That is a lovely painting. I like the way it draws the eyes into it. It must look wonderful on a wall at your home.
What is earthquake wax?
It is this WAX substance in a jar (I've seen it in sheets, too) where you grab about a pea-sized ball of it (roll it into a ball). It is quite sticky. Then attach a few balls, depending on item size, to the bottom of the object. Press against the surface you want it to adhere to and flatten. Adhesion! It anchors quite well.
You can liberate the item by using dental floss or monofilament line to "saw" between the surface and the item. What is nice it does not stain or leave a residue after you peel it completely off - using a credit card or similar to get the residual off. I have stuff stuck to my wooden fireplace mantel and have moved stuff over the years. The WAX can be reused - just roll it back into a ball. The gel loses its clarity if you try to reuse it
Now, I have a different stuff - earthquake gel which I don't like as much. Apparently, it does not last as long and apparently dries out and should be reapplied. I have not got there yet with the two applications where I used it. But is is completely clear whereas the wax is cloudy (but generally unseen on the bottom of items).
Gel holding glass to protect newel top of bannister. I need to reapply it with less gel to make it a bit neater. Ignore my toes in the bottom of the picture!
I have not been able to find the "Quake Wax" online - maybe a different name or company. I first purchased it in the LA area (makes sense) years ago. That jar has enough to anchor a house!
Here's what the WAX looks like
There! All you need to know about earthquake protecting your glass art. I've actually used it to adhere a door bumper to a molding trim on a vertical surface - improvise. The wax is still holding after seven years! It is a very small, light bumper.
