Water for D76 from electric kettle?

[Odot]

I wanted to save some time and decided to heat up the water (sink) in a electric kettle and simply added cold water til i got the temperature right. Is this ok?

While we at it, what if the temperature is a few degrees lower? Just curious what effect it has on it.

Thanks.

For your location should be none. Make sure it is all diluted. I found it is little bit colder it takes extra effort to dilute it completely.

Shake shake shake, shake shake shake

Probably not a good idea, but can be saved. It probably has quite a lot of salts floating, so filtering it is a must. Few degrees lower shouldn't make much of a difference, perhaps it will make things slightly harder to dissolve.

Should be fine as long as the kettle is clean and no contaminants can leach into the water. I use a stainless steel pot to heat a quantity of water, then mix with cold to get the approximate final temp before adding the powder. A few degrees off shouldn't hurt, but if it's too cold it'll take longer to dissolve. Best to stir quickly without shaking, as you don't want to diffuse too much air into the liquid.

With temperature you'll get into bigger trouble going too hot than the instructions ask for, you could potentially destroy the reaction.
With too cold it's just harder to get the mix together, sometimes impossible it too much colder.

I think you'll be fine with your kettle, warm water is warm water no matter where it got warm from.

In the past I have warmed very cold water in a microwave. My 800w microwave will warm cold water (about 40f) up to around 75f in around 25 seconds. Then add the correct amount of developer concentrate (Rodinal) and dilute to full volume which by then it is now about 73f. Add this to a cold developing tank and you are about at 68f just right to develop the film.

Just let your developer and other solutions come to room temperature (18C - 24C) and work at that temperature.
The developing charts give you the times. Or use the developing dial in a Kodak Darkroom Dataguide.

OP - I assumed you were asking about mixing your stock D-76 from powder, since it requires a fairly high water temp.

If mixing the working solution from stock, I just keep everything at room/tap temperature which is usually between 18C - 24C for me.
