Thanks for the input everyone..
Just trying to get ideas.. This piece is a trial piece that I made about 6 years ago while I was still in high school.. It's made every tank move with me, and is one of my favorite decorations. It's not only functional, but looks very natural and blends well with the environment compared to a pot not designed for aquaria use.
Oddball - I can definately make those forms, up to about 2 ft tall.. (kiln limits my max sizes).. I can put the breaks anywhere you'd like, and can glaze almost every color except deep reds..
Not only will I be attempting to produce a wide variety 'sunken pottery', but there will be a number of other functional aquarium designs I hope to work on..
such as 'Domes' ranging in a wide variety of sizes, functional for breeding caves for shelles and apistos, but glazed and sized out to fit specifications.
as well as "half-logs" and "full-logs" with a variety of styles and colors with holes and openings custom made to fit every possible situation. Also viable for reptile shelters.. Dishwasher safe! (Glaze never comes off.. so if you didn't want to scrub algae, just put in the dishwasher..)
Custom feeding dishes, with pet names imprinted for every type of critter from lizards to fish, and cats to dogs.. How many people do you know have an algae feeding cup with your prized plecos name imprinted onto the side of it? (ChubChub's feeding Dish - Spirulina only!)
Lots of ideas to throw around..
I am wondering if my 'example' piece doesn't really capture the concept I am going for.. perhaps if you saw the pieces in person, as most my guests rave over how natural and aesthetic they look in all my tank designs..
