regular mason jar Threader,thread maker, collar, threads, , 70/400, thread mold
$12.00
Make threads on your pots to attach mason jar pumps. These are made with 13% or 12% shrinkage calculated in the size, I personally use them on cone 10 B mix. If I make 10 bottles by the time I get the last one done the first one is usually firm enough to remove the collar and use again. I spray a little WD-40 in the threads to make sure the clay doesn't stick and removal is easy. Place the collar on a narrow neck bottle and using a finger or small tool pull the clay up through the collar and against the threads to get a good impression. Trim the top level and set aside to dry, when leather hard you can remove the collar carefully. Do not smooth the threads very much with a sponge or you will change the size, better to wait until it is dry. I will try to get a video made of using the collars when I next make bottles.
I get my pourers and pumps at onedreamdesign.com

I haven’t had a chance to test this Mason jar sized threader, yet. I have used another similar threader by this seller and it worked exactly as expected. I now have soap pump dispensers available for sale! This seller has also been very responsive to my questions about their products.
