In a student laboratory, baths can be hazards if they spill, overheat or ignite, because they have a high thermal inertia (meaning they take a long time to cool down) and mantles can be very expensive and are designed for specific flask volumes. Two alternative methods for heating glassware can be used instead. One method is to suspend glassware slightly above the surface of the plate with no direct contact. This not only reduces the temperature of the glass, but it slows down the rate of heat exchange and encourages even heating. This works well for low boiling point operations or when a heat source's minimum temperature is high. Another method, called a teepee setup because it looks a little like a tipi, is to suspend glassware above a plate and surround the flask by a skirt of tinfoil. The skirt should start at the neck of the flask and drape down to the surface of the plate, not touching the sides of the flask, but covering the majority of the plates surface. This method is for glassware to be heated at higher temperatures because the flask is warmed indirectly by the hot air collecting under the skirt and unlike simply suspending the glassware, this method is better protected from drafts. Both these methods are useful in a student laboratory as they are cheaper, effective, safe, and the user does not have to wait for a bath to cool down after use.

I'm pretty sure any other integer wouldn't make sense, and that this doesn't need to be specified — Preceding unsigned comment added by 108.86.234.251 (talk) 07:13, 22 May 2017 (UTC)[reply]
Aren't the (usually four) plates on a hob or stove called "hot plates" as well? Otherwise, what do you call them? Thank you. 2.202.159.91 (talk) 14:24, 2 September 2019 (UTC)[reply]
My brother, Brian Lowenthal founded a company in Chicago back in the 60s that manufactures capital equipment, including industrial hot plates. Here's the line from its web site:
"Our industrial hot plates, first, developed in 1998, are now sold across the world to a wide variety of manufacturers, mining companies, and universities."
https://www.wenesco.com/about-us
I originally developed the site and was the webmaster for 20 years. At my urging, Brian wrote the content for Wikipedia in order to make the article more useful and comprehensive. I edited the text a bit and then inserted it into the article. I did NOT want to cite Wenesco as the source, because that seemed self-serving to me, but <ref>https://www.wenesco.com/wenesco-hot-plates is what I cite to a curious visitor.
Brian passed a few years ago and his family sold the business last year.
Many other companies also manufacture industrial and special-use hot plates that have nothing to do with keeping baked beans warm. You can find them in searches by using such key words as Industrial Hot Plates, Butt Fusion, Heated Chucks, and other terms named in the article.
Given the nature of business today, the verifiable fact that companies from Chicago to China manufacture such items and promote them on their web sites may be the only way to establish the existence of industrial hot plates. I know of no articles about the subject. LarryWiki115 03:08, 10 January 2020 (UTC)
