Just returned form a long absence and tried to make gweths again. No trouble studying the gweth instructions in the book, or affixing the j-oil dipped k-stones to a silver chain. ~300 Enchanting, plus techs.

The fount I used was for major enchantments, uncommon materials.

Twice I received the following message after casting 90 mana imbue after placing the fount.

What am I doing wrong? Does my fount need to be for better materials?

>cast gweth on braz
You gesture at an unfinished gwethdesuan.
The spell is channeled through the fount hanging above, and down into the gwethdesuan. With expert precision you rapidly direct each stream into place around the gwethdesuan.
Roundtime: 9 sec.

You need another induction primary sigil to continue the enchanting process. You believe you can STUDY the sigil and then TRACE it on the unfinished item to prepare it for continued scribing.
[Sigils can be added to the artifact to continue crafting.]
A surge of mana churns through the brazier. The imbue potency was insufficient to contain such a high grade of enchantment, and the matrix is growing unstable! With a loud snap the enchantment breaks, damaging the gwethdesuan in the process.
It does not seem possible to continue with the enchanting process, and you will need to start over.
