Sublimation HACKS - Sublimation INSIDE of the mug? 

dont think the insides and the bottom are coated with a sublimation coating which is why it fails. There is a sublimation spray that you can use which may work on the inside but as it stands I dont think it's a time or weight issue

Normally, cups are never coated with polymer on the inside! Because this coating dissolves when in contact with hot liquids and this is carcinogenic

Thank you for doing this! I just watched that video with the sand before yours and I had such high hopes for using my Cricut mugs and press to print the inside. Thank you for doing this because you just saved me time and materials!!

That would be super cool if you could do that, however, is the ink food safe, or safe to drink from? I wonder if the inside is even coated for sublimation, and if the coating would be safe? Also, I know they make the spray to coat items and make them sublimate, but again, I'd worry about safety with that!

I was also thinking that the mugs might not be coated on the inside. One way to get around that would be to coat the inside of the mug yourself. However, I'm not sure that's safe. My concern is that the solution might contaminate any liquid you would put inside the mug. I read one review on Amazon that said that PolyGloss Sublimation coating is FDA compliant once it has been cured. And then I read another one that said it has not been tested for food safety. I'm not sure what to believe.

Me too! Inside of mugs are probably not coated. Cheaper to make the mug that way; and sublimation is normally done on the outside 😉

i believe most sublimation mugs and tumblers only have the outside sublimation ready, especially since the inside goes in contact with food and drinks

I agree with most of the comments on the post - no sublimation coating on the inside. I doubt if Cricut would do that because the Mug Press isn't intended to print the inside of a mug. Also, it seems to me, I heard that the bottom of the Mug Press does not heat.

I agree with the other folks here....the inside is not set to be sublimated. However, either is COTTON...we use film right? Why not try it with film? The sand in a bag is good - keeps the mess down. Just a thought.😁

I would love this for decoration only but not sure if i would drink from it. I really wanted it to work. Maybe we can try a sublimation spray so it will stick or maybe use a smaller heat safe cup and fill that with sand and place it inside the cup. You have my mind thinking now lol.

Hi there, loved the video & have 2 questions , 1, where did you get your tape dispenser from ..?? 2, where did you get your heat proof gloves from ...??

thank you for the tutorial. while watching, i had an idea. not sure if you want to try it. but what about using cheese cloth or canvas to hold the sand. like in a pouch of some kind. like when you make a sandbag. i dont know what sandbags are made of but a mini version should work the same. or maybe a bag of heat rocks? really small ones to add weight? just an idea.

I love that you posted a failure, it saves us work! I imagine the sublimation chemical is not in the inside of the mug.

What about laying the subli-shrink onto of the inside image, heating the subli-shrink then filing with sand? Maybe try the cuo press and oven again trying that?

Is the inside of the mug treated for sublimating? Would that be safe to have contact with hot beverages? If so, what if you filled the mug with sand very full to the top, then placed a heavy disk of some sort that normally would fit inside the mug, but you put it on top of the sand, pressed it down and added a shrink wrap around the mug from top to bottom? Do you think that would be enough pressure?

I was wondering the same thing, is the inside of the mug sub coated but also if you wanted to retry it, maybe load the sand inside a heatproof bag first and that way, you could press the bag inside the mug so it's really tight against the sides maybe and see how that goes but would there any health issues with the ink coming off and being ingested over a period of time?

I believe the inside is not coated for sublimation. Also, the thoughts about it being a carcinogen or not good safe… if it isn’t food safe they wouldn’t put it on a substrate that is intended to come in contact with your mouth. A lot of things are toxic to you until they are cured. For instance, you aren’t going to lick liquid glazing for ceramics. But after it has cured properly you can use the mugs, bowls and plates that it’s applied to. There may be other issues with a liquid sitting inside a mug that has been coated and cured, but I doubt that as well. There are plenty of other sublimation items that come in contact with food, like plates and trays and such. Sublimation plates are not just for decoration, unless specified. Just my 2 cents! 😊

I’m guessing no sublimation coating inside mugs. If you use a spray, I’m guessing you need to make sure it can be used with food/drink.

Is the paper you printed the outside design on special paper or just regular print paper?

I saw another crafter that had sublimated pictures inside his mugs but he did not do them, he buys them pre-done so he doesn’t know how they do it either. I’m sure it has to have the sublimation coating on it but I wonder if they bake it after sublimating to ‘gas’ off anything left inside the mugs?

Maybe use a c-clamp and a round disc and create the pressure. Similar to when we push brake cylinders back in.

I'm not sure if anyone has suggested putting a paper weight or some kind of weight onto the image and then putting the sand on top of it. Then, wrap the mug.

Great video,I'm curious if you can sub on the outside bottom of the coffee cup with the cricut mug press?

I wonder if there is a silicone insert created for the inside of the mugs. Various sizes, of course. If not, that’s something that I think would work well for this process. What do you think?

Maybe cricut should come out with mugs with a nontoxic sub coating on the inside and a hand held heat tool that fits in the bottom. It would be nice if there was a nontoxic coating we could put on and a heat gun would be hot enough. Then we'd just need to transfer the heat through pressure somehow. I'm not mechanical or enginerical 😂 but I'm sure someone in the crafting world can figure it out.

please tell me what kind of tablet you are using i love the size. thanks

sand would apply enough pressure so that is not the problem. its definitely not coated for sublimation on the inside, you should do a test using subliglaze

Can you make a sand bag for the inside of the mug?

