Chemistry set DIY gas mantle? Answered
I'm looking for some help tracking down a chemistry experiment I tried as a child and would like to replicate. As I recall it involved dissolving a solid (perhaps limestone) in a liquid (possibly vinegar), soaking some cloth in the resulting solution and burning it over a flame when it dried.
The idea was that the cloth would burn away and leave a mesh of whatever it was, probably lime, that acted as a mantle. I tried it as a child and had limited success (I was too impatient to get some appropriate cloth or wait for it to dry properly) and would like to try it now that I'm older and
If it does have to be limestone, any ideas how I can hold of small quantities without having to go to the local chalk quarry?
