Underglaze pen, Underglaze Marker, Soft Tip Design Great for Ceramic Pottery Bisque, greenware - Pack of 1 Black

Game changer! It writes and produces a sharpie-like line, so smooth and easy to use. I used on bone dry clay before bisque fire. Love.

Lo quiero de todos los colores!

This Neat little marker is a great way to add fun designs to you pottery before firing to cone 6. You can add this to greenware or bisque ware and then fire for finished, permanent design. I have not gotten a chance to use this yet, but the directions say it can be fired low-to midrange and will work fine. I want one in every color! How fun! and easy to use. I think this is priced very fairly as well.

Great brush tip and surprisingly smooth application.My only complaint is that the underglaze is basically impossible to remove on bisqueware. I messed up a circle and tried to wipe it off with a damp sponge. All it did was create a massive smear. Kept wiping with more water and it just got worse. Tried using rubbing alcohol as well to remove and no dice. Really strange because I can wipe away underglaze on bisqueware with no issue. Not sure what it is about this pen that makes it different.I tried to wipe it off on both white stoneware and porcelain bisque and had the same issue on both.Maybe it’s easier to wipe off on greenware? I was only able to remove it by sanding.Basically, this is a sharpie. Once it’s on there, it’s on for life!

Broken tip immediately

This is a really cool idea! The underglaze flows well, but works best on dry clay. I've been using it to put my initials on the bottom of my pots and I do that right after trimming. Its pretty streaky and kind of digs in. I tried it on dryer clay and it works so much better! It's got a decent brush tip.

Decided to just use underglaze and a paint brush to put detail on my pots as needed. This was terrible and bled so bad, I couldn't get it out of the clay, so had to ultimately cover it with a total color that I didn't want to have to do. Not worth the money.
