Hi,
I have bought a small baking tray that came with a plastic lid, as a precipitation container... My question is, should the container be closed when it is in the freezer with the naphtha(q21q21's tek)?
How hot the water should be(in the lower bowl), should I just put there straight some boiling water, or should I wait for it to cool down? Or: If I just put the tap water at maximum temperature, will it be sufficient?
And is there any method to test if the freezer is cold enough -without a thermometer?
Thanks
