Luminous flame produce deposit on the bottom of the beaker because when the beaker is near the flame, it limits the amount of oxygen for the methane, thus, the deposit (which is Carbon), is produced.
A luminous flame causes the beaker to have soot at the bottom and the luminous flame also does not heat it up properly.
Because if you use luminous flames the beaker you use will have a soot at the bottom and it does not heat it up properly but instead of using non luminous flames it will be heated properly.
Put it in a beaker. Use a smaller beaker filled half way with ice and water and place in the larger one. It should be about and inch or two obove the mixture. Heat over a bunsen burner and the Naphthalene will deposit on the bottom of the smaller beaker.
Water can be condensed on the bottom of the glass cover.
It is important to let the sand settle at the bottom of your beaker so that the sand is separated from the liquid.

Decreases!
to get an accurate reading of the liquid inside the beaker, the thermometer should not rest on the bottom of the beaker.

differentiate luminous flame from non-luminous flame
Inform their teacher and then throw the beaker in the broken glass
at the bottom of the beaker
hotter
The sides or bottom of the beaker will likely be at a significantly different temperature than the liquid.
