Casting Body Parts with Alginate and Fine Casting Plaster

[@dancoleman1269]

Excellent, excellent, excellent instruction. Thank you!

[@helensmith1648]

I have been casting for many years with many materials, a couple of things about this, you don't really need a pot/tube that big, you can see how thick the set Alginate was but the main thing is how the plaster was mixed, and too much, best to pour the water into the mould then out again into a bowl or tub, you then sprinkle the plaster into the water not to fast and let it settle filling till it's just below the top of the water, little islands of plaster above and let' soak for a min or 2, it won't go hard then mix it, it will be a lot smoother fewer chances of lumps or air bubbles in your cast. I would use a brush to coat the insides of the mould with the plaster before pouring the plaster again less chance of missed parts or bubbles holes in the cast. hope that helps.

mam can you plz recommend wholesale vendors for good alginate?

[@dazzlingdarling3328]

Mam i am new to this hand molding powder I don't know the amount of alginate powder for 2 hands molding Can you plz explain

[@الباشاتلميذ-ي9ف]

How much alginate in grams to make 2 hands and how much water in liters?

[@ecfibreglassuk]

Many thanks for the tips I will certainly try that procedure next time we do a cast. its always good to hear from professionals who do this on a more frequent basis. your right the container was a bit big but it was all we had at the time. 😀

100g alginate powder How many litter water is needed? If we can mold a hand using 100g alginate powder

[@dakotap3008]

I found your video very helpful. The only questions I have are, 1) How long do your hands remain in the alginate before you wiggle them out and 2) How long does it take for the plaster to dry before you can peel away the alginate? Thank you.

[@ecfibreglassuk]

To answer your questions - 1) It depends mainly on how warm the water is, but it is very fast - only a minute or two, and you can tell when it has set. 2) Again, this depends on the type of plaster, room temperature etc but you can tell when it has dried as the top open part will go hard. Hope that helps! :-)

nice. can one pour in liquid resin? also can one save the mold?

Yes resin would also work. The mould is single use. You'd need to use silicone or latex

Although i mix it within 40 seconds but it became hard and i had to waste the mold i need to cast a hand can you please help me in mixing and using exact amount of water and alginate powder i used Alginate impression material which i bought from dental store

[@anjaliagarwal2923]

how much water did you used in 450 gms pack ? in liters?

[@ecfibreglassuk]

Hi, for small impressions you should use a powder:water ratio of 1:1 or 1:2. For larger impressions this can be increased to 1:3 or 1:4.

[@sallyleads7037]

Great video, thank you for sharing and few questions ...... can product other then plaster of paris be used inside mould please? Also is alginate only product that you use with water, or can you add another chemical to make it reusable please to make 2 or more of same mould for family. Thankyou

[@PascalD87]

Hey there, just for anyone wondering, the process cant be repeated with alginate, as soon as you used it once you can throw it out. (Technically you could also eat it, its edible)

May I know the ratios of water:aliginate powder and water:plaster of paris?

[@ecfibreglassuk]

Alginate - For small impressions you should use a powder:water ratio of 1:1 or 1:2. For larger impressions this can be increased to 1:3 or 1:4. Fine casting plaster - Water addition ratio of 100:70 - or 1kg of plaster to 0.7 litres of water - sets in 13-20 minutes at room temperature.

I can't help but point out that you should read Ronald Reagan's autobiography. Specifically the part about his tailor....

[@ecfibreglassuk]

Have you commented on the right video?!

[@MatHelm]

Yep. It has to do with your unconformable shirt collar there. There's a little tailor trick/adjustment to altering the collar that he used all his life. Once it was shown to him of course. Plus it's actually a good read irregardless of one's politics..

[@MatHelm]

btw, you won't hurt my feelings by deleting this comment, as it has nothing to do with the video itself. I've just had several people be so grateful for that tip over the years..
