Glowing caldron

This will work imagine you place the glow inc sak in the caldron and it’s like the water when you use it it has 4 stages I believe it will be awesome if this happened to the glow inc sak if you put 1 inc sak it will give 4 levels of light and if you put 2 inc sak It will give you 8 level of light and 3 inc sak 12 light level and the last thing if 4 inc sak this will be the finale stage it will give a light level of 15 , or you can just craft it like the Glowing  item frame.
