/49/43/ec/4943ec74928d38637fdb1a641fc71a35.jpg) that I want to use to serve cocktails in at our wedding. Unfortunately the liquid leaks through the shell and I was looking for a resin that I could apply on inside / and or outside that would be safe for my guests to drink from.

    Would the Alumilite Amazing Clear Cast Epoxy resin be safe to use?

    Many thanks,

    Hi Alana,

    Yes. https://shop.resinobsession.com/collections/resin/products/alumilite-amazing-clear-cast-epoxy-resin-16-ounces

    This resin is designated as FDA food safe once cured as per FDA CFR 177.2600. Resin must be mixed 1:1 by volume (not weight) in a smooth sided cup to ensure complete blending. Allow a full 7 day cure before using castings for food purposes. Pieces are suitable for cold or warm food contact only. Cured pieces are not dishwasher, microwave oven or conventional oven safe.

    Hello, i am planning on coating a wooden mug in your amazing clear cast food safe epoxy, it was going to be used for cold and warmer liquids, i want to confirm that it is ok to hold liquid in it for some oeriod of time once fully cured? For example 2 or 3 hours? Also theoretically what could happen outting hotter liquids into an epoxied item? Would it melt? Or uncure in some way? Need to make sure if its limits thank yoh

    Yes, you can put cold or warm liquids in it for an extended period. While I haven’t specifically put very hot or boiling liquids onto/into resin, I know from experience that too much heat from a heat gun will make it soft. LOL I suspect that is what could happen here too with hot liquids.

    Hello! I’m wanting to coat the interior of a glass goblet that I’ve silvered (the way they make mirrors) and I’m wondering if the resin will change the color of the silver at all. Is it okay to use on metal (albeit a thin layer)?

    Also, for those wanting to use the dyes in the resin and still have it be food safe, one option could be to use the dyed resin as the first layer and then after it cures, coat the colored layer with a layer of the clear, un-dyed resin. Just an idea!

    Yes, you can apply resin over the silver without changing the appearance.

    Hi Katherine!
    I saw you recommended this product to somebody interested in making food safe shot glasses, and I just wanted to ask a few questions: https://shop.resinobsession.com/collections/resin/products/alumilite-amazing-clear-cast-epoxy-resin-16-ounces?variant=1195651921
    I have a small plastic container that I would like to make safe to use as a shotglass, for spirits of no more than 40% abv. If I were to lightly coat the inside of this object with the amazing clear cast expoxy resin, am I right in thinking the object would be safe for infrequent use as a shotglass?
    Thanks 🙂

If I use the dishwasher safe mod podge with glitter on mugs, glassware and tumblers, do I need to use a food safe resin to cover both the glitter and the vinyl wording on the items?

    You don’t have to resin the outside, especially since the Alumilite resin is not dishwasher safe. However, if you want coat the tumbler with resin, then a food safe one is the best choice.

    Dear Katherine
    I have a fruit bowl with lots of embedded small pretty tiles, but it is these bits that bruise the fruit. Could I paint a layer, let it cure, then add another layer, after layer, after layer? Unfortunately I cannot just pour it over otherwise it will just fill up. Also it is a strange shape. I am concerned that gravity will just make it all pool at the bottom. I saw this lady paint the insides https://www.youtube.com/watch?v=R8MiPis8K7I

    Hey Katherine,

    I was wondering how the alumilite amazing would go for wood saturation of a timber mug/spoon/bowl. I want to keep the timber look with minimal epoxy sitting on the surface. Is the resin thin enough to soak into the timber, or would it be possible to thin it a little with some acetone and then let it soak in and evaporate off? I was after a tougher, more permanent seal than wood oils but a similar look.
    Cheers

    Hello I bought the envirotex lite I want to coat the outside of a tumbler cup that I coated in glitter Is this specific one FDA approved and safe for the cup since it will be on the outside only and there’s a lid to the cup so no one will be putting their lips directly on the cup where the resin is

    Hey, love what you’re trying to do here.

    But, are you aware that the FDA does not have a “food safe” designation?

    I believe one of the reasons for this is that by declaring a product “food safe” the FDA would then assume a liability for future problems. Thus they would get buried with litigation.

    What the FDA does do for food surfaces and containers is to list which materials and percentages of materials are prohibited or allowed for contact with said surfaces. Also, “Some” materials are declared to be for occasional contact/use.

    Then we(hobbyists, retailers, manufacturers, and importers) have to compare the MSDS to see if the item in question contains prohibited materials or prohibited amounts of a specific material.

      Hi Holden, thanks for your concern about the food safe designation. This is the official statement from the manufacturer about the Amazing clear cast resin:

      This resin is designated as FDA food safe once cured as per FDA CFR 177.2600. Resin must be mixed 1:1 by volume (not weight) in a smooth sided cup to ensure complete blending. Allow a full 7 day cure before using castings for food purposes. Pieces are suitable for cold or warm food contact only. Cured pieces are not dishwasher, microwave oven or conventional oven safe.

    Ms Swift,

    Thank you for your timely reply.

    I read Alumilites page concerning their product.

    They specifically stated in the last sentence of the description, “Complies with FDA CFR 177.2600 “.

    This is good, right, and legal.
    This is also very different from claiming something as “FDA food safe designated”.

    Now, The FDA has a G.R.A.S. (Generally Recognized As Safe) list for individual/specific items(ingredients /chemicals). But items which are GRAS do not /can not convey GRAS status to other items/ingredients. Also it is possible for 2 GRAS items to produce something not GRAS..

    What I’m getting to is that the FDA to my knowledge does not issue “FDA food safe designations” nor do they issue “FDA Food Safe Certifications” for food additives, which also encompasses linings and surfaces that may leech into foods they come in contact with. To my knowledge there is no “FDA food Safe Seal” for resins, liners, and containers.

    Companies can label items food safe, state they meet FDA standard xxx.xxx.xxxx…….

    It’s the addition of FDA to the beginning that is problematic.

    Now Alumilite by their page does everything correctly.
    My quick review of their order page is as follows.

    Pros::
    Listed their product as meeting FDA guidelines
    Have a MSDS PDF on the same page
    Have a Technical datasheet PDF on same page
    Volume calculator
    Bar Top instructions
    and
    Tech Spec’s list

    Cons:
    MSDS is doesn’t list all ingredients due to “proprietary blend claim,
    No list of items known to break down the resin (alcohol, sugars sugar water, acidic foods or beverages, ect, ect,…).

    I’ll most likely do some independent testing to see what if anything breaks down the resin after it’s set.

    Hope this clarifies my point.:)

    Cheers

    P.S. Looking forward to working with some Alumilite alongside the Max CLR we’re about to test.

    Thank you for a very detailed explanation. I have been trying to tell my nieces this, now I have something concrete to refer to and show them. I have been leery of the “proprietary blend” claim, but unsure how to explain my doubts. My nieces think if it says “certified FDA compliant”, it’s automatically safe for food use.

    Hi there… I am so sorry to be a bother… I haven’t gone through all of the questions and comments.

    However… I am just now starting to learn about resin. I had first seen the epoxy resin. When trying to find some non toxic resin I found this page.

    I want to make table/counter tops… Lamps… Floors… Children’s table… But… I need to know that my children and other children I make for will be safe. Don’t trust the fda. Sorry. And I am very against toxic chemicals and their use.

    I found this resin called art resin which is supposed to be a nontoxic epoxy clear dry resin. Though I’m not sure if I can use it for counters, lamps, floors etc.

    So… What non toxic resins are there that I would be able to use for anything really?

    Thanks so much x
