There are many ceramic suppliers across the country. SInce I don't know where you are located I can offer the following. The link below is to my web page that has a listing of ceramic suppliers I use. Some are in the northeast, like Bailey Pottery, Ceramic Supply, and Sheffield Pottery, where I live. If you are in that area, then they deliver on a regular basis. For many things I shop around, and both Axner and Bennett's in Florida have very good prices. But check for sales on different items. At these suppliers you can get kilns, wheels, pug mills, clay mixers, grinders, glazing machinery and more. If you are wanting to go to the supplier, then google ceramic suppliers in your home town. Many times you will want to actually try out the equipment, such as a wheel. The third option is used equipment that you can find on Ebay, Craig's List, your local penny saver or Bargain News (if you have that paper). I have found deals at estate sales and also by checking the bulletin boards at local art schools and craft centers. Good luck with your search.
Since this is sculpture, I guess you are asking for hardware related to working and firing clay. So the answer would be a ceramic or pottery supply firm like Trinity Ceramic Supply here in Dallas or Seattle Pottery Supply in the obvious place. Because of the weight of shipping you should always consider the closest place unless they don't have the specific item you want. If you meant something else, a lot of details would help.