Like people said no poly coat on the inside so pressure does not matter.

Bummer, I was hoping it would've worked. Thanks for trying

I've seen plenty of videos that use the convection oven with just taping the design on the outside of the cup and it working with no extra pressure. I believe it's just not able to be done on the inside unless it specifies it can be done.

I wonder if it would work if you place a weight on top of the sand

Can I ask which brand is your oven?

Good attempt. Where it failed is the inside mug does not have the sublimation coating. All sublimation mugs have a special coating on the outside, not the inside. But, good try😎

can u use sub design with infusible paper? or are there designs on there own for infusiable paper and ink?

In the thumbnail picture, you have the inside sides sublimated. Is that just a mock up picture? Or did you actually sublimate the inside sides?

I been a member and I have the option to use Design Scape but never really have because I don’t know how to I have tried but just gave in would be nice to see more videos out there on how to use it

Is the inside treated to take sublimation ink?

Can you use small rocks

Add Some Rocks maybe, Just an idea. Or put it on outside bottom of the cup and tape it down tight. That being said, I think a few people just posted the correct answers below Thanks Chrystal

Just a thought, but could it be that the inside of the mug is not sublimatable?

I also think it’s that the inside of cup does not have a sublimation coating. I don’t know if a sublimation coating would be food safe or not.

I believe there is no coating on the inside of the mug. Maybe you could use a poly coating on the bottom and then do it again. Thanks!!!

I wanted to know if it is food safe?

Is there a type of scissor that can cut out round items? would be faster ☺

Hi great video we need a like a branding hot tool that has a circle wide enough to fit the inside of the mugs with cord on top of handle thank u an 💡 👍

I got an heat iron tip for my wood burning tool that is flat and it works.

Thanks Dawn 😊

The inside of the mug is not coated with plastic. So it won't work, do I see that right?

Is this safe? To drink out of? Chemicals?

My thought was another glass filled with sand and taped down for pressure, but still agree that I would'nt drink from it

It cannot be sub until it is coated inside the mug. And because the coating is carcinogenic, they don't coat the inside of the mug.

There is not a sublimation coating on the bottom of the cup. That's why it does not work it has to be coated

I agree with @stephenantcliff9127 I've watch the CHINESE videos on how they coat the cups and they set the cups on Peg from the inside as they sprayed the outside... So I think you are on the right track though!! Great Video!

Would it be that the inside is not coated with the sublimation finish?

How do we know that the mugs are sublimated on the inside?? I believe that this is the big question. Unless you can confirm tha,t I don't see this ever working

What if you made mini sand bags to fit in the cup?

Thank you for trying this out. I'm fairly new to sublimating so I don't know all the ins and outs but I would think you would not want your drink with the sublimation (because of the gases) so maybe that's why it doesn't have a coating. That aside, for pressure I liked someone's idea of heated rocks. I was thinking about the sand tho, what if the sand was damp or wet. Sand is heavy but wet sand might make it more compact and even heavier. You could always put some parchment paper between your sublimation paper and the sand so it didn't get wet at all. It's just a thought I had as I watched. 🤷 Thank you again for your videos. They are always very helpful. ☺️ Happy Thanksgiving!

It's not the pressure, it's the lack of sublimation coating on the inside of the mug.

Try putting the sand in a sock or or cloth bag.

Where do you get the paper you shrunk around the mug?

Would that be safe?

It would be helpful if you gave us sizes in your videos of the template

Thank k you.

Perhaps spray the bottom with sublimation spray.

How do you sublimate the bottom to add logo?

Maybe the inside doesn’t have the polymer for safety.

Is this food safe though?

Thanks

There’s no poly coat inside for it to press to

I believe the inside is not coated with sublimation...

What about putting a weight in the bottom

apparently, you have to have a 3D Vacuum Machine to sublimate the botton of mugs also using sand

I don’t know how you gonna hit send hot enough in that amount of time

Well a few people already mentioned it. But the inside isn't coated for sublimation.

Does it work to sublimate in a regular oven? 🤔

The inside has no polymer coating to accept the dye.

I hope it worked

Wonder if rocks would work 😊

I agree with the others, maybe the mugs are not coated for sublimation

There is no heat being applied to the bottom inside of the mug.

Usually the inside of the mug is not coated for sublimation

I doubt that Cricut coats the inside of the mugs with the sublimation chemicals.

I don't think it's coated, possibly for safety reasons. 🤔

I think that the mugs do not have the sublimation coating on the inside.

Ok. I saw on you tube how to print your favorite photos inside of a mug but he use a vacuum press . I think that's what it's call . Check it out at Technic Guru . I think the video is a few years old.

Correct the mugs are not coated for sublimation.

Maybe they don’t have the coating on the inside of the mug

The problem is not pressure its no coating on the inside of the mug

I don’t think the inside of the mugs are coated for sublimation

Try a vacuum sublimation machine🤷🏻‍♀️

The insides may not be coated...possibly not safe to drink from

I don’t think they’re coated inside which is the actual problem.

My thought is that the inside was not meant to sublimate

Try ball bearings

I use my 3D vacuum press easier and works every time 😁

Maby when you try it with tape and no sand

Oh that's right it's not treated for sublimation in those areas just read someone's comment

They have branding hot tools but not a plain big circle 🔴

I don't think it's coated on the inside.
