I finally returned back to clay work this week after moping/cleaning the studio a bit. I have taken 6 week break from clay work after x-mass. Taxes are ready now for accountant and I was able to take a photo of what mixers I use almost every week.
I have them for any size bucket or condition of glaze -Hard settled or mixes easy-Huge bucket or tiny test batch -the red one was just given to me to try and I will next week-the metal ones I have used for years and wear them out and then replace them-I always have a few new ones in boxes ready to go
I use the largest ones every week as well as the smallest-I keep a few 1/2 shaft diameter ones in 1/2 corded drills ( my glaze area has a low ceiling outlet above to plug these in overhead) and a few med to smalls in cordless drill drills.
These are high use tools for me and when they wear out -I need one that day so I keep them in stock. The hanson (brand name) ones (the ones with the thicker stouter materials have yet to wear out -the Jiffy mixers I wear out every few years. I use flat bottom buckets do not go thru the bottoms.
The hansoms really work best on hard settled glazes but do not mix the whole bucket as well as a Jiffy but the jiffy's do not work the hard bottom glazes as well-hence both kinds always at the ready. After mixing the bucket with these I use wood glaze sticks to stir that glaze day.Every bucket has a stick.
Hope this helps on choices
