Most of IMD molds are very self-explanatory and don't need any additional casting instructions. But for few designs we would like to offer pouring suggestions.

Casting Tiles

All IMD tile molds pour through two (smaller tiles - one) pour-hole. Biggest problem with pouring solid tiles always was - small pour-holes. Ceramist had to keep adding slip every minute or so. IMD manages to solve this problem with "Reservoir" molds IMD-600. They allow you to keep an access of slip over pour-holes, so you don't have to add more slip every minute. If you tried to pour tile or plate mold with closed bottom (it does make a very nice back side) then you are familiar with that problem. You have to keep mold full all the time to prevent it from trapping air inside. And what a task it is. With IMD "reservoir" molds you simply place them over pour-holes and you wouldn't have to worry about adding your slip again. Simply place them over pour-holes and 15 min. later just slide them off.

When you are ready to open tile mold you have to trim pour-holes as deep as you can reach without damaging tile and then open back part first. Then trim whatever left off pour-holes and when tile bottom is nice and clean put it on piece of Styrofoam and flip it over. We prefer dry tiles on Styrofoam as well.

Casting Sushi Set

When Casting Sushi Dishes use same casting technique as for tiles (described above) using IMD600 reservoirs. Legs on the dishes are casted together with a body of a dish as one piece. When you open bottom part of the mold you'll see an indications on the rim where to trim it. After you'll cut out excess of the rim all what’s left will make you four legs. That way all your castings will look identical.

Casting IMD640 Chess Board

Many mold companies tried to develop ceramic chess set board before but biggest problem was that they all were warping in the kiln. IMD engineered a new board with reinforced bottom. It does come out straight every time. Two castings will make a board. It pours solid through two small holes on the bottom and it also made a very nice, clean board bottom. When IMD640 Chess Set Board use same casting technique as for tiles (described above) using IMD600 reservoirs. We also suggest when pouring tilt mold a little and pour it from lowest hole. That will push air through the top hole. Open bottom first and clean pour-holes. To make bottom part of the mold dry faster then top you can use some "baby powder" on it.

Casting IMD634 Lg. Garden Cherub.

We developed a very helpful casting technique for casting IMD634 Lg. Garden Cherub as well as any other large mold. When your green-ware is ready to come out from the mold (right before you open your mold), you fill it up with packaging peanuts. Soft peanuts will work better because you can pack them tighter. Soft peanuts will also allow your green-ware to shrink while it's drying. Peanuts will provide support for your green-ware from inside and will help to avoid any sagging, leaning or collapsing. After you packed with peanuts open one side of the mold (pour-hole is still up). In order for peanuts to stay inside you simply glue a piece of paper over the pour-hole. It will keep peanuts from falling out when you tern your piece. Now your item is ready to come out. When your piece is dry and ready for firing, you rip paper off and get peanuts out. Little pieces of paper staked to green-ware will burn out in firing.
