Being new to this, what's the deal with butterscotch brushes? It seems it's merely a handle color, but they also seem to be more expensive, which makes me think I'm missing something. They do look cool though...
The old true butterscotch handles started out as a ivory color, and over time due to UV light and a chemical reaction(i think) they turned that color. If you restore a vintage butterscotch brush you will see the true color once you get the knot out, because it hasn't been exposed. The new brushes are turned from a blank of that color and they are just playing on the color by raising prices.
Older brushes made out of Catalin would turn a Butterscotch-like colour over a period of years and there has been a modern trend to try and replicate this colour by a number of manufacturers.
Some brush makers do indeed charge more for this whilst others do not (for example I was offered a Butterscotch or Bone M&F L7 brush for exactly the same price for either model by the maker - chose the Butterscotch option and am well happy with it).
I don't know what the cost/price differences are. I simply like the way they look. Although I'm a huge fan of M&F, I prefer Simpson's butterscotch handles; they are a deeper, richer ... butterscotch.
I haven't noticed any improvement in relative performance. But when I dream about brushes, they usually have either butterscotch or jade handles.
There is nothing quite like a true vintage butterscotch brush that acquired the color the old fashioned way. When interest in these brushes caught on and brush makers tried to replicate the color in modern materials, I found them to be too yellow or orange. Lately, I think the brush makers are doing a nice job capturing the color.
Here's a pretty interesting read at "the bay"... particularly the part about " Note; Many original Bakelite and plastic's workers died of Larynx or Lung cancer related diseases. Many were fairly young when they died.Wear a mask if you are testing with a saw, drill or hot needle!" http://reviews.ebay.com/BAKELITE-TESTING-amp-A-BIT-OF-HISTORY?ugid=10000000002564429
I just ordered a new brush for soaps and told the vendor, who is a boutique brush maker, that I was willing to wait a few weeks if he could turn one out in butterscotch. Alas, he has no plans to do so as his faux ivory is selling well. So, ivory it is. Not really disappointed, but butterscotch would have been cool.
