I'm very confused by this review. This dildo certainly is made of glass, it should also have the same ability to hold temperature as well as other glass toys.

It is made from Borosilicate glass.
I have other higher quality glass toys that hold heat longer.

PolyGrrl, I've prepared the following information about Borosilicate glass, so I can share it with any new reviewer who doesn't understand the nature of Borosilicate glass:

Borosilicate glass is a type of glass that consists mainly of silica (SiO2) and boron trioxide (B2O3), which makes the glass more resistant to drastic temperature changes and high resistance to corrosion by chemicals. Borosilicate glass is popularly used in the production of scientific instruments such as laboratory glassware because it can handle both extreme cold and heat. It used to be the choice of glass for kitchenware as well. However, many U.S. kitchenware manufacturers have switched to use soda-lime glass because it less costly than borosilicate glass; for example, glass bakewares manufactured by Pyrex and Anchor Hocking. If borosilicate glass undergoes an abrupt and severe temperature change or falls on a hard surface, it might still crack. But, it cracks in chunks instead of shards, which is much safer than soda-lime glass. Therefore, all high-end glass toys use Borosilicate glass.

I hope the above information helps!

I understand the nature of Borosilicate glass.
There is nothing wrong it this type of glass toy.
I have a hand blown glass toys that holds temp. a bit better that is all.

That's great! I'm glad you've ultimately discovered that the material, borosilicate glass, of your Rainbow Nubby Wand really is glass. These sentences in your Material/Texture section confuses your readers: "This toy is glass(ish). It is not real glass, otherwise it would be 3X more expensive."

Oops, sorry about the typo, it should be "confuse" and not "confuses"!
