Can any glass go in oven?

I've bought the glass bottles for my very first glass painting however I am not sure if the glass can go in the oven??? There's no oven safe stated under the glass!

Glass Bottles

If the glass is not damaged it will be safe in the oven. Be sure to read the label on the paints to heat cure your project at the correct temperature.

In the oven
by: Anonymous

Be careful, sometime some pieces are glue like the handle of a pot, so with the heat it could fall or brake in the oven.

Sorry if my English is not correct It is my second language but I am painting on glass for the last 10 years and sell it in art craft show.

Good luck

NOT ALL GLASS IS OVEN SAFE
by: prairiesunshine

After a phone conversation with a helpful rep at Plaid, I learned a few things. I told her I was buying glass at the dollar store to create painted glass that LOOKS like depression glass rather than having to buy expensive depression glass.

She told me that BLOWN GLASS can't go in the oven but other glass could. She said that items that were usually blown glass were vases. She said wine glasses and other drinking glasses, bowls and other glass items are usually safe. Now whether or not this info is TRUE, I have not been able to ascertain yet!

Blown glass has to be air cured, not oven cured. I'm doing an internet search again to find out for sure how to tell the difference between blown glass items and other glass.

Every time I do a search on painting on glass, this website pops up. It's a wonderful site! I'm SO glad I found it!

comment permission

Of course you have my permission, what an awesome opportunity!

I have never had the opportunity to take a fine arts course in university (I'm almost 100% self taught) but I wonder if any part of it involves science courses?! Because as artists, we sure do some neat experiments!

I hope you'll have a chance to test this theory before you print the article. Find a blown glass vase at the dollar store and give it the old college try! ;O) Of course I'd LOVE to know the results!

Thanks for such an awesome resource!

My goal in life is to be able to teach what I've learned. Spreading the joy and wonder of art would be an amazing legacy...

Baking beer bottles
by: Anonymous

My husband found beautiful blue beer bottles (not painted blue). Do you think it'd okay to put them in the oven to set gloss enamel paint? Is it safe to use my regular oven? Thank you

Baking hand blown wine glasses
by: Anonymous

I purchased iridescent wine glasses from family solar. They seem to have the pontil marks on the bottom. Some sites say you can bake these at 200° but others say no. I use water base acrylics. Has anyone baked this type of glass?
