Monday’s post will be up by noon.
Please note that I am permanently changing Thursday’s post day to Friday.
My goal is to publish new posts twice a week — Mondays and Fridays. However, if you don’t see a new post on Friday, it’s because I was too busy, so please look for a new one the following Monday.
Every once in a while, I will re-post one of my most widely viewed blogs of the last nine years. This is one of the top three, originally written on September 14, 2009.
Having sold many thousands of antique glass vases over the years, I’ve learned a lot about how to clean them from trial and error. It also doesn’t hurt to have a Master’s Degree in Chemistry.
Most people are quite timid about using chemicals on glass. They’re afraid they’ll ruin their vases by removing the decoration or somehow damaging them. There are very few times this would actually be true. Cold-painted decoration on a vase could be ruined by the use of some chemicals but Tiffany Favrile vases and French cameo vases by Daum, Gallé, and others have no cold-painting, so all of the steps I describe below are appropriate. If you suspect that your vase has cold-painting on it, test a small area with one of the cleaners below, using a Q-tip. If any color comes off, stop and use only the mildest cleaners.
Eco-House citrous thinner
The first step is to remove any sticky substances, which will dissolve in organic solvents such as mineral spirits or acetone (nail polish remover). There are also some good commercial products available, such as Goo Gone, available at stores like Home Depot or Office Depot, or online. Another product I like is citrous thinner, made from orange peels. It smells a lot better than the other solvents and is quite effective. Click here if you’d like to order it.
Start by looking for anything sticky with your eyes and your fingers. Put very little solvent on a Q-tip, rag or paper towel. Rub the affected area until the dirt or stickiness is gone. Mineral spirits is a gentler solvent than acetone, so try it first. Mineral spirits is especially good for removing the gum from old labels. Use acetone second, if you need a stronger solvent. These various solvents will also remove crayon, sap, or any similar substance.
Easy-Off Fume Free
Next we’re ready for aqueous cleaning. I suggest you do this in a sink. Most of the cleaners will make your vase slippery, so be very careful not to lose control and break it. The gentlest cleaners are dishwashing liquid or Windex. I like to use them with an old toothbrush. Scrub the vase with the first cleaner and see if the dirt comes off. If it’s stubborn, you can proceed to the next level of cleaning power with commercial products like Scrubbing Bubbles or Dow Bathroom Cleaner. Repeat the process. Spray the vase, let it sit for a few minutes and clean again with a toothbrush or similar brush. If that’s not strong enough, you can go to the highest level of cleaning power — Easy-Off, of which there are two types available. The blue can, labeled “Fume Free” is the one I recommend. (It’s not really fume free, but it’s not too bad.) It’s powerful and should remove any leftover dirt. Finally, rinse your vase thoroughly in plain water and dry completely with an old towel. If it’s safe, let it dry upside down. It’s a good idea to use gloves to protect your hands, an apron to protect your clothing and glasses to protect your eyes. Easy-Off in the yellow can is lye (sodium hydroxide). It’s very powerful. It will eat through the dirt nicely, but also through your clothes and skin, and can severely damage your eyes. Immediately flush with plain water if you have an accident. You’ll know you’ve gotten it on your skin if it feels slimy.
To clean the inside of your vase, you’ll need various brushes to reach hard-to-get-to areas. Just use one of the sprays above, let sit, and brush away. Justman Brush Company sells hundreds of different brushes.
A sick vase whose glass has been etched on the interior
Vases that have been filled with water can present bigger problems, such as scratches on the interior. The second and more serious problem is sick glass, which includes etching of the glass interior or the depositing of lime or other minerals. Etching will appear as frosting, while depositing will appear as white crust. Cleaners will not effectively fix these problems. The only real way to treat problems of this sort is to go to an expert who can “tumble” the vase to resurface the interior. It’s basically the same as sandpapering the entire interior — great for a transparent vase, but not as good for a vase that has a finish on the interior, like an iridescent vase. Use this link for Paul Nulton, who used to do this kind of work, but may or may not still be in business.
Sometimes vases were kept in homes where the owners smoked or had smoky fireplaces or stoves. The vase will probably appear to have dingy color. With a minimum amount of effort, the results can be quite gratifying, revealing unexpected bright and beautiful colors!
Good luck! (Have a good story to tell me? Please send it to philip@chasenantiques.com)
Our next show is not until May 18-20, 2018, when we’ll exhibit at the 2nd edition of the resurrected Chicago Antiques + Art + Design Show at the Chicago Merchandise Mart. It’s a wonderful venue for a show that deserved to be restored from purgatory.
We’re still very much in business between shows, so please don’t hesitate to email or call. I recently listed some of the new items on my website and will list more every week. Click Philip Chasen Antiques to take a look. I will make every effort to actively list new items as often as time permits. I always strive to offer the finest objects for sale on my website and at every show. There are many items for sale, sold items with prices and free lessons about glass and lamps. And remember to keep reading my blog.
By the time you read this post we’ll be on our way to Asheville, NC, to exhibit at one of our favorite shows of the year, the 31st National Arts & Crafts Conference at the Grove Park Inn, this coming weekend, February 16 – 18. It’s a great show that I recommend you make the effort to attend.
By the time you read this blog, we’ll already be in warm, sunny Miami for the opening of the Miami Antiques + Art + Design Show this Friday, February 2, 2018. It opens at 11 AM and closes on Sunday at 5 PM. The weather is predicted to be in the 70s all week. The show will feature over 200 premier exhibitors from the U.S., Canada, Europe and South America, offering the finest antiques and decorative arts. It’s a very high quality show that is worth a trip from anywhere in the world (and clients do fly in from as far as Japan).
After a few rough years of the show getting smaller, a serendipitous series of events led to the show growing again. Last year the show grew to 200 dealers from only 60 the previous year. This year the show has stabilized at 200 dealers, as many of the dealers from the Original Miami Beach Antique Show decided they would only exhibit at one show in Miami due to the temporary relocation of the Original Miami Beach Antique Show to the Miami-Dade County Fair & Exposition Center. (Supposedly the show will be back in the Miami Beach Convention Center in 2019. We’ll see if that materializes, but more on that later when I hear the scuttlebutt in a few days.)
