hello there and here we are today and we're going to be talking about molds latex molds and why they
go brown and um does it affect the casting process when they've turned brown so i've got a selection
of molds here latex molds as you can see and they kind of like a different shade of brown
this one's like the color that you would expect the mold to finish up like once you've
gone through the process of applying your layers and then obviously after the mode is
cured so i'd say see that one is like a nice healthy looking latex mold and then there's
kind of a grade in between and then there's like a brownish like a very dark brown looking shade of
brown on this latex mold here now there are quite a few people have asked why they go
brown and i'm gonna make some suggestions i don't know totally why they do go bramble
tell you what i think causes them to go brown so like i say uh like this one here is a dark
shade i've had some molds that have gone even darker than this like i like a conquer
type color but anyway it doesn't seem to affect the quality of the mold it's just that it looks
darker brown than what the what you would expect sort of thing so as to the reasons why and i don't
know if this is for sure but i'm just guessing and it seems to have happened when i've been making
my own molds and when i go brown it seems to be that sometimes if you're molding a painted object
there may be um a reaction with the paint and the latex and in some cases that might damage the mold
and you'll know if it does in this case here it hasn't and i haven't had any problems before
with casting painted objects and i haven't come across anything that um deteriorates the mold as
in paint while creating the molds um so this mold here was a mold i made it's like just a
little fairy door sort of thing which i sculpted up i think there might be a video on the channel
of me doing that i can't remember if there is or not anyway so yeah so that could be the reason why
this mold went uh brown also it could be down to the temperatures and conditions you're working in
that could be a factor but like i said i'm sort of guessing here
um i mean also this mold here which is the color that you would expect which is a skull
a little small skull mold um i actually uh made the mold from a painted object with this
mold and this one turned turned out as you would expect nice almost sort of perfect latex mold
this mold is just slightly darker and not too much darker um again it would be like
uh the the color of latex that you would expect once it's cured this was actually casted from
a small buddha cast which wasn't painted it was just like a kind of um ceramic ornament
so like i say i think that so why the molds go um brown like this brown or even darker
is maybe because of a reaction to the material for example paint on your object
temperature conditions maybe the make of latex i think these latex molds are all made from the
same make so um i would imagine in this case this would have been perhaps a reaction to some
paint that i'd painted on the object like i said a thousand times already in this video and like i
said i haven't had any problems with the molds uh quality wise there doesn't seem to be any problems
in deterioration or quality in detail when the molds have turned this darker shade of brown
um when i've made these molds so anyway um if anybody else has got anything to add
and they might uh think of some more reasons why the latex goes brown after molding then uh please
let us know and post your comments in the comments below and uh there'll be some more frequently
asked question videos coming up over the course of time and um i think that's about it for this
video like i said if you've got anything to add uh post your comments in the comments below and
uh hope you enjoyed the video um and we'll see you soon thank you for watching over and out for now
you
