Hi,

im an fine art undergrad from london.  im looking for chemicals thats will react in either heat or sun light or the from sunlight. preferably changing pigment from clear to a colour and visa versa. could any one advise me on which chemicals could achieve these effects and where to obtain them from and give any advise on safe application and use?

many thanks

the link above may be what im looking for, 408 could you tell me where i might be able to get a sample?

You will have to buy or make 1-amino-1,2,3-triazole and react with sodium dichloroisocyanurate(pool chemical).  Pretty sure no one sells the actual compound as it is explosive (although not enough to really worry about handling it).

do you think that would be easy enough for a novice without a purpose built lab and if so where would i find instructions and components?

by the way thanks for the help.

Holy crap, dude, he's going to blow himself up.

Look up photochromic dyes

It is less sensitive than PETN.  Safe to handle with basic precautions...

Now this on the other hand  http://pubs.acs.org/doi/abs/10.1021/ic200071q  photochromic as well, except not as significant color change.

I enjoy trollin' people on the interwebs as much as the next man, but recommending explosive pigments to art students is kinda scratching the bottom of the barrel.

thanks for the comments. what im actually looking for is something that i could apply to a surface vie a pump and spray garden device, that would otherwise just look as though it was water but then after a short time in the sun appear as a colour. does this help narrow it down. also i should mention that i would prefer it not to stain.

I would recommend looking up "photochromic dye". These are compounds which react to light by changing their color. I believe there are commercial products available which do this.

could any one point me in the direction of where to source the photocomic dyes from?

also i found this online.

it looks perfect for what i want but perhaps a bit to new and possibly expensive. could any one put me in touch with the developer? thanks.
