Where?! I cant see it there mate

[digger]

How much are you after? I have a bit left in stock. PM me with your requirements if phill can't help you out.

Sodium Silicate solution.......... 6th one down mate?

[Karl Mitchell-Shead]

I there not a difference between Sodium salicylate and sodium silicate?

[Karl Mitchell-Shead]

Sodium salicylate is a fuel in bezolift (superior to sodium benzoate) sodium silicate is used to fireproof isnt it?

Yep you have got it. Sodium salicylate makes a superior whistle from a burn rate point of view (although it does have to be protected from atmospheric moisture as it sucks it in given half a chance)

Ahhh yes I missed the spelling didnt I! Oopsie.

[Karl Mitchell-Shead]

thanks anyway

For what it's worth, I've made 'benzolift' with Salicylate and with Benzoate and the marginal performance difference does not really justify the much higher price of Salicylate.

[Karl Mitchell-Shead]

Fair comment, i'll give it a go inline with testing and evaluation anyway but likely stick to benzoate

[digger]

I tend to agree Phil. Definitely not worth it for benzolift, probably a hindrance as it will absorb moisture sat in a lift cup.

However I find the difference in performance is worth while for use as a shell break booster. It makes all the difference I feel in this application so that flash does not need to be used in smaller shells. This obviously gives the advantage that you don't get the white flash when the shell breaks which is particularly important when using some of the more delicate charcoal based effects (as it effects the sensitivity of the eye for a few seconds diminishing the visible effect, not noticeable on film).

One thing I have found is that the only time to make salicylate whistle is on a nice hot summers day. At any other time it will get wet when you are evapourating off the Colman's fuel.

If you are looking for a booster use potassium sorbate instead. It is as powerful as whistle, but you can buy it at wine making shops easily. Just be careful, it is incredibly powerful, and just a tiny bit too much will break your stars.

If you are looking to make whistles, just use potassium benzoate and iron oxide - it works excellently as any consumer grade whistle does. It has a slightly sweet odor, which you might also notice from storebought whistles on careful dissection.

Interesting tip. Thanks for that one. I will give it a go.
