Production of acetone from egg shells and vinegar

I learned from these [wiki](https://en.wikipedia.org/wiki/Acetone#Older_methods) [pages](https://en.wikipedia.org/wiki/Calcium_acetate#Uses) that acetone can be produced from calcium acetate, which can be produced by the reaction of eggshells and vinegar. However, I couldn't find the required temperature. Would it be possible to produce acetone vapours by simply heating calcium acetate over a natural gas flame (~1500 degrees C)?




Calcium acetate decomposes starting at around 160 degrees Celsius, according to [Wikipedia](https://en.wikipedia.org/wiki/Calcium_acetate "Wikipedia"). So yes, it is definitely possible to do so in a gas flame.
