In this demo OCC instructor Alan Paulson is showing how to make a plaster mold for mass producing ceramic pieces. The demo shows a mold being made for a 6"x6" tile, but this technique has limitless uses.

Great video most important thing i like about this and learned from it. Is layer you buckets with plastic so you don't have to clean them out quickly/right after alot less mess/saves the buckets. Also i like the metal brackets if they are as good as using wood working clamps that would save the need for them and make the resizing of the mold boxes much quicker in setup time.

Very nice tutorial on a one part plaster mold! There is one thing I realized towards the end that could be added! Adding a release agent (like murphy soap) before pouring the plaster would make the terracotta piece dislodge almost completely after hardening! Then, you wouldn't have to risk chipping or cutting into the plaster while digging out the clay piece! ^^

+Ediel Dominguez a simple tip you are pouring the plaster to early. Wait till when you pass your finger through the plaster and it starts to leave a trench in the plaster this is when you pour the plaster. This will stop nearly all the leakage problems. It's a shame you live in another country I could teach yo so much. A lot of mould making secrets are kept within the trade. I live in Australia and learnt a lot about mould making from a mould maker that worked in potteries in Sydney before ww2.

I would like to make slip molds, i understand that plaster is ideal with a gypsium mold being that the gypsium retains the water from the plaster hence creating the slip effect. Unfortunatly down here i cant find gypsium, my question, can i use stone lime powder to make the outer mold? I do have acces to plaster. Or could i make the outer mold from.plaster and the slip cast from.plaster also? I would appreciate a response ty.

But you need to work quickly, as once its in the water and you start mixing, it will start hardening. Not IMMEDIATELY but fast enough where you wont want to dawdle.

@rook5439 жыл бұрын
Nope. You are not going to let the clay dry. Frankly, you will be destroying your original. Once the plaster is hard, just pull the clay out, clean up the mold, and you are good to go. Frankly I would wait a couple days until the plaster is rock-hard before using it. Some DO use vegetable oil spray if it's needed when running production pieces with the mold though.
@rook5439 жыл бұрын
I have no idea how the plaster would react to aluminum. Never tried it. Hot water WILL eventually break down the plaster of you get some pieces of plaster caked on it. What will you be making your pieces with once you have a mold? Depending on what, you may consider using silicon or some other material.

@silk25859 жыл бұрын
proflooney hi, when I did my degree course, we were taught to use soft soap, just a really soapy water mix. What you do is take your model and soak it in water until no bubbles are coming out, it needs to be totally saturated. Depending in the size, this can take from an hour to about 3 hours for something about the size of a middle sized watermelon. Then you take it out of the water, mop up the excess and start soft soaping, you need to do at least 3 coats (you will be surprised at just how absorbent the plaster still is when you do this process!). This will prevent the new plaster from sticking to the model. The soap will not transfer to the mold. Good luck, and watch those undercuts!
@proflooney9 жыл бұрын
Silk thanks silk I got a bottle of tincture of green soap in i will try this out very clear instructions from you i know it says something abt being saturated but wasnt sure what they meant you cleared that up really good. gonna have some fun next week seeing if i can do one. not sure if i spotted any undercuts but if there is any they should be really minute and the shrinkage of the plaster should take care of that
@silk25859 жыл бұрын
proflooney it's actually been 7 years since I did and mold making and I remembered this morning that I forgot a couple of steps. When soft soaping, you actually paint it on neat, then sponge it off with water, then paint it on again. The model will take on a nice warm waxy/satiny sheen when this is done properly. It was the last step in my favourite part of the process. I loved making the models, hated making the molds!

Silk ok thanks yes I have some rubber molds for stones and rocks from the model train industry.

That's about the lumpiest blob of plaster mix I've ever seen. Don't do that folks, mix the plaster well and thoroughly, especially if you are going to carve the plaster. If you don't you are risking that the plaster is not cooked correctly in some areas and once you start carving you may experience chunks of plaster breaking off and ruining your work. I use a plastic bucket and a hand mixer bit that attaches to my hand drill. You can get one of those at any paint store or hardware store. If you use low quality plastic buckets and you are using them continuously for mixing plaster you will only get a limited amount of use from them as the heating of plaster will deteriorate the plastic bucket. Invest in a good quality bucket and you can get many uses on them. The instructor here is correct when he states to not dump the liquid plaster in any drain, as in time the plaster will clog your drainage pipes and you are going to pay quite a bit to get those replaced. Just let the leftover plaster dry on its own inside your bucket and toss the dry pieces into your trash bin.

That seems like an obvious way of doing it, but it will lead to disaster. Don't do this! Grease/petroleum jelly will clog the pores in the plaster, sealing it and making it useless for slip casting. The plaster needs to be able to absorb moisture from the clay slip in order for this process to work.

+Linda Gordon These ones are made with 1" x 6" boards. On the end of each one you screw an "L-bracket" so it can hook onto the next sine. It noes not need to hook over perfectly, but you want it without TO much wiggle room. Each side hooks onto the next at a 90 degree angle. This lets you use longer board and you can slide and size the mold form to your piece. As for keeping the clay from leaking out, when you are going to pour your plaster, you use clay on the corners and where the board touch the table and form corners to keep plaster from leaking.
