I don’t think any paint is safe around one’s mouth, but I’d also be concerned if the mouthwash came into contact with the paint: would it affect the paint? It might. An idea might be to paint such a bottle only part of the way to the top, thus keeping the top clear glass only to be safe. I hope this helps!

Hi Debbie,
You can actually make a nice frosted effect with these sea glass paints instead of etching. Using a stencil, you can create some nice frosted effects. Combining the sea glass paint with etching cream isn’t a good idea because the chemicals will mix and most likely not give you the result you want. In terms of washing, here is what the Plaid Crafts company suggests:

Can I bake-to-cure Martha Stewart Sea Glass Paint on a glass surface to make it permanent rather than air drying 21 days?

Yes, the bake-to-cure method of curing Martha Stewart Sea Glass Paint is the best way to create a permanent and washable frosty, sea glass effect on glassware. Begin by allowing 24 hours of dry time after the paint has been applied. Next, set painted glassware in a cold oven, set the temperature to 350°. Bake the painted glass for 30 minutes then turn the oven off. Do NOT remove the baked glassware; allow it to stay in the oven until completely cool. When using this technique, allow the painted glass to both heat up and cool down with the oven.

How should I clean a project created using Martha Stewart Sea Glass Paint?

Once baked to cure to a glass surface, Martha Stewart Sea Glass Paint can be hand washed.
NOTE: Do not allow a painted surface to soak in water.

I hope this helps!

Hi Deborah, Unless you can find these paints online (on the internet) I’m unsure where to purchase them at this time. Because of the pandemic, it is hard to find certain products these days due to shipping, manufacturing, and so on. If I learn anything new, I’ll post it here. Stay well!

Where can I buy these paints? Michaels in San Diego doesn’t carry them

Hi Christine,
I’m not familiar at all with the craft industry in Australia, so I decided to do some searching on Google. I found something called CraftOnline.com.au which bills itself as Australia’s largest online crafts superstore. They seem to carry a paint called FolkArt Enamel Paint in Frosted Aegean Sea. It looks like that is a frosted glass paint which should give you a similar finish. (Go to their website and search for “sea glass paint” and you’ll see it.) I also searched on Amazon’s site specifically in Australia and the Martha Stewart Paint is sold on there.

Hi Sandy, I’ve never tried using this paint inside of a glass bottle, and checking with my fellow bloggers not finding anyone who has tried it specifically with this paint. I think part of the beautiful effect of this paint is the texture you see and feel on the outside of glass bottles once it is dried. I don’t think the texture would be seen well at all if it was used on the inside of glass bottles because you would still have the shine of the glass on the outside. I hope this helps. And by all means, if you try using it on the inside of glass bottles and love it — please let me know!
