While making sodium silicate Na2SiO3 I used Silicon gel and mixed it with a heated solution of sodium hydroxide. Unfortunately the glass beaker I was using,...
on my ceramic hob...yes on my ceramic hob...broke. The solution quickly ate into my hob :( no use crying over spilt sodium silicate I guess.
Maybe this will forewarn others and perhaps save them my misfortune ;) c'est la vie

Expensive sodium silicate :D

Was the glass beaker boro-silicate glass? Ordinary glass will often break under extreme and rapid temperature changes. It is important to insure that when you buy chemical glassware that it is boro-silicate.

Thanks for the advice Yvain. I guess it wasn't boro-silicate as the little glass recepticals I was using were for putting tealights in. I got six for fifty pence...a bargain ... Not :)
