Anodizing Dye Heater?

Hello,

I am using anodizing dyes, and was wondering what I can use to get the dye up to the optimal temperature? I have looked into fish tank heaters, but I think they only go up to around 110 °F Thanks!

Hello Graham. What temperature does the vendor recommend...what is your tank made of...how big is it...do you have steam or hot water boiler (probably not). You probably need an electric heater from a plating equipment supplier, but depending on tank material this may be too great a fire risk for a residence.

There are a few fish tank heaters that will go higher, but you probably will have to special order it. Another way is to deform the thermostat in it and watch it constantly and un plug it when it gets to temp. This is begging for a fire, so it must be watched or unplugged. There are small plating heaters with the thermostat built in and there are some very simple bulb type thermostats that are affordable when compared to the high priced ones. That, is the price of anodizing.

The vendor's suggested temperature is 150 °F. I am using a tupperware container right now that contains 2 US Gallons of dye. Thanks.

With plastic containers you need to be very careful of excessive heat. I think you need a small electric heater with proper overheat protection. If you search our directory of Equipment with the term 'heater' you should find vendors. Good luck.
