Potters & Sculptors - Making Rock from Mud
I'd normally pour the glaze for the inside of a pot, but I've made a couple of biggies - 17" tall, 12" diameter, the aperture at the top is 6". I don't make large quantities of glaze and even if I did I'm not sure I'd want to fill one of these and then up-end it.
The best option that I can think of is to spray, but I'm never happy spraying the inside of things, although to be fair I've not tried with anything approaching this size.
Any thoughts or suggestions?
One is bisque fired and the other is still green, hence the different colour and size.
About 1/4 of the volume of your pots (or even less) should allow you to pour a liner glaze. Pour it in. Swirl to get the glaze as high up the inside as possible, then start pouring out slowly while rotating the piece to cover the upper inside. The correct outpouring rate and rotation rate will completely cover the upper inside surfaces in a single outpouring. If you don't get all the way around the pot, add enough glaze back to the interior to complete the coating. This is a skill that you can develop with practice. You might have to clean off some drips on the outside due to the liquid glaze clinging to the rim and outside.
Spraying the inside of any closed form is not a viable option.
Thanks George, I know the technique as that's pretty much how I do internals now, although I do use more than 1/4 of the volume, I'm slightly concerned about the problems of moving that size and weight quickly as I try to be fairly quick so as not to get the glaze too thick.
I think I'll have to give the pot a good wetting before doing the inside.
