A quick dusting with talc and then a quick slap together of the two mould halves to get rid of the excess talc often helps with this sort of work. Its not that the talc is some sort of lubricant its that the small amount left on the mould surfaces aides in getting the air out and you get a better reproduction of the mould surface.... Martin
Hey, Jeanie. Thanks a lot for posting this video. Comments on the replica compared with the original at the beginning part. Again, the original one is much clear cut line and lacquer paint. But all of the principle of making badge just like what you showed in the video. Great and nice metalic material on your badge....................... Wish good sale.........................STF.............
Thanks for posting this, Jeanie. I second Stuart Arts question: What is the tumbling medium? Could you show a video showcasing the process you use? Thanks again!
Hi Jeanie! Amazing! I tried pewter casting from one-part molds and I'm getting crazy bubbling :(. Is there a trick to get it not to bubble or do I really need a two-part mold? Also, do you have a patreon where you teach/share stuff? I love your work.
are you talking about bubbling when you make a silicone mold? or when you cast the pewter into the mold? bubbles in silicone are normally caused by too vigorous stirring if its really bad then use a vacuum chamber before pouring into mold - if your getting bubbles in the pewter casts then this could be something to do with the silicone itself trapping moisture - ensure you use a high heat resistant silicone, apply a small amount of talc into the mold before pouring the pewter! hope this helps
Hey I hope someone can help. I made a similar 2 piece mold out of Mold Max 60 however each time I cast the completed pewter figurines keep coming out completely covered in bubbles.... Any ideas if this can be fixed or should I create the mold again????
Hey Adamson, maybe I can help, when casting in any format be it, lost wax casting, sand casting, and mold casting you need to have air vents, these are skinny lines dug out from the mold going out wards towards the edge of the mold with no vents when you pour the pewter, or any metal it traps air giving you the pitted look, the air is trying go make its way out and the only way is through the metal it self, so make vent in you mold also a little tip blacken the mold cavity with a candle to help air flow out and the casting release better. Hope this helps.
@@JohnnyUrbanWoodsmen This is a game changer for me too! Thanks Johnny! Any tips on doing pewter casting with a one-part mold? I'm getting crazy bubbles with my one-parter
