fridge, freezer & microwave signs

Hi all,

I need to make up signs for our fridge, freezer & microwave to make sure everyone knows that they are used with chemicals & therefore should not be used for food. I'm feeling a bit brain dead this morning, so does anyone have some they could post here for me please?

Thanks so much!

Yay!! :clap3: It has set already, next time I won't be so impatient & I will wait for it to boil before adding the agar... thanks again for all your help everyone!

Re: Phenolphthalein Agar

I reheated it, and already it seems to be setting! Big improvement on yesterday's effort. I don't think I heated it enough before adding the agar, but at least that is 1 mistake I won't be making again! I'm too impatient for my own good sometimes... Thanks everyone for your input, very much apprecia...

Re: Phenolphthalein Agar

Bugger!! It didn't set. Will it set if I heat & add more agar? Or should I cut my losses & start from scratch??
